    Abstract

    This specification covers 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. It deals with longitudinal applications in non snow plow areas, standard (non-profile) pavement marking applications, and applications on smooth asphalt or concrete surfaces. It does not include asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish. This specification establishes requirements with respect to chemical composition and physical property 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 material application requirements.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 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.

    1.1.1 This specification is limited to:

    1.1.1.1 Longitudinal applications in non snow plow areas,

    1.1.1.2 Standard (non-profile) pavement marking applications, and

    1.1.1.3 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.

    1.1.2 This specification includes:

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

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

    1.1.2.3 Field performance requirements for the installed thermoplastic pavement markings, and

    1.1.2.4 Material application requirements.

    1.2 The values stated in inch-pounds units are to be regarded as the standard except where noted in the document. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
