摘　　要：通过对沥青混合料(AC-25C)粗型级配试验段二种级配与二种碾压方式的不同组合,确定了三种方案进行下面层试验段施工,经三种方案试验段施工室内成型试件进行马氏等试验,结合试验段现场不同位置取样进行级配对比分析和现场密实度、渗水检测结果比较分析,确定较优的级配和碾压方式,经试验段再次验证比较,所选定施工方案对沥青路面AC-25C粗级配低温条件下规模施工的质量控制提供了参考依据。Through the different combination of two grading and two rolling methods in the coarse grading test section of asphalt mixture(AC-25C),three schemes are determined to carry out the construction of the lower layer test section.Through the comparison and analysis of the test results in the construction room and in the field of the three schemes test section,the better grading and rolling methods are determined.
