摘要
为解决地震造成路面开裂形成水下渗,对路面、基层及路基水损害的问题,主要通过灌缝的方式对路面开裂给予修补。文章阐述了磷矿粉乳化沥青灌缝料的制作、施工工艺和性能,其粘结强度路用性能比较优良,满足水泥混凝土路面用沥青灌缝材料的要求。该灌缝料造价低,并且存储、运输和施工方便。
The earthquake makes the pavements crack and forms water infiltration, which can cause the water damages to the roads, substratum and roadbeds. In order to solve these problems, the means of cementation of fissures is applied to repair the cracking pavement. In the paper, the production, construction technology and properties of the caulking materials made by powdered rock phosphate emulsified asphait are elaborated. This material has good pavement functions such as the bonding strength, and can meets the requirement for emulsified asphait caulking material applied in cement concrete pave- ment. The cost on the materials is very competitive, and it is convenient for storing, transporting and constructing.
