阳茂高速公路沥青路面保护策略

阳茂高速公路是国道主干线(沈阳)至(海南)高速公路广东境内的一部分,于2004年年底建成通车。全长79.76km,双向四车道,设计速度为120km/h,全线均为沥青混凝土路面。该高速公路开通以来,路面综合状况良好,主要的问题是裂缝、唧浆、车辙以及横向力系数偏低未能达到养护规范要求。为了防止路面的进一步损坏,特别是防止由于路面表面功能的损坏引起路面结构性的损坏,提出了预防性养护的路面保护方案。该方案计划对于保持和改善沥青路面性能,延长路面使用寿命具有重要意义。

Protection for Yangmao Asphalt Pavement

Yangmao Expressway is part of the National Trunk Highway（Shenyang） to（Hainan） within Guangdong,was open to traffic in late 2004,which is as long as 79.76km,four-lane two-way,design speed of 120km/h and full length of asphalt concrete pavement.During the over two years of operation,Pavement has been kept in good conditions,however,there are the main problems,including cracks,jack pulp,rutting,and low lateral force factors,which failed to meet maintenance specifications.In order to prevent further damage to the pavement,especially to prevent damage to structural damage arising from pavement surface failure,the pavement protection program of preventive maintenance has been proposed.The program will play an important role in the maintaining and improving of the performance feature of asphalt pavement features of Yangmao Expressway and in the extension of pavement service life.
