Thermoplastic Traffic Striping Material,

Hydrocarbon Resin Binder, White and Lead-Free Yellow


This specification covers a hot-melt, retroreflective, Thermoplastic traffic marking material that is suitable for producing durable traffic stripes and pavement markings on Portland cement concrete or asphalt concrete pavements. This material is heated and applied to road surfaces in a molten state using a mechanical applicator. While still hot, reflectorizing Glass Beads are applied to the surface of the applied Thermoplastic striping material. Upon cooling to normal pavement temperatures this material shall produce durable, adherent, retroreflective traffic stripes and pavement markings that are capable of resisting deformation by traffic.


The following specifications, test methods and standards in effect on the opening date of the Invitation for Bid form a part of this specification where referenced.

3.1 Composition:

The Thermoplastic material shall be composed of 100% solids. The binder shall consist of synthetic hydrocarbon Thermoplastic resins which are homogeneously blended together with all necessary prime pigments, fillers, Glass Beads and additives to produce a traffic striping material that meets the requirements as specified herein. All Thermoplastic material shall be free from; lead, chromium, cadmium, barium and other toxic metals.

3.1.1 White Material:

White thermoplastic shall contain a minimum of 10% (by weight) of titanium dioxide pigment meeting ASTM D476 Type II (Rutile). The titanium dioxide content will be determined using ASTM Designations; D 4563, D 4764, D 5380 or other x-ray diffraction analysis method. White thermoplastic must meet the Retroreflectivity requirement when applied with drop-on Glass Beads.

This specification cancels and supercedes; specification #PTH-02HYDRO (February, 2006 and September , 2002), specification #8010-01B (March, 2000),

specification #8010-01A (July, 1997), specification #8010-01 (March, 1994) and specification #8010-21C-21 (March, 1992).

3.1.2 Lead-Free Yellow Material:

Lead-Free (L/F) yellow thermoplastic shall contain proper amounts of C.I. Pigment Yellow 83 (opaque version) and titanium dioxide (Rutile) to produce a yellow material that has a weather-fast and heat stable yellow color which meets the; Yellow Color, Reflectance, Color Stability (Accelerated Weathering) and Retroreflectivity requirements as stated herein. Other pigments may be added to achieve these color requirements. The L/F yellow thermoplastic material shall appear yellow during both daytime and nighttime conditions when applied with drop-on beads.

3.1.3 Other Ingredients:

The remainder of the thermoplastic composition shall be determined by the manufacturer - within the constraints of the requirements below. It shall be the manufacturer's responsibility to produce a thermoplastic material containing the necessary plasticizers, antioxidants, and other additives so that the thermoplastic will retain its color, viscosity and all other properties as specified herein. In addition to being essentially lead and chromium free, the thermoplastic shall not contain any hazardous materials at levels that would cause the thermoplastic to be classified as a hazardous waste under Title 22, Division 4, section 66261.20 of the California Code of Regulations.

3.2 Form:

The thermoplastic material shall be supplied in either block or granular form as requested in the purchase order.

3.3 Application Type/Viscosity:

Two viscosity grades of thermoplastic material shall be available for purchase; Extruded-Viscosity and Low-Viscosity. Extruded-Viscosity grade is more suitable for screed type applicators and thicker applications (+2.5mm), including recessed applications. Low-Viscosity grade material is commonly used with ribbon or spray type applicators. The thermoplastic material shall be formulated to meet the viscosity grade specified in the purchase order.

3.4 Characteristics of the Finished Thermoplastic:

Use California Test Method No. 423 (CTM 423) unless otherwise specified.
