摘要
中国的高速公路沥青路面绝大多数采用半刚性基层沥青路面,为发展高速公路建设起到了重要作用。但采用一种沥青路面结构存在许多不足,不少高速公路沥青路面产生了耐久性差、使用寿命短的现象。文章分析了国际上多种路面结构在高速公路上的使用现状,介绍了我国开展的包括柔性基层、组合式基层在内的不同结构的沥青路面在高速公路上的应用情况。最后建议对沥青路面的设计进行完善,明确其适用范围,应推广采用组合式基层、柔性基层等其它路面结构。
Semi-rigid base is adopted in almost all expressways of asphalt pavement in China. Although this type of structure has played an important role in setting up China＇ s expressway system, there are disadvantages such as poor durability and short life. Several types of pavement structure applied in expressways in the world are analyzed in the article.Application of flexible and combined base in expressways of asphalt pavement in China is also introduced.
