| Abstract: | To research the effects of asphalt mixes fatigue performance caused by the new material,the stress distribution of the normal and complex beams by finite element analysis were contrasted and analyzed in this paper.Then designed and finished indoor flexural tensile fatigue tests through which the fatigue lives of the beams in different conditions were got and the fatigue equations were formulated by regression analysis.It was resulted that polymer modified cement based composite material played obvious improvement on asphalt mixes fatigue performance. |
