意义和目的
5.1 The function of the test method is to provide numerical instrumental results indicating the bond and/or bonding strength of the thermoplastic pavement marker with the specified cement brick substrate.

5.2 The use of this test method allows users and manufacturers to control the quality of the product and make inferences about the performance of thermoplastic pavement marking products. The results of these tests also provide useful information for the research and development of thermoplastic pavement marking materials.

5.3 This method has been revised to be more consistent with other ASTM coating bonding methods in test methods D4541, D5179 and D7234.

5.4 Strict adherence to the outlined procedures is necessary to test the accuracy of the method. In any case, bonding strength should not be accepted unless the method is complied with.
