近些年来,随着公路建设的发展,公路的改建和扩建工程越来越多,在旧水泥混凝土路面上加铺沥青面层是一种常用的、有效的路面修复技术。它具有工期短、对交通影响小、修复后路面服务性能好等优点,国内有相当多的公路采用了此类改造方案。 In recent years, with the development of highway construction, more and more road reconstruction and expansion projects are taking place. It is a commonly used and effective road repair technique to apply asphalt surface to the old cement concrete pavement. It has the advantages of short construction period, little impact on traffic and good service performance of the repaired pavement. There are quite a few domestic roads that adopt this kind of transformation plan.
