806 - DURABLE PAVEMENT MARKING
800-27 Before mixing the components of the pavement marking material, heat the individual components to the
temperature ranges recommended by the manufacturer of the material. Do not excee d the maximum recommended temperature at any time. Apply the epoxy liquid pavement marking material at a thickness of 20-25 mils on all pavement. Immediately apply all glass beads (double drop system or blended bead) to the epoxy liquid pavement marking at the glass bead gradation and bead drop rate recommended by the manufacturer to obtain the required level of retroreflectivity.
d.Multi-Component Liquid Pavement Marking. When pavement markings are applied to PCCP (including concrete bridge decks) less than 1 year old, remove all curing compounds and laitance by shot, sand or waterblasting. For intersection grade multi-component, grind the inset 15 mil (+10 mil tolerance) deep, with the width and length of the inset a maximum of 2 inches greater than the dimensions of the pavement marking on concrete surfaces. Multi-component liquid pavement mark ing will only be allowed for use on concrete pavement on a pre- qualified basis. Apply the multi-component liqui d material closely behind th e surface cleaning procedures. temperature ranges recommended by the manufacturer of the material. Do not excee d the maximum recommended temperature at any time. Apply the multi-component liquid pa vement marking material at the thickness of 20-25 mils on all pavement. Immediately apply the glass beads (double drop system or blended drop) to the multi-component liquid pavement marking at the glass bead gradation and bead drop rate recommended by the manufacturer to obtain the required level of retroreflectivity.
e.Intersection Grade Pavement Marking.
1.Multi-Component. Follow subsection 806.3d .
2.High Durability Tape. Grind an inset for the pavement marking into the surface of the pavement. Grind the inset 80 mil (+10 mil tolerance) deep with the width and length of the inset a maximum of 2 inches greater than the dimensions of the pavement marking. Apply adhesive-sealer primer of a type recommended by the manufacturer. Primer is required on all tape applications regardless of temperature, date or season. On new or existing PCCP, cut the marking tape on either side of any joint in the pavement that is crossed by the tape.
3.Preformed Thermoplastic. Grind the inset 40 mil (+ 20 mil tolerance) deep with the width and length of the inset a maximum of 2 inches greater than the dimensions of the pavement marking on concrete surfaces. Use a heating device recommended by the material manufacturer to fuse the preformed thermoplastic to the pavement. Apply adhesive-sealer primer of a type recommended by the manufacturer. Primer is required on all preformed applications on concrete regardless of temperature, date or season. Apply the pavement markings as recommended by the manufacturer.
f.All Thermoplastic Pavement Marking. The Engineer will verify the thickness of the thermoplastic pavement marking. Thickness will be checked by placing me tal plates or other suitable material of known thickness in a 3-foot section along the path of application at 2 to 3 locations. After the application of the thermoplastic material, the samples will be cut free. The material thic kness will be measured using either a micrometer or vernier calipers (with proper correctio n for the metal plate). The thickness reco rded for the locations within the 3-foot section will be averaged. Initially, thic kness determinations will be made every ⅓ mile for each color and each stripe width. Once a pattern of compliance is established, the Engineer may reduce the frequency of thickness verification to once each 1 mile section. Failure of a sec tion will require testing to return to the initial frequency until compliance may be re-established. The location of the 3-foot sample segment within the sample section will be selected at random. The Contractor may provide other devices for gauging thickness to the Engineer for approval. Apply thermoplastic pavement markings between April 15 and October 15. If the manufacturer’s recommendations allow, the Engineer may waive the date re strictions. The Engineer will notify the Contractor in writing of any allowed variance.
1.Thermoplastic Pavement Marking. The required thickness for longitudinal markings is a minimum of 90 mil at the edges, and a maximum of 125 mil at the cente r of the stripe. The required thickness for transverse markings and symbols is a minimum of 90 mil at the edges, and a maximum of 140 mil at the center. 806 - DURABLE PAVEMENT MARKING
800-28 For transverse markings on concrete, grind the inse t 40 mil (+20 mil tolerance) deep, with the width and
length of the inset a maximum of 2 inches greater than the dimensions of the pavement marking on concrete surfaces. Apply the binder-sealer according to the manufacturer ’s recommendations. Primer is required on all transverse applications on concrete regardless of temperat ure, date or season. The Engineer will not approve the application of the thermoplastic material until the binder-seal er applied to the pavement is devoid of all solvent or water. Apply prepared thermoplastic material in a molten stat e within a temperature range of 400 to 440ºF. The Engineer will not approve the use of scorched material or prepared material that has been maintained at 440ºF for a period exceeding 4 hours. Apply glass beads (double drop system or blended bead) to the thermoplastic pavement marking at the glass bead gradation and bead drop rate recommended by the manufacturer to obtain the required level of retroreflectivity.
