This specification covers hot-sprayed, hot-extruded, ribbon gun, and preformed thermoplastic compound for pavement markings on asphalt or portland cement concrete pavement. Thermoplastic marking material shall consist of an alkyd based formulation. Non-preformed material shall be manufactured so as to be applied by spray 40 mils thick or extrusion 90 mils thick or greater to pavement in molten form, with internal and surface application of glass spheres, and upon cooling to normal pavement temperature, shall produce an adherent, reflectorized pavement marking of specified thickness and width, capable of resisting deformation. Black thermoplastic pavement markings shall require skid-resistant filler in lieu of glass beads. Black thermoplastic pavement markings shall have identical material properties to their white thermoplastic counterparts with the exception of color. For yellow thermoplastic material, the type and amount of yellow pigmentshall be at the option of the manufacturer, providing all other requirements of this specification are met. However, the pigment for yellow thermoplastic shall be lead free and shall meet the regulatory level of nonhazardous waste as defined by 40 CFR 261.24 when tested in accordance with EPA Method 1311, Toxicity Characteristics Leaching Procedures. The manufacturer shall provide certification that the material provided meets these requirements. .

This work consists of furnishing properly distributed asphalt material followed by a uniform application of aggregate for building a riding surface, improving the surface friction of a roadway, sealing cracks in the roadway, reducing the rate of oxidation of a surface mixture, or as an interlayer to delay or reduce the occurrence of reflective cracking. Asphalt Surface Treatment (AST), sometimes referred to as "chip seal," consists of a specified emulsion applied "cold" or polymer modified asphalt material applied "hot," at the temperature range specified in Table 507-1 for cold applications or Table 507-2 for hot applications, respectively. The application rates of asphalt material and aggregates will vary with aggregate size and existing roadway conditions but, for bid purposes only, shall meet the requirements of Table 507-1 or Table 507-2. The Project Engineer will review the actual application rates. Remove asphalt concrete surfacing by milling in accordance with these specifications and in conformity with the average depth, width, grade, cross-slope and typical sections shown on the plans or as established.
