摘    要:为了研究由钢渣、再生骨料制作的透水沥青混合料在冻融循环后的性能衰变规律,判断在季冻区将钢渣、再生骨料应用于透水沥青混合料的性能优劣,选择以玄武岩集料制作的马歇尔试件作为参照,通过肯塔堡飞散实验、低温劈裂实验和动态蠕变试验对以钢渣、再生骨料为粗集料成型的透水沥青混合料进行了研究。研究结果表明:由钢渣、再生骨料制作的透水沥青混合料在冻融循环后具有更好的高温抗车辙性,但低温抗裂性需要进一步提高。

关 键 词:钢渣  再生骨料  透水沥青混合料  冻融循环

Abstract:In order to study the performance of permeable asphalt mixtures made from steel slag and recycled aggregate after freeze-thaw cycles and explore the possibility of applying these two materials to pavement engineering in the seasonal frozen region, three sets of standard Marshall test pieces were prepared from basalt, steel slag and recycled aggregate as coarse aggregates. Then the mechanical properties of the three mixtures after freeze-thaw cycles were studied by Cantabro test, low temperature splitting test and dynamic creep test. The results showed that the permeable asphalt mixtures made from steel slag and recycled aggregate have better high temperature rutting resistance after freeze-thaw cycle, but low temperature crack resistance needs to be further improved.
Keywords:steel  slag recycled  aggregate permeable  asphalt mixture  freeze-thaw  cycles
