酸性花岗岩沥青混合料水稳性试验
Experiment on water stability of acid granite asphalt mixture
摘要
Abstract
In order to improve the long-term water stability performance of granite asphalt mixture in high humid and hot areas,3%cement,4%cement,and 30%hydrated lime water are sequentially added for soaking treat-ment.The long-term applicability and water stability performance of acidic granite asphalt mixture are evaluated through freeze-thaw and freeze-thaw drying cycle splitting tests,and compared and analyzed with untreated acid-ic granite asphalt mixture.The results show that the splitting strength and the ratio of splitting strength of the acid granite asphalt mixture under the three test conditions decrease with the increase of freeze-thaw and freeze-thaw drying times.Among them,4%cement>3%cement>30%sluice water>untreated aggregate under freeze-thaw cycle condition.Under the condition of freeze-thaw drying cycle,4%cement>3%cement>30%sluice water>untreated aggregate.关键词
