Use a pipe cap of the same material as the pipe.

601.03 Construction  back to top

601.03.01 Installing Pipe

  1. Storing and Handling. Handle and store pipe to prevent damage such as cracking, denting and breaking. Lift pipe off of the delivery vehicle to avoid damage while unloading. Do not dump or drag pipe off the delivery vehicle. Store pipe in an area where it will not be damaged during construction operations. Use blocks or straps when stacking pipe. Alternate the bells and spigots to reduce the load on the bells. The RE will reject pipe that is damaged, bowed, or considered unacceptable for other reasons.

  2. Excavating. Maintain the existing drainage system during construction until the new drainage facilities are completed and placed into service.

    Excavate the same distance on each side of the centerline of the pipe to ensure that the pipe is in the center of the trench. Ensure that the trench is at least 18 inches wider than the outside diameter of the pipe. Provide vertical sides for excavations within the traveled way, shoulder, sidewalk areas, and where existing facilities require protection.

    Except where necessary to maintain flow, do not excavate trenches or place drains in embankment until the embankment has been constructed to an elevation of at least 3 feet above the top of the pipe or to the top of the embankment, whichever is lower. Do not excavate trenches more than 300 feet in advance of installing the pipe unless approved by the RE.

    Obtain RE approval before finishing excavation. If the RE determines that the bottom of the trench is unstable, undercut as directed by the RE and backfill with Class B bedding.

    If the material at the bottom of the trench is rock or other hard material, remove at least 6 inches of the material for RCP or at least 12 inches of the material below the bottom of the pipe for corrugated metal, steel, aluminum alloy pipe, or HDPE. Backfill the undercut with Class C bedding.

    For trenches in the traveled way, shoulder, and within 30 feet of the outside edge of the shoulder, backfill and restore the pavement structure to match the surrounding pavement before opening to traffic. The Contractor may submit working drawings for approval for temporary protection instead of backfilling trenches.

    Provide and maintain trench crossings where necessary. For trenches not in the traveled way and shoulder, do not leave trenches open overnight unless protected with fence. Maintain trenches according to 29 CFR 1926.

  3. Bedding. Do not place bedding material until the RE approves the depth of excavation and the material at the bottom of the excavation. If bedding is not shown, place pipe directly on the material at the bottom of the trench.

    For Class A bedding, construct a concrete cradle. Place concrete according to the limitations specified in 504.03.02.C. Place concrete across the area to minimize rehandling. Ensure that concrete is not discharged into windrows or piles. Consolidate the concrete by hand spading or using internal mechanical vibrators. Protect concrete as specified in 504.03.02.I.

    For Class B, Class C, and Class D bedding, place the bedding and provide recesses for pipe bells deep enough to ensure that the bell will not rest on the bottom of the recess. Ensure that the recess does not exceed 2 inches from the edge of the bell along the length of the pipe. Compact using the directed method as specified in 203.03.02.C.

  4. Installing Pipe. Before the installation of HDPE pipe and as directed by the RE, provide a technical representative from the pipe manufacturer on the work site for the first day of pipe installation to ensure proper installation procedures.

    When installing pipe, use a laser system to control the alignment and grade of the pipe.

    Use end sections of the same material as the adjoining pipe or pipe arch, except use concrete end sections for HDPE pipe.

    Begin installing pipe at the lowest elevation of the pipeline. Ensure that the pipe is in firm contact with the bottom of the excavation or bedding throughout its full length. Place bell ends of pipe facing towards the highest elevation. When using perforated pipe, ensure that the perforations are at the bottom.

    When installing pipe through concrete or masonry walls, provide a sufficient length of pipe outside of the wall to allow for connections, and cut the pipe flush with the inside face of the wall. Seal the connection using mortar. When pipe enters below the invert of existing structures, cut and shape the existing invert to form a new channel.

    When constructing storm drains in stages, cover the end of the pipe after each stage to prevent material from entering the pipe. Do not cover the pipe if it is required to keep the pipe open for temporary drainage.

