ASTM D4796-17 PDF Download

The ASTM D4796-17 standard is designed to determine the cohesive and/or adhesive bond strength of thermoplastic pavement markings to a specified cement brick substrate. The goal of this test method is to provide numerical instrumental results that can be used to control product quality and make inferences about the performance of thermoplastic pavement marking materials. The results obtained from this test method can also be useful for research and development purposes in the field of thermoplastic pavement marking materials.

The revision of this method was done to ensure consistency with other ASTM bond methods for coatings, as outlined in Test Methods D4541, D5179, and D7234. It is important to strictly adhere to the procedures outlined in the standard to ensure precision of the test method. The bond strength should not be accepted unless there is conformance to the method.
