625.1Description
1 Furnish and place permanent pavement markings according to the Contract documents and the Manual on Uniform Traffic Control Devices (MUTCD). 2 The work also includes the determination of passing/no passing zones on two lane facilities according to the MUTCD where existing passing/no passing zones have not been established. Provide the Department with data used in establishing passing/no passing zones.
625.2Materials
625.2.1 Permanent Pavement Marking Materials 1 Use one of three binder materials — thermoplastic, fast cure epoxy, or polyurea. Apply thermoplastic or fast cure epoxy markings that meet the binder material requirements of Section 626 and Section 627. Apply polyurea pavement marking materials from the following approved suppliers — Epoplex - LS 90, 3M - Stamark LPM Series 5000, or other manufacturer’s materials under project specific, conditional approval.
625.2.2 Drop -on Glass Beads 1 Use drop- on glass beads for thermoplastic and fast cure epoxy markings meeting the material requirements of Sections 626 and 627 for AASHTO Type I beads. Use drop- on glass beads for polyurea pavement markings that comply with Section 626 for AASHTO Type I beads. 2 In addition, comply with the following material requirements for AASHTO Type I beads: • Ensure that drop- on glass beads contain less than 200 ppm (total) arsenic, 200 ppm (total) antimony, or 200 ppm (total) lead when tested to EPA Methods 3052 and 6010B. • Ensure that 20% by volume of the Type I drop on glass beads have a refractive index of 1.9 or greater. The beads may be applied to the permanent marking in a uniform blend or using a double drop application. 3 Ensure that all beads have the appropriate performance enhancing coatings recommended by the bead manufacturer for the type of binder material selected.
