摘要
针对沥青混合料的路用性能特点,以钢渣作为原材料,设计并制备出钢渣SM A沥青混合料。并在室内试验过程中,首先研究了钢渣的材料特性,并采用普通车辙试验检验混合料的高温稳定性;在IN STRON材料试验机进行混合料的低温性能与疲劳性能试验;通过测定钢渣与沥青之间的接触角值以及浸水车辙试验来评价钢渣SM A混合料的水稳定性。试验结果表明,钢渣可以作为沥青面层优质集料使用,设计并制备出的沥青混合料具有良好的路用性能。
According to the pavement performance of SMA mixture, the steel slag is used as raw material to design and manufacture steel slag SMA mixtures. In the test process, first, steel slag material performances are discussed, then by using traditional rutting test, the high temperature stability is tested; the tests of low temperature and fatigue performance of steel slag SMA mixt＇ures are performed on INSTRON tester; by measuring contact angle value between steel slag and asphalt binder and performing soaking wheel track test, water resistance performancs of this mixture are discussed. Test results show that the steel slag has good pavement performances and may be used as superior aggregates in SMA.
