比较于传统的柔性路面,半刚性基层沥青路面有着成因和维修方面极其不同的特点。探讨了半刚性基层沥青路面的具体成因及其典型的病害特征,论述了路面维修与处理的有效途径。半刚性基层沥青路面具有与传统柔性路面完全不同的结构特征,同时,由于沥青材质本身的差异,以及受设计和施工水平的影响,沥青路面常常出现开裂、泛油、松散、坑槽等常见病害,这些病害的出现严重影响了行车速度、行车安全,加大了汽车磨损,缩短了沥青路面使用寿命,影响了道路投资效益。
Compared with the traditional flexible pavement, the semi-rigid base asphalt pavement is characterized by extremely different causes and maintenance. The specific causes of formation of semi - rigid base asphalt pavement and its typical disease characteristics are discussed. The effective ways of pavement maintenance and treatment are discussed. Semi-rigid base asphalt pavement has completely different structural characteristics from traditional flexible pavement. At the same time, due to the difference of asphalt material itself and the influence of design and construction level, common defects such as cracking, oil flooding, loose pit and pit groove often appear on asphalt pavement The emergence of these diseases seriously affected the driving speed, traffic safety, increased vehicle wear and tear, shortening the service life of asphalt pavement, affecting the road investment efficiency.