g.Leading/Trailing Configuration. Installation of leading/trailing pavement markings may be used for intermittent markings on concrete or asphalt surfaces . The trailing (black) pavement marking shall be placed concurrently to the white pavement marking line when applied to the roadway. Apply black, opaque coal slag (20-40 mixture) to the trailing pavement marking line at a rate of 8-10 pounds per gallon of liquid pavement marking to achieve a skid resistance value of 50 BPN. Apply leading/trailing pavement mark ings that follow the same space conf iguration as broken lines, dotted extension and lane drop markings in the Contract Documents. 806.4 MEASUREMENT AND PAYMENT The Engineer will measure the various widths and colors or pavement markings by the linear foot. When the Contract Documents specify that the contrast pavement markings are installed in a leading/trailing configuration, the Engineer will measure the black pavement marking and wh ite pavement marking separately by the linear foot. The Engineer will measure each symbol. The Engineer will pay for 90% of the completed quantity for each of th e various widths and colors of pavement marking and symbols. Upon acceptance of the pavement markings following the 180 day observation period, the Engineer will pay for the remaining 10% of the completed quantity for each of the various widths and colors of pavement marking and symbols. When necessary, removal of permanent pavement markings will be measured and paid for under SECTION 808 . Removal of temporary pavement markings is subsidiary to the temporary pavement marking item. Payment for "Pavement Marking" an d "Pavement Marking Symbol" at th e contract unit prices is full compensation for th e specified work. Pay adjustments for width and retr oreflectivity deficiencies (see TABLES 806-3 and 4) will be entered on the Contractor’s Payment Vouchers (intermediate and final) under the bid item Contract Deduct.

800-30 Section 807
PAINTED PAVEMENT MARKING 807.1 DESCRIPTION Apply pavement markings as shown in the Contract Documents. B I D I T E M S U N I T S Pavement Marking (Paint) (*) (**) Linear Foot Pavement Marking Symbol (Paint) (White) (***) Each * Color ** Width *** Type of Symbol 807.2 MATERIALS Provide paint that complies with SECTION 2200 . 807.3 CONSTRUCTION REQUIREMENTS
a.Equipment. Use self-propelled or truck-mounted equipm ent designed for the purpose of applying painted pavement markings of the type, width and thickness required. Hand application or towing of the equipment will be allowed for smaller areas as approved by the Engineer. E quip the machine with an adjustable guide-on to obtain proper placement of the line.
b.Contractor’s Personnel. Provide a minimum of 1 employee on the project holding an American Traffic Safety Services Association (ATSSA) pavement marking certification and experienced in the application of the appropriate type of pavement marking material.
c.Surface Preparation. On existing pavements, remove the existing pavement markings according to
Division 808 — and the recommendations of the manufacturer of the new painted pavement markings.
Remove temporary pavement markings, if any, the same day the painted pavement markings are applied. Remove loose particles, dirt, tar, grease, residue of prior pavement markings and other deleterious material from the pavement surfaces as a result of surface preparation.
d.Alignment. Lay out the pavement marking as detailed in the Contract Documents. If the Contract Documents do not provide details, submit a layout plan for the pavement markings to the Engineer for approval. Locate longitudinal pavement marking stripes a minimum of 2 inches and a maximum of 8 inches from longitudinal joints. Provide adequate guide marks (approximately 2 inches by 1 foot at approximately 50-foot intervals) for the application of the pavement markings.
e.Pavement Marking Application. Provide the Engineer with a copy of the manufacturer’s application instructions. Apply paint according to the manufacturer’s recommendations. Apply paint at a wet film thickness of 18 mils at an approximate rate of 3.8 gallons per 1,000-foot for 4-inch solid line, and 0.95 gallons per 1,000-foot for 4-inch broken line. For other widths of marking, increase the am ount of paint proportionally. Apply glass beads to the painted line at a rate of 12 pounds of glass beads for each gallon of paint. Use an automatic bead dispenser attached to the striping machine in such a manner that the beads are dispensed almost instantaneously upon the line as it is being installed. Equip the glass bead dispenser with an automatic cut-off control synchronized with the cut-off of the paint. Keep traffic from crossing the newly applied lines by coning off the lines until the lines are dry to no-pick- up. The Contractor may reduce or elimin ate the need for this by using fast dr y paints and approved traffic control. Do not apply the paint when the air temperature is be low 40ºF, upon damp or frosted surfaces, or when, in the opinion of the Engineer, conditions are not satisfactory for the work. 807 - PAINTED PAVEMENT MARKING
800-31 f. Replacement of Unsatisf actory Pavement Marking. Apply pavement markings straight and close to
the intended alignment w ithout abrupt changes that result in an unacceptab le appearance. Lines that deviate laterally from the intended alignment more than 2 inches in 200 feet may be rejected. Remove and replace pavement markings that have: drag marks, gashes, gouges, foreign covering, discolored areas, areas that have failed to solidify, improper adhesion, improper width, length or thickness, areas that present a ragged appearance, areas that do not present sharply defined edges, areas with abrupt unintended changes in alignment. Do not meet TABLE 807-1 . TABLE 807-1: PAINTED PAVEMENT MARKING MINIMUM RETROREFLECTIVITY REQUIREMENTS TYPE OF MATERIAL COLOR millicandelas/sq m/lux* (minimum) (Initial) Waterborne Traffic Paint White 250 Yellow 175 NOTE: Provide an acceptable 100-foot retrorefle ctometer to use on the project which will remain the property of the Contractor. In the presence of the Engineer, measure the retroreflectivity between 12 hours and 7 days after the applicati on of all pavement markings. Take a minimum of 5 randomly sp aced readings per color line every 1 mile. The Engineer will average all of the readings for each color line within the 1 mile section to determine the retroreflectivity. Removal and replacement of unsatisfactory pavement marking will be at the Contractor’s expense. 807.4 MEASUREMENT AND PAYMENT The Engineer will measure the painted pavement marking by the linear foot for the various widths and classes. The Engineer will measure each symbol. Payment for "Pavement Marking (Paint)" and "Pavemen t Marking Symbol (Paint) (W hite)" at the contract unit prices will be full compen sation for the specified work.