    When using pipe for a stream diversion, install pipe outside of the existing stream bed while maintaining flow in the existing stream. When installing pipe within an existing stream channel, construct a temporary stream diversion while maintaining flow in the existing stream channel. Once the temporary channel is completed, divert the stream flow into the temporary channel while constructing the pipe system within the existing stream bed. When the pipe is completed, divert the stream flow into the pipe.

    When using heavy construction equipment (100 kips axle load) over, or within 10 feet of HDPE pipe or corrugated aluminum alloy pipe, place the manufacturer recommended temporary compacted cover over the top of the pipe. Ensure that the temporary cover is free from stones larger than 1 inch.

  5. Joining Pipe. Join rigid pipe using mortar or gaskets to form a watertight seal. With RE approval, the Contractor may use other types of joints that are recommended by the pipe manufacturer. Join corrugated metal pipe with coupling bands.

    For mortar joints, clean the pipe ends and wet with water before placing stiff mortar. Place mortar in the lower half of the bell of the placed pipe section, and then place mortar on the upper half of the spigot of the section to be installed. Join the 2 pipe sections with their inner surfaces flush. Seal the exterior of the joint with mortar. Fill the lifting holes with mortar.

    For circular pipe greater than 36 inches in diameter and elliptical pipe greater than 38 × 60 inches, ensure that the inside of the joint is finished smooth. For circular pipe smaller than 36 inches in diameter and elliptical pipe greater than 38 × 60 inches, remove protruding mortar from the joint. If the completed mortar joints are not immediately backfilled with earth, protect the mortar joints against rapid drying. When the ambient temperature is below 40 °F, ensure that the mortar temperature is between 50 and 100 °F. Protect the mortar and maintain its temperature above 32 °F for 24 hours.

    For gasket joints, install gaskets according to the manufacturer’s recommendations.

    Do not use split couplings to join field-cut HDPE pipe unless approved by the RE. Ensure that joints are bell and spigot type, or bell and spigot type with a gasket, according to ASTM F 477, to provide a silt-tight seal. Construct pipe connections according to the manufacturer’s recommendations for assembly of joint components, lubrications, and making of joints. Ensure that the pipe fittings are free of inclusions and visible defects. Cut the ends of the pipe squarely so as not to adversely affect joining.

  6. Backfilling. When using corrugated aluminum and HDPE pipe, backfill from the bottom of the trench to 2 feet above the top of the pipe with Class C bedding. When using pipe other than corrugated aluminum or HDPE, backfill from the bottom of the trench to 2 feet above the top of the pipe with suitable excavated material free from stones and rock larger than 2 inches in any dimension. For distances 2 feet above the top of the pipe, backfill using suitable excavated material.

    Place backfill material symmetrically on each side of the pipe in lifts not exceeding 6 inches thick, loose measurement. Compact as follows:

    1. If the backfill material is predominantly granular, use vibratory plate compactors.
    2. If the backfill material is not predominantly granular, use vibratory rammer compactors.
    3. For heights more than 2 feet above the pipe, the Contractor may use a roller.

    The RE may direct compaction using the density control method as specified in 203.03.02.D.

    Remove shoring, bracing, and sheeting as the backfilling proceeds.

    The Contractor may use CLSM as alternate backfill material when backfilling trenches for drainage pipe. Do not use CLSM to replace pavement, base courses, or drainage layers that form the pavement structure. The RE will not allow combining other backfill materials in the same trench as CLSM. Place CLSM according to the limitations specified in 504.03.02.C. Place CLSM across the area to minimize rehandling. Protect CLSM as specified in 504.03.02.I.

601.03.02 Installing Pipe Using Alternate Methods

When installing pipe using methods other than as specified in 601.03.01, at least 30 days before installation, submit working drawings for approval that include the following:

  1. Materials, including size and type of pipe.
  2. Method of maintaining continuous operation of traffic on the Project.
  3. Details for installing and removing sheeting, bracing, and shoring.
  4. Method of ensuring horizontal and vertical alignment of the pipe.
  5. Complete installation procedure.
  6. Method of protecting pipe during installation.
  7. Method of excavating and removing material during installation.
  8. Method of sealing and finishing pipe joints.
  9. Alternate method of pipe installation if original method becomes impossible due to obstructions.

