Standard Specification for Thermoplastic Pavement Markings in Non Snow Plow Areas
 N D7942

Annotation

This specification covers a reflectorized thermoplastic based pavement striping material of the class that is applied to the road surface in a molten state by screed/extrusion or ribbon extrusion means. Retroreflectivity of the pavement marking compound is achieved initially by surface application of retroreflective optics at the time of pavement marking application. Upon cooling to normal pavement temperature, the pavement marking material produces an adherent reflectorized stripe of specified thickness and width capable of resisting deformation by traffic. The pavement marking compound includes retroreflective optics (glass beads or composite optics, or both) that are incorporated into the material at the time of manufacture that provide retroreflective properties during the service life of the material.

This specification is limited to:

Longitudinal applications in non snow plow areas,

Standard (non-profile) pavement marking applications, and

Applications on smooth asphalt or concrete surfaces. Asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish, are excluded from this specification.

This specification includes:

Compositional and physical property requirements of the thermoplastic pavement marking material,

Requirements for the optics that are used to reflectorize the thermoplastic pavement marking material after application,

Field performance requirements for the installed thermoplastic pavement markings, and
