岩沥青在龙青高速中的应用

the Application of Rock Asphalt in Longqing Highway

龙口至青岛高速公路,地处北温带季风区域,夏季湿热多雨,具有湿度大、气温高等特点。路面性能必须满足较高的力学性能与强度。但面层结构层设计较薄,考虑到路面的力学性能与强度,为提高路用性能,采用岩沥青改性沥青作为路面胶结材料进行设计研究。结果表明:采用岩沥青设计的沥青混合料在力学性能与强度上表现优良,性能完全满足路用性能的要求。

Longkou to Qingdao expressway, is located in the north temperate monsoon zone, hot and hu- mid and rainy summer, have the characteristics of high humidity and high temperatures. Pavement perform- ance must meet the higher mechanical properties and strength. But with thin surface layer structure design, considering the mechanical properties and pavement strength, to improve the road performance, we use the rock rock fully asphalt modified asphalt as a cementing material for design research. The results show that the design of asphalt asphalt mixture on the mechanical properties and strength of excellent performance, performance meet the requirements of road performance.