601.03.03 Underdrains and Subbase Outlet Drains

  1. Excavating. Maintain the existing drainage system during construction until the new drainage facilities are completed and placed into service.

    Excavate the same distance on each side of the centerline of the pipe to ensure that the pipe is in the center of the trench. Do not excavate trenches more than 300 feet in advance of installation unless approved by the RE.

    Obtain RE approval before finishing excavation. If the RE determines that the bottom of the trench is unstable, undercut as directed by the RE and backfill with Class B bedding.

    If the material at the bottom of the trench is rock or other hard material, remove at least 6 inches of the material for RCP or at least 12 inches of the material below the bottom of the pipe for corrugated metal, steel, aluminum alloy pipe, or HDPE. Backfill the undercut with Class C bedding.

    For trenches in the traveled way, shoulder, and within 30 feet of the outside edge of the shoulder, backfill and restore the pavement structure to match the surrounding pavement before opening to traffic. The Contractor may submit working drawings for approval for temporary protection instead of backfilling trenches.

    Provide and maintain trench crossings where necessary. For trenches not in the traveled way and shoulder, do not leave trenches open overnight unless protected with fence. Maintain trenches according to 29 CFR 1926.

  2. Installing. Begin constructing at the lowest elevation of the drain. Ensure that the perforations are at the bottom. Join underdrains according to the manufacturer’s recommendations. Seal the dead ends of pipe underdrains with a pipe cap.

  3. Backfilling. Backfill, using coarse aggregate, around the underdrains and subbase outlet drains and on top of stone backfill in rock areas. Compact the coarse aggregate with a vibratory pad compactor.

601.03.04 Video Inspection of Pipe

Perform video inspection of interior pipelines no sooner than 30 days after completing the pipe installation. Submit to the RE for approval the name and qualifications of the person performing the inspection.

Perform the video inspection in dry pipe conditions to ensure viewing of the entire pipe circumference. Ensure that a visual numerical registration of the distance the video camera is traveling from the starting point to the ending point within the pipe drainage structure is recorded on the footage tape at all times. Also, ensure that the name of the pipe run and the name of the structure is recorded on the footage tape at all times. Stop the video camera at all joints, lateral connections, breaks, and irregularities to ensure full view at these locations. Ensure that the videotape provides clear, sharply focused pictures. The Department will not accept blurred or out of focus footage. Submit a color VHS videotape, or equivalent digital media, of the inspection to the RE to become the property of the Department. Number the tapes sequentially and provide a corresponding index for all tapes, listing the location, date, size and type of pipe, cross or longitudinal drains, berm, slope, and similar identifying information.

If the pipe is found to be defective because of poor joints, deformation, breaks, poor connections, or irregularities, correct the defective pipe as directed by the RE. If the pipe cannot be corrected, remove and replace the defective pipe.

601.03.05 Deflection Inspection of HDPE Pipe

Test approximately 25 percent of the length of HDPE pipe for deflection no sooner than 30 days after installation. If testing produces a failure rate of 5 percent, increase the rate of testing to 100 percent. Perform the deflection testing using either electronic deflectometers, calibrated television or video cameras, properly sized “go, no-go” mandrel, direct measurement extension rulers and tape measures in pipe that allow safe entry, or another acceptable device. If mandrel testing is chosen, pull the mandrel through the pipe by hand.

Where deflection is more than 5 percent of the base inside diameter, submit a remediation plan to the RE for approval.

601.03.06 Cleaning Existing Pipe

At least 5 days before beginning the work, submit a plan to the RE detailing the proposed method and equipment to be used. Remove and collect silt debris and material of any kind and prevent material from being discharged into the drainage system. Dispose of materials removed from existing pipe as specified in 202.03.08.

  2. Cast-in-Place. Construct cast-in-place culverts and headwalls as specified in 504.03.02.

602.03.02 Inlets and Manholes

Excavate as specified in 202.03.03. Obtain RE approval before finishing excavating. If the RE determines that the bottom of the excavation is unstable, undercut, backfill, and compact as directed by the RE.

