摘　　要：随着我国农村公路路面使用频率和荷载要求的不断提高,许多水泥路面出现了裂缝等一系列病害,影响公路的正常使用,故急需对农村公路进行提升改造。现结合超薄沥青罩面在义乌上岭线水泥路面提升改造工程中的应用,提出了适合农村水泥路面的超薄沥青混合料的配合比,确定了该超薄沥青罩面的组合结构及施工工艺,验证了超薄沥青罩面在农村水泥路面“白改黑”改造工程中的适应性。With the continuous increase in traffic frequency and load requirements of rural road pavements in China,various diseases such as cracks have appeared in many cement pavements,which affect the normal use of roads,making urgent upgrade of rural roads.Based on the application of ultra-thin asphalt overlays in the cement pavement upgrading project of Shangling Line in Yiwu,this paper proposes the gradation of ultra-thin asphalt mixture suitable for rural cement pavements,determines the appropriate combination structure and construction technology suitable for rural cement pavements,and verifies the adaptability of ultra-thin asphalt overlays in the rural cement pavement"white to black"transformation project.
