摘要
本文分别对天然砂、石屑和机制砂作为细集料进行沥青混合料配合比设计,通过沥青混合料性能试验,得出机制砂相对于天然砂和石屑对沥青混合料的马歇尔稳定度影响不大,但有着更好的高温稳定性、水稳定性等优点。
In this paper,the mixture ratio of natural sand,stone chips and mechanical sand were designed respectively as fine aggregates.Through the performance test of asphalt mixture,it is concluded that mechanical sand has little effect on the Marshall stability of asphalt mixture compared with natural sand and stone chips,but has better high temperature stability and water stability.