When surrounding grade is below proposed grade, provide temporary drainage into the drainage structure as directed by the RE. Repair temporary openings as necessary. Construct inlet and manhole structures as follows:

  1. Precast. The Contractor may use precast concrete inlets and manholes. If modifications to precast concrete inlets and manholes are required, obtain RE approval before installation. After installation, fill the lifting holes with mortar.

  2. Block and Brick Construction. Lay concrete block and brick with staggered joints. Fill with mortar horizontal joints, brick vertical joints, and concrete block key ways. Ensure that horizontal joints and vertical joints in brick are not more than 3/8 inch wide. Coat the outside wall with at least a 1/2-inch thick layer of mortar and trowel smooth. When the ambient temperature is below 40 °F, ensure that the mortar temperature is between 50 and 100 °F. Cover the masonry and maintain its temperature above 32 °F for 24 hours. Ensure that the connection between drainage structures and pipe is leak-free.

Set castings in mortar beds or anchor castings to the masonry as shown before finishing adjoining Items of work with the same final elevation. Ensure that mortar attains a strength of 2500 pounds per square inch before opening to traffic.

Backfill and compact using the directed method as specified in 203.03.02.C.

Construct inverts with a smooth and uniform finish that minimizes resistance to flow. Ensure that the shape of the inverts conforms uniformly with the inlet and outlet pipe.

Set the manhole cover or inlet grate on the casting. If the manhole cover or inlet grate is loose or wobbles, grind to obtain a tight fit.

602.03.03 Setting Castings, Resetting Castings, and Reconstructing Inlets and Manholes

Set the manhole cover on the casting. If the manhole cover is loose or wobbles, grind to obtain a tight fit. Ensure that mortar attains a strength of 2500 pounds per square inch before opening to traffic.

602.03.05 Extension Frames and Rings

If structures contain existing frames or rings, remove extension frames or rings. Use the minimum number of frames or rings necessary to achieve the proposed grades. Place the extension frame or ring in the casting and check for fit.

Before applying epoxy bedding compound, clean the surfaces that will receive the epoxy bedding compound, the lower bearing surfaces, and sides of the extension frames or rings. Clean by sand blasting or brushing with a mechanically-driven wire wheel to ensure that the epoxy bedding compound adheres to the surfaces. Wipe the prepared surfaces with a rapid-evaporating degreasing agent.

Apply extra epoxy bedding compound where there are gaps in the fit. Apply the epoxy bedding compound according to the manufacturer’s recommendations, and immediately set the extension frame or ring into the epoxy bedding compound. Ensure that the frame or ring is in full contact with the casting and that the epoxy bedding compound fills the gaps.

Set the bicycle safe grate or manhole cover on the extension frame or ring. If the bicycle safe grate or manhole cover is loose or wobbles after being set in the extension frames or rings, grind to obtain a tight fit or replace as directed.

Repair damage to galvanized coatings according to ASTM A 780. Dispose of materials removed from the existing structure as specified in 201.03.09.

602.03.06 Manhole Covers and Bicycle Safe Grates

609.03.01 Beam Guide Rail

Install beam guide rail, single or dual-faced, so that no unprotected end is exposed to approaching traffic. Within the same working day, replace all existing beam guide rail or cable guide rail that is removed. Where possible, install new beam guide rail exposed to approaching traffic before the removal of the existing system.

Before driving or mounting the posts, determine the location of utilities that may conflict with the posts. The Contractor may adjust post spacing by 6 inches, as approved, to eliminate such conflicts. After completing the wiring for each electrical system and before making connections, perform the following tests on each circuit using suitable equipment in the presence of the RE:

  1. Tests for continuity.
  2. Tests for ground.
  3. Tests for insulation resistance between circuit wires and from circuit wires to ground. Verify that the insulation resistance is at least 150 megaohms between conductors, or between conductor and ground for circuits with a total single conductor length of 1500 feet or more, and at least 175 megaohms for circuits with a total single conductor length of less than 1500 feet.

The RE may require additional tests if it is suspected that conduit have been damaged. Locate and repair damage to the electrical conduit due to construction operations.

