The asphalt mixture AC-20C was compacted by standard method, and the physical and mechanical properties of asphalt concrete specimens were tested. In the test process, the difference of indirect tensile strength is investigated by using different loading rates, so as to evaluate the correlation between the test process and the test results of asphalt mix-ture. The test results show that: when the appropriate loading speed is adopted, the asphalt mixture test can achieve more ideal test results, and different test conditions will produce completely different results, so that the test data are completely distorted. Under the condition of excluding other factors, more real test data can be obtained, so the test should be carried out in strict accordance with the requirements of the specification.
