Title: Effect of aggregate gradation on performance of asphalt mix at low temperature
Abstract: The effect of aggregate gradation on the performance of asphalt mix at low temperature is ignored longtime, and its evaluation methods are also in controversy. The effect of aggregate gradations on the property of asphalt mix was studied and the test methods evaluating the performance of asphalt mix at low temperature was probed. Several gradations were tested and evaluated, based on test results, the proper gradation of anti-cracking mixture was put forward. Through analyzing the mechanism of asphalt pavement cracking and test results, the shrinking character and flexibility of asphalt mix were thought as two main factor related to pavement cracking, the shrinking parameters and low-temperature stress were recommended to evaluate the performance of mix at low temperature.
