Standard Practice for Making a Laboratory Pavement Marking Sample Using a Pavement Marking and Drop-on Particles

active, Most Current
Publication Date: 1 November 2021
Status: active
Page Count: 15
scope:

This practice covers a procedure and apparatus for producing a representative laboratory pavement marking sample by applying a pavement marking material onto a suitable substrate, followed immediately with an application of drop-on particles consisting of retroreflective optics or other functional particles such as skid resistance particles suitable for laboratory testing or display. Examples of pavement marking materials appropriate for this practice would include waterborne traffic paint, solvent borne traffic paint, and plural component pavement markings such as epoxy, modified epoxy, polyurea, methyl methacrylate, and thermoplastic pavement markings. Plural component materials with extremely fast gel times might not be appropriate for this practice because the material gels too quickly to allow proper embedment of the drop-on particles.

The finished sample will consist of a pavement marking material applied in a liquid state to a sample substrate at the prescribed film thickness, with drop-on particles applied at the prescribed drop rate and embedment level on the surface of the pavement marking material, and then properly cured. The drop-on particles may consist of retroreflective optics such as glass beads or composite optics, or non-retroreflective particles such as skid resistant particles, or several of these items in combination.

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

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
