摘　　要：对比规范所规定的沥青路面构造深度测试方法,评价各方法的优劣,进而探讨依靠平面图像灰度值推演得到空间图形深度的变化的机理,分析在该三维还原过程中存在的局限性,研究出更加可靠的数字图像处理办法,从而使图像法与铺砂法存在良好的相关性成为可能,并对道路工程人员提出操作上的建设性意见。By comparing the advantages and disadvantages of the methods that are regulated in asphalt pavement specifications, and exploring the mechanism of the process in which 3 D model can be achieved from gray value in 2D digital image and analyzing its limitations, a relatively dependable method is presented, which makes the image process correlates well with the conventional sand -spreading method. Highway engineering practitioners can get constructively process suggestion in this paper.
