城市道路旧沥青路面加铺设计探讨

Discussion on Overlaying Design of Old Asphalt Pavement of Urban Road

对旧沥青路面进行加铺设计,应对现有路面状况进行调查评定。其存在病害的,应根据病害的成因、类型和严重程度进行处治。城市道路由于处于城镇内,交通特性、服务对象及建设条件等具有与公路不同的特点,城市道路应根据自身的特点进行加铺补强设计,确定适宜的加铺厚度、加铺类型、结构组合及材料。

The overlaying design of old asphalt pavement is carried out.The existing pavement conditions should be surveyed and evaluated.The pavements if with the diseases should be treated according to the causes,types and severities of the diseases.The traffic characteristics,service objects and construction conditions of urban road within city are different from a highway.The urban road should be designed of overlaying reinforcement according to its own characteristics.The suitable overlaying thickness,overlaying type,structural composition and material are determined.
