摘　　要：为了更好地应对施工过程中存在的质量问题,通过收集沥青路面下面层施工数据,建立多元线性回归模型,分析各筛孔通过率与空隙率和渗水系数的影响关系,据此指导当空隙率或渗水系数出现大幅度波动时进行施工配合比的优化调整。总结广东省多个高速公路项目沥青路面下面层的施工经验,提出下面层GAC-25各筛孔通过率合适的控制范围。In order to better cope with the quality problems existing in the construction process,by collecting the construction data of the lower layer of the asphalt pavement,a multiple linear regression model has been established to analyze the relationship between the passage rate of each sieve and the porosity and water permeability coefficient.With the porosity ratio being guided accordingly,optimization and adjustment of the construction mix ratio have been conducted when the seepage coefficient fluctuates greatly.With Summarizing the construction experience of the lower layer of asphalt pavement in a number of expressway projects in Guangdong Province,a suitable control range for the passage rate of each sieve of the lower layer GAC-25 has been proposed.