Drive beam guide rail posts to the required position. Ensure that posts are driven plumb, properly spaced, and to the line and grade shown.

Install the required bridge attachment type as shown on the Plans. Mount bridge beam guide posts as shown on the Plans.

Attach the beam guide rail element to the spacer at every post. Align the top edge of the beam guide rail element in a straight line or smooth curve, parallel to, or concentric with, the traveled way. Where a vertical transition is required, ensure that the top edge of the beam guide rail element forms the chords of a smooth vertical curve. If adjustments to the rail element are necessary, obtain RE approval before punching, drilling, or reaming of the rail element. Do not cut or weld the rail element.

Install flexible delineators with white retroreflective sheeting on the right side of the direction of traffic.  Install flexible delineators with yellow retroreflective sheeting on the left side of the direction of traffic.  Mount flexible delineators on the blockout of beam guide rail using either a “U” channel base on the I-beam blockout or a flat base attached to a wood, polymer, or other solid top blockout.  Attach the base to the blockout using an adhesive recommended by the manufacturer of the base and panel.

Mount the first delineator on the beam guide rail end treatment so that the plane face of the center of the reflective area is at an angle of 0 degrees with a line that is perpendicular to the direction of traffic. Mount subsequent delineators every 81.25 feet (13 sections of guide rail) along tangent mainline roadway, or every 43.75 feet (7 sections of guide rail) along curved mainline roadway with a radius of less than 1910 feet. If a parabolic flare in the beam guide rail exists, place the second delineator at the end of the flared section with subsequent delineators spaced as stated above. If the distance between the last delineator and the end of the beam guide rail is greater than 40 feet on tangent mainline roadways, or 20 feet on curved mainline roadways, mount a delineator on the last post or end treatment.

Repair damage to the galvanized coating according to ASTM A 780.

609.03.02 Rub Rail

When rub rail is required, bolt rub rail consisting of a steel channel or a bent plate to the beam guide rail posts.

609.03.03 Terminals and Anchorages

At least 10 days before beginning the work, submit the manufacturer’s recommendations the RE. Install terminals and anchorages according to the manufacturer’s recommendations.

Excavate for post holes and concrete anchorages as specified in 202.03.03. Backfill and compact using the directed method as specified in 203.03.02.C.

Excavate cut slope as specified in 202.03.03 within the limits of the buried guide rail terminal.  Drive beam guide rail posts for buried guide rail terminal to the required position. Ensure that posts are driven plumb, properly spaced, and to the line and grade shown.  Attach the beam guide rail element to the spacer at every post.  Attach the beam guide rail element and plate to the terminal posts.  Align the top edge of the beam guide rail element in a straight line.  Where a vertical transition is required, ensure that the top edge of the beam guide rail element forms the chords of a smooth vertical curve.  Backfill with excavated material as specified in 203.03.02.C.

609.03.04 Beam Guide Rail Blockouts

Where required, attach blockout on existing beam guide rail between the steel posts and rail elements.

Where beam guide rail is attached to a structure, attach the blockout to the structure. Reset beam guide rail, as specified in 609.03.05, to provide a smooth transition to the existing structure.

609.03.05 Reset Beam Guide Rail

When the RE determines that the beam guide rail is suitable for resetting, dismantle, store, and protect the components until resetting. To ensure that the beam guide rail meets the current standards, replace existing components, replace damaged components, and provide necessary new components. Dispose of components not designated for resetting the beam guide rail as specified in 201.03.09.

When storage is required, remove the bolts, cables, and other hardware from beam guide rail element, posts, and other members. Sort the components and store until resetting. Stack rail elements and ensure that cables are free of kinks. Replace beam guide rail components that are damaged, lost, or missing in storage.

Reset the existing beam guide rail, as specified in 609.03.01, using the salvaged components. Use all the salvaged components before providing new components for resetting.

Where feasible, use existing rail elements in guide rail sections or portions thereof that are reset with existing posts, and use new rail elements in guide rail sections or in portions thereof where new guide rail posts are used. When it is necessary to use existing and new rail elements in the same guide rail section, install a continuous length of each.

