摘　　要：随着公路路面使用年限的增长,以及交通量剧增,开裂、车辙、坑槽等路面病害频繁出现。为了改善沥青路面的使用性能,确保行车安全,在修复开裂、坑槽等病害的同时,还要确保一定的平整度和抗滑性能。以广惠高速公路为例,采用UTAC薄层罩面技术对路面进行处治,并对施工后的路面质量进行检测。检测结果表明,UTAC薄层罩面技术可明显改善路面性能。Withincrease of service life of highway pavement and increasing traffic volume,cracks,rutting,potholes and other diseases have appeared more frequently.To improve the performance of asphalt pavement and ensure driving safety,when repairing cracks,pits and other diseases,it is also necessary to ensure a certain level of flatness and anti-skid performance.Taking Guanghui Expressway as an example,the UTAC thin-layer overlay technology has been used to treat the road surface,and the quality of the road surface after construction has been tested.The test results have shown that UTAC thin-layer overlay technology can significantly improve road performance.
