本文以江苏某高速公路为例,针对现场施工工期紧、通车要求高等客观情况,提出采用连续配筋混凝土路面基层解决沥青路面基层出现的裂缝病害的方案。连续配筋混凝土与沥青路面相接处及与构造物相接处设置过渡段和锚固结构,并对过渡板块接缝的设置形式和填缝材料的技术指标提出了相应的要求。该方法的提出和应用为沥青路面基层裂缝病害的处理提供了及时有效的可操作方案,具有很强的现实指导作用。
In this paper, an expressway in Jiangsu Province is taken as an example. In view of the tight construction schedule and the open traffic requirement, a scheme to solve the cracks in the base course of asphalt pavement by using continuous reinforced concrete pavement base is proposed. The transitional section and anchoring structure are arranged between the continuous reinforced concrete and the asphalt pavement and at the junction with the structure, and the corresponding requirements are set for the setting forms of the transitional slab seams and the technical indicators of the caulking material. The proposed method and application of the grassroots crack for asphalt pavement treatment provides a timely and effective operation of the program, with a strong practical guidance.