609.03.06 Removal of Beam Guide Rail

After removing beam guide rail, backfill the post holes and compact the area to the elevation of the adjacent surface. Dispose of beam guide rail as specified in 201.03.09.

610.03.01 Traffic Stripes

  1. Striping Plan. At least 20 days before beginning the work, submit to the RE for approval a striping plan that includes:

    1. Schedule of operations for applying traffic stripes.
    2. Number and type of equipment.
    3. Manufacturer’s recommendations for use of the materials, including, but not limited to, mixing ratios and application temperatures.
    4. Details on the means and methods for surface preparation.
    5. Details on the means and methods for premarking.
    6. Details on the proposed test strip such as location, length etc.

  2. Surface Preparation. Immediately before striping the pavement surface, clean the surface of dirt, oil, grease, and foreign material, including curing compound on new concrete. Clean the surface 2 inches beyond the perimeter of the stripes to be placed.

  3. Striping Test Strip. Before beginning striping operations, construct 1 or more striping test strips to demonstrate the Contractor’s ability to meet the requirements specified in 610.03.01.D. For each striping test strip, apply striping to approximately 500 linear feet of pavement with the same striping procedure that will be used for the Project. Construct a test strip for each applicator unit and epoxy resin material used. Provide the RE with 50 test cards made of heavy stock paper measuring 8 inches by 2 inches, and two wet film thickness gauges. Construct additional test strips when major equipment repairs or adjustments are made or when the traffic stripes are determined to be defective. Construct additional test strips when traffic striping operations are performed on multiple, non-continuous occasions. Perform additional test strips as requested by the RE. When the test strip is in compliance, as determined by the RE, proceed with striping operations. Each test strip may remain in place and become part of the finished stripes subject to the requirements of 610.03.01.E.

  4. Applying Striping. Mix epoxy resin with an automatic proportioning and mixing machine, and hot-spray the compound at a temperature of between 100 and 130 °F onto dry surfaces. Apply the compound with a wet film thickness of 20 ± 1 mil. Apply the material during dry weather conditions when the ambient temperature is a minimum of 45 °F and the surface temperature is a minimum of 50 °F. Adjust operations as required for the prevailing ambient and surface conditions to achieve a no-track drying time of 30 minutes or less.

    Immediately after, or in conjunction with, the compound application, uniformly apply 12 pounds of large glass beads per gallon of epoxy resin to the compound. After applying the large glass beads, uniformly apply 12 pounds of small glass beads per gallon of epoxy resin to the compound.

    Remove all compound that has been tracked or spilled outside of the intended placement areas.

  5. Performance. Ensure that the traffic Stripes, show no fading, lifting, cracking, chipping for any reason including but not limited to traffic wear, maintenance activities including snow plowing, until Acceptance. Ensure that 60 days after application, traffic stripes have a minimum retroreflectance value of:

    375 millicandelas per square meter per lux for white traffic stripe
    250 millicandelas per square meter per lux for yellow traffic stripe

  6. Defective work. Replace traffic stripes that are determined by the RE before Acceptance to be defective or that are damaged during construction. Remove defective stripes as specified in 610.03.08.

    Replace an entire 10-foot skip line if the RE determines the stripe to have a deficiency.

    If the RE determines, based upon calculated and measured yields, that the striping has a wet film thickness of less than 19 mils, restripe the entire length with 20 mils of new compound.

    Provide the RE with an LTL-X Reflectometer that has been certified by the manufacturer as being calibrated within the last two years.  The RE will test the retroreflectance of traffic stripes.  Replace traffic stripes that do not meet the retroreflectance values indicated in 610.03.01.E.  Replace the entire length of striping where improper curing or discoloration has occurred.  Discoloration is localized areas or patches of brown or grayish colored compound.  Where improper curing or discoloration occurs intermittently in intervals of 100 feet or less throughout the striping length, replace the entire length of striping from the beginning of the first occurrence until the end of the last occurrence, plus 5 feet on each end.

