Abstract: In order to overcome the problems of long test time and large error existing in traditional methods, a new test method for low temperature crack resistance of toughened epoxy asphalt mixture is designed in this paper. This method is mainly based on the results of low-temperature performance of epoxy asphalt mixture, combined with grey theory to analyse the correlation of epoxy asphalt content, different sieve pass rate and low-temperature performance index, so as to obtain the relationship between different influencing factors and the low-temperature crack resistance performance index of epoxy asphalt mixture, and obtain the test results according to the relationship analysis results. The experimental results show that the method has the advantages of short test time, low error and reliability, and can be further applied in practice.

Keywords: toughened; epoxy asphalt; mixture; low-temperature crack resistance; test.
