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

Importancia y uso:

5.1 The method described in this practice provides a procedure to rapidly generate pavement marking samples in the laboratory, suitable for the testing of applied pavement marking properties.

5.2 This practice is intended to provide uniform laboratory pavement marking samples that reduce the variability associated with obtaining pavement marking samples in the field.

5.3 This practice is particularly useful for directly comparing applied pavement marking properties as impacted by variations in materials, film thickness, and drop-on particle application rates for quality control or development purposes.

5.4 This practice can be used in evaluating pavement marking materials formulated and produced in the laboratory and for drop-on particles specifically made and prepared in the laboratory. It can also be used for testing materials that are already manufactured and either stored as work-in-process or placed in its final packaging. When testing manufactured materials in the finished goods state, it is extremely important that a representative sample of the pavement marking material and the drop-on particles are obtained for use, in order to draw the proper conclusions from any testing done on pavement marking samples made from these materials. For proper sampling of thermoplastic pavement markings in a finished good state, it is recommended to follow Practices D7307 and D7308. For proper sampling of liquid pavement marking with both single and multicomponent materials, it is recommended to follow Practice D8008.
