摘要
岩沥青改性剂与基质沥青具有优良的配伍性,但不同掺量的岩沥青对沥青混合料的力学性能影响很大。本研究以AC-13沥青混合料级配为基准,通过室内对比试验,对基质沥青混合料和不同掺量下的岩沥青改性沥青混合料的高温稳定性、低温抗裂性、水稳定性、疲劳耐久性等力学性能进行研究,以期为岩沥青改性沥青混合料的掺量标准提供参考。
The compatibility of rock asphalt modification agent and matrix asphalt was excellent,while different contents of the rock asphalt have great influence on the mechanics property of the mixture.Based on the aggregate grade of AC-13 mixture,the mechanical properties of the matrix asphalt mixtures and the rock asphalt mixtures with different quantities of rock asphalt were studied by laboratory tests,which included the high-temperature stability,low-temperature anti-cracking performance,water stability and fatigue resistance.This research could give a reference for the proper rock asphalt quantity of the mixture.
