摘要
节能环保、低碳施工是我国现阶段工程建设过程中积极倡导的施工工艺.为测试USP低温改性沥青混合料的使用性能,本研究对其马歇尔稳定度、残留稳定度、高温稳定性、冻融劈裂、劈裂强度、渗水性进行试验分析,结果显示,USP低温沥青混合料具有较好的抗水毁能力,掺入USP改性沥青能够提高沥青混合料的低温疲劳性能,改善沥青混合料抵抗外力破坏性能.
Our country actively advocates low carbon construction technology of energy-saving and environmentalprotection in the present stage. For testing the functional performance of USP low temperature properties of modifiedasphalt mixture,we analyzed its Marshall stability,residual stability,high temperature stability,freeze-thaw splitting,splitting strength,and water permeability. The results showed that USP asphalt mixture at low temperature has goodability to resist waterlogging,and when it mixed with USP modified bitumen can improve the fatigue performance ofasphalt mixture of low temperature,and the performance of asphalt mixture to resist external force damage.