    Replace the entire length of striping that has failed to bond to the pavement, or has chipped or cracked. Where more than 25 spots of chipping, cracking, or poor bonding have occurred within 1000 linear feet of striping, replace the entire 1000 foot length of striping as indicated in 610.03.01.E.

  7. Opening to Traffic. Complete each application of all types of traffic stripes and allow to thoroughly dry before opening to traffic. At a minimum, delineate center lines on undivided roadways and broken lines between lanes before the traveled way is opened. The RE will determine when the traveled way can be opened to traffic.

610.03.02 Traffic Markings

  1. Marking Plan. At least 20 days before beginning the work, submit to the RE for approval a marking plan that includes:

    1. Schedule of operations for applying traffic markings,
    2. Number and type of equipment,
    3. Manufacturer’s recommendations for use of the materials, including mixing ratios and application temperatures.
    4. Details on the means and methods for surface preparation
    5. Details on the means and methods for premarking

  2. Surface Preparation. Immediately before marking the pavement surface, clean the surface of dirt, oil, grease, and foreign material, including curing compound on new concrete. Clean the surface 2 inches beyond the perimeter of the marking to be placed.

  3. Applying Traffic Markings. Place preformed thermoplastic or hot extruded thermoplastic traffic markings on thoroughly dry surfaces and during dry weather conditions. Apply using equipment and procedures that produce markings of the specified color, width, and thickness with well-defined edges, uniform retroreflectivity, and proper bonding to the pavement. Apply the thermoplastic material as follows:

    1. Preformed Thermoplastic. Melt the preformed thermoplastic tape to bond the traffic markings permanently in position according to the manufacturer’s recommendations.

      Meet the minimum initial retroreflectance value, as specified in 610.03.01.D for thermoplastic tape, by applying additional glass beads to the hot-wet material in a uniform pattern as necessary.

    2. Extruded Thermoplastic. Uniformly heat the thermoplastic material. When the ambient and surface temperatures are at least 50 °F, apply the melted material at a temperature of between 400 and 425 °F. Extrude the thermoplastic traffic markings on the HMA or concrete pavement ensuring a thickness of 90 ± 1 mils.

      Immediately after, or in conjunction with the thermoplastic extrusion, uniformly apply glass beads to the wet material at a minimum rate of 10 pounds per 100 square feet of markings. Apply glass beads by mechanical means only.

  4. Performance. Ensure that the traffic markings show no fading, lifting, cracking, chipping for any reason including but not limited to traffic wear, maintenance activities including snow plowing, until Acceptance. Ensure that 60 days after application, traffic markings have a minimum retroreflectance value of:

    375 millicandelas per square meter per lux for white traffic markings
    250 millicandelas per square meter per lux for yellow traffic markings

  5. Defective work. Replace thermoplastic traffic markings that are determined by the RE before Acceptance to be defective or that are damaged during construction. Remove defective markings as specified in 610.03.08

    Replace the entire area of thermoplastic traffic markings determined to be less than the required thickness, to have incorrect color or width, to have failed to bond to the pavement, or to have chipped or cracked. The minimum replacement area is an individual word or symbol, or for longitudinal lines the entire length from where the deficiency first occurs to where it no longer exists.

    The RE will determine initial retroreflectance as follows:

    Provide the RE with an LTL-X Reflectometer that has been certified by the manufacturer as being calibrated within the last two years. The RE will test the retroreflectance of traffic markings. Replace traffic markings that do not meet the retroreflectance values indicated in 610.03.02.D.

  6. Opening to Traffic. Complete each application of thermoplastic traffic markings and allow to thoroughly dry before opening to traffic. The RE will determine when the traveled way can be opened to traffic.

610.03.03 Raised Pavement Markers (RPM)

Lay out the locations of all RPMs before installing to ensure proper placement. Place RPMs as follows:

  1. Place RPMs on the travel lane side of solid paint lines at a distance of 2 inches from the near edge of the paint line to the near edge of the RPM.
  2. Place amber RPMs between double yellow paint lines when there is no conflict with a longitudinal joint.
  3. Place RPMs located along skip lines on the line’s longitudinal center axis and at the midpoint of the unpainted gap between each dash.
  4. When placing RPMs near longitudinal joints, place at least 2 inches from the joint.

