Abstract

To identify the effect of fatigue performance of large stone asphalt mixes (LSAM) for cement replacing mineral filler, first of all, 5 kinds of cement dosages, which is 20%, 40%, 60% 80% 100% were designed, and then tensile splitting fatigue strength tests were done on MTS. Results show that after using cement replacing mineral filler, the optimal asphalt amount has no change, and there is no obvious difference for the splitting fatigue properties of LSAM, so it is feasible for using cement to replace mineral filler for large stone asphalt mixes.
