我局养护干线沥青公路逾800km,大部分是六七十年代修建的。超期“服役”,路面严重老化,因缺乏资金暂时难以进行改建。针对这种情况,公路局工程技术人员共商实施方案。经过几年的实践,探索出老沥青路在不中断交通的情况下进行维护的几种方法使全区干线沥青路面公路畅通无阻,为促进沂蒙山区经济发展提供了良好的运输环境。1 路基补强法经弯沉仪测量表明路基强度较差、路面
Our bureau maintains a trunk highway over 800km, most of which was built in the 1960s and 1970s. Extended “service”, the road serious aging, due to lack of funds temporarily difficult to rebuild. In response to this situation, Highway Bureau engineers and technicians to discuss the implementation plan. After several years of practice, several ways of maintaining the old asphalt road without interruption of traffic have been explored, which have provided a good transportation environment for the economic development of Yimeng Mountain. 1 subgrade reinforcement method by deflection measurements show that the subgrade strength is poor, the road
