针对甘肃省河西戈壁地区气温高、温差大、高温持续时间长的气候条件以及重车超载所导致的路面车辙状况,采用微表处和面层挖补相结合的技术,对沥青路面形成的压密性车辙和失稳性车辙进行了处治,高温期运营两年后,检测结果表明处治后的路段车辙均小于40mm,采用MS-4型微表处填充和路面挖补技术相结合的车辙处治方案可有效解决河西戈壁地区车辙问题,提高路面行车的安全性。 Aiming at the climatic conditions of high temperature, large temperature difference and long duration of high temperature in the Gobi region of Hexi, Gansu Province, and the rut conditions of the pavement caused by heavy vehicles overloading, a micro-surfacing and surface digging combined technique is applied to compaction of asphalt pavement Rutting and instability rutting were treated two years later, the test results show that after the treatment of the road rut are less than 40mm, the use of MS-4-type micro-surface filling and road excavation technology combined rutting treatment program can be Effectively solve the problem of rutting in the Gobi area of ​​Hexi and improve the safety of road traffic.
