Abstract
Through the freeze-thaw splitting test, rutting test, low temperature bending test, comprehensive analysis the affect of coarse and fine ratio on ATB asphalt mixture performance. The results showed that: the ratio of change have a significant effect on water stability, high temperature stability, low temperature stability. Reasonable coarse and fine ratio have a higher degree of stability; Smaller coarse and fine ratio can effectively improve the asphalt mixture water stable performance, with coarse and fine ratio increased, freeze-thaw splitting strength ratio decreases; Larger coarse and fine ratio have an adverse effect on the high temperature stability, dynamic stability after the first increase and then decrease with increasing coarse and fine ratio; Smaller coarse and fine ratio can significantly improve the low temperature stability.
