1 施工前的准备工作施工前的准备工作主要有确定料源及进场材料的质量检验,机械选型与配套、拌和厂选址、修筑试验段等项工作。目前,我国高等级公路路面所用的沥青大部分从国外进口。对每批沥青进行抽样检测;确定石料场。另外,进厂的砂、石屑、矿粉均应满足规定的质量要求。拌和设备的生产能力应根据工程量和工期进行选择,并在施工前对各种施工机械进行全面检查。
1 Preparation before construction The preparation before construction mainly includes the work of determining the quality of incoming materials and incoming materials, mechanical selection and matching, site selection of blending plants and construction of test sections. At present, most of the asphalt used in high-grade highway pavement in our country is imported from abroad. Sampling and testing of each batch of asphalt; determine the stone field. In addition, into the plant sand, stone chips, slag should meet the required quality requirements. Mixing equipment production capacity should be based on the project volume and duration to choose, and before construction of a variety of construction machinery to conduct a comprehensive inspection.
