摘要
再生骨料沥青混凝土是将建筑垃圾再生骨料代替混凝土中的部分或全部骨料的普通沥青混凝土。通过浸水马歇尔试验和冻融劈裂试验对再生骨料沥青混凝土水稳性进行分析。结果表明,AC-16和AC-20浸水稳定度最高分别达到19.60、19.38 MPa,冻融劈裂强度比最高达到0.87,两者都能满足规范规定的要求,并且通过对试验数据分析找出建筑垃圾再生骨料代替原生骨料的对沥青混凝土水稳性影响的规律。
Recycled aggregate asphalt concrete was a kind of ordinary asphalt concrete which replaced part or all of aggregate in concrete with recycled aggregate of construction waste.In this paper,the water stability of recycled aggregate asphalt concrete were studied by immersion Marshall test and freeze-thaw splitting test.The results showed that the highest stability of AC-16 and AC-20 immersion Marshall was 19.60 and 19.38 MPa respectively,and the highest strength ratio of freeze-thaw splitting was 0.87.Both of them can meet the requirements of the code.The influence of recycled aggregate of construction waste instead of original aggregate on water stability of asphalt concrete was found out through the analysis of experimental data.
