This standard practice provides a standardized procedure for preparing specimens of thermoplasticity pavement marking materials prior to performing various performance tests. This method ensures that the preparation of the samples is consistent with the raw materials, thus guaranteeing the accuracy of the test results. These test results can be used to verify that the thermoplasticity pavement marking materials meet the relevant specification requirements and to help manufacturers evaluate the conformity of different batches of materials. Although this standard does not address specific physical or chemical testing of thermoplasticity pavement marking materials, its standardized sample preparation process is important for material testing.
