摘要
濮鹤高速公路自2004年底建成通车以来,经过7年多的正常运行,沥青混凝土路面已经出现了诸如横缝、纵缝、龟裂等早期病害。为了防止雨水通过裂缝渗入路面基层,对道路造成进一步损害,濮鹤高速公路积极引进国外新材料进行路面早期病害处理探索,通过应用JB环氧沥青新材料处理路面早期病害,有效解决了病害路面防水问题,提高了道路安全性能和服务品质。
Since the Pu-He expressway opened to traffic at the end of 2004,after over 7 years nor- mal operation, there have been of early diseases of pavement such as transverse crack, longitudinal crack and map crack etc. In order to prevent the rain through the crack into the pavement grassroots,to cause additional damage of expressway, Pu-He expressway actively introduce foreign new materials to explore processing to the early diseases of pavement, and employed the JB epoxy asphalt processing to early disea- ses of pavement, resolved the waterproof problem of pavement, improved the expressway safety perform- ance and service quality.
