现场热再生技术在高速公路车辙处治中的应用探讨

Application of Field Heat Recycling Technology in Treatment of Expressway Rutting

针对江苏省某高速公路现场热再生车辙病害维修路段,分别从室内试验、现场质量抽检、经济和环境效益、养护后评估进行分析,结果表明,原路面沥青混合料可添加3%再生剂进行再生利用;养护后路面车辙得到了一定的改善,衰减速度一年后逐渐趋于缓慢,现场热再生技术可以有效处治路面的车辙,同时具有显著的经济效益和环境效益。

According to Jiangsu Province Expressway field heat recycling technology rutting maintenance sections respectively from the laboratory test, field quality sampling, economic and environmental benefits,conservation assessment were analyzed. The results show that the original pavement asphalt mixture can add 3 % regenerants were recycled; curing pavement rutting has been improved, decay rate a year tend to be slow, Field heat recycling technology can be effective treatment of pavement rutting depth; but also has remarkable economic and environmental benefits.
