Study on High Temperature Performance of Asphalt Mixture Based on Rutting Test

Article Preview

Abstract:

In order to deeply reveal the high temperature stability of asphalt mixture, rutting test was implemented to evaluate the high temperature stability of asphalt mixture, and the evaluation index is dynamic stability. The effect of asphalt type, degree of compaction, gradation type and nominal maximum aggregate size on rutting test results was studied respectively. The results showed that: modified asphalt can improve the high temperature stability of asphalt mixture effectively; the anti-rutting performance of asphalt mixture reduces gradually with decrease of the degree of compaction; the anti-rutting performance of SAC-16 is greater than that of AC-16; and the anti-rutting performance of asphalt mixture is improved with increase of the nominal size of aggregate.