Obtain RE approval of RPM locations before beginning sawcutting operations. If the pre-installation layout determines that a RPM is to be placed at a transverse joint or at a location that shows evidence of cracking, checking, spalling, or the failure of underlying base material, relocate the RPM longitudinally. Obtain RE approval of the proposed relocation. Ensure that the center-to-center RPM distance does not deviate from the specified distance by ±4 feet. If the center-to-center distance for the proposed relocation deviates from the specified center-to-center distance by ±4 feet, do not install the RPM.

When placing RPMs on bridge deck surfaces, locate reinforcement steel in the bridge decks using a pachometer. Do not place RPMs in any location that would expose the existing reinforcement steel. Repair damage to the reinforcement steel or bridge deck that is caused by the installation of RPMs.

Sawcut roadway grooves to the depth, width, and diameter specified by the RPM manufacturer. Sawcut only those grooves for RPMs that will be installed during the same workday.

Ensure that roadway grooves are free of dirt, dust, oil, grease, moisture, curing compounds, loose or unsound pavement, or other material that may interfere with bonding of the epoxy compound. Sand blast grooves where necessary. Ensure that the grooves are dry where installing RPMs.

Apply epoxy compound according to the manufacturer’s recommendations. Do not apply epoxy compound when either the pavement surface or ambient air temperature is less than 50 °F at the time of application.

Install RPMs according to the manufacturer’s recommendations. RPM leveling lugs shall rest on the pavement surface. Do not allow lugs to drop below the pavement surface. The tips of each RPM’s snow plow deflecting surface must remain below the roadway surface.

Use reflector adhesive to bond each RPM lens to its casting. The RE will reject a RPM if visible buildup of epoxy compound or reflector adhesive affects its optical performance.

610.03.04 Removal of RPMs

Remove RPMs as directed by the RE. Dispose of RPMs as specified in 201.03.09. If directed by the RE, fill the hole with HMA patch as specified in 159.03.07 except sawcutting is not required.

610.03.05 Removal and Replacement of RPM Lenses

Remove existing RPM lenses and install new mono-directional or bi-directional pavement reflector lenses using methods that do not damage the RPM castings.

Dispose of RPM lenses as specified in 201.03.09.

610.03.06 Ground Mounted Flexible Delineators

Use white retroreflective sheeting for delineators located on the right side when facing in the direction of traffic.  Use yellow retroreflective sheeting for delineators located on the left side when facing in the direction of traffic.

Drive ground mounted flexible delineators vertically into the ground to a minimum depth of 18 inches. Position flexible delineators so that the plane face of the center of the reflective area is at an angle of 0 degrees with a line that is perpendicular to the direction of traffic.

610.03.07 Rumble Strips

At least 20 days before constructing rumble strips, submit a plan for cutting rumble strips and debris collection/removal to the RE for approval.

Construct rumble strips on newly constructed pavement after it has cooled sufficiently to allow the cutting to be done cleanly without causing damage to the adjacent pavement.

Clean the area where rumble strips are to be constructed. Construct rumble strips by cutting indentations into the pavement perpendicular to the traveled way without disturbing the surrounding pavement. Collect cuttings and reuse or dispose of as specified in 202.03.07.

Ensure that the centerline rumble strips are constructed before placing TRAFFIC STRIPES. After cutting centerline rumble strips, ensure that the centerline TRAFFIC STRIPES are placed before opening the roadway to traffic.

610.03.08 Removal of Traffic Stripes and Markings

Remove traffic stripes and traffic markings using methods that do not damage the underlying or adjacent pavement, and do not cause gouging or create ridges or grooves in the pavement. Before beginning removal operations, demonstrate to the RE the proposed method to remove at least 95 percent of stripes or markings without removing more than 1/16 inch of pavement thickness. Obtain RE approval before beginning removal operations.

The removal area includes the area of the stripe or marking plus 1 inch on all sides. Only remove traffic stripes or markings that will be replaced during the same workday.

Dispose of debris from the removal of stripes and markings as specified in 201.03.09.
