This standard provides methods for analyzing the percentage of gluing agents and reverse reflection Optical inspection elements (e.g. Glass beads) or non-reverse reflection particles (e.g. Silica sand) in white and yellow thermal plasticity pavement marking materials. The analysis process includes further determination of the presence of titanium dioxide, lead chromate and organic pigments by ashing tests. The standard specifies procedures for weight analysis and indicates methods for the assessment of HCL insoluble particles, but does not include detailed measurement of titanium dioxide or lead chromate pigments. Users should pay attention to visual evaluation and reporting of particle types according to actual conditions.
