摘　　要：我国西部严酷地区气候干燥,风沙多,温差大,日照长,紫外线强,道面混凝土施工时表面失水快,做面、拉毛困难,容易出现裂纹、裂缝。在分析早期裂纹产生原因的基础上,从原材料选择、混凝土配合比设计、施工工艺过程和时间节点等方面,提出了相应的关键技术要求和措施,配制并铺筑强度储备高、表面品质好、预期使用寿命长的高性能混凝土道面。In inclement West China, with the dry climate, much of sand and wind, high difference in temperature, the long sunlight and strong ultraviolet radiation, the surface evaporation of pavement concrete is great in construction, and the early crack appears likely and deals with the surface difficultly. Based on the analysis of the cause of the early crack, this paper puts forward the key construction technology and measures in the aspect of the material choice, concrete mix proportion design, construction process and time control to make and pave high strength, good roughness, long-life highperformance concrete pavement.
