就地热再生整形工艺处治沥青路面车辙病害

Treatment of Asphalt Pavement Rutting Disease with Shaping Technology Hot in-Place Recycling

针对某公路沥青路面车辙病害,对原路面进行了分析评价。对比整形工艺和复拌工艺再生后沥青混合料的试验,发现整形工艺再生后的动稳定度、残留稳定度和残留强度比更高,故采用整形工艺就地热再生技术。通车一年后回访发现,整形工艺处置车辙病害,效果良好。

Aiming at the rutting disease of a highway asphalt pavement,the original pavement is analyzed and evaluated.By comparing the test of the recycled asphalt mixture with the reshaping process and the re-mixing process,it is found that the dynamic stability,residual stability and residual strength ratio of the recycled asphalt mixture with the reshaping process are higher,so the reshaping process is used for geothermal regeneration.A year after the opening of the vehicle,a return visit found that the reshaping process had a good effect in treating the rut disease.
