摘要:
沥青路面渗水性能是沥青路面水稳定性的一个重要指标，也是反映路面沥青混合料级配组成的一个间接指标，而压实度是路面结构施工最主要的控制指标。文章采用现场检测与室内试验相结合的方法，研究了渗水系数、混合料级配筛分及路面压实度三个主要指标。结果表明，混合料级配组成的严重影响路面结构压实度和路表渗水性能。
Asphalt pavement is an important index of water stability of asphalt pavement, and is an indirect indicator of asphalt mixture gradation. Degree of compaction is the most important control index of pavement structure construction. In this paper, the method of combination of field test and indoor test is used to study the three main indexes of water permeability coefficient, mixture gradation screening and degree of compaction. The results show that the gradation of the mixture has serious influence on the pavement structure degree of compaction and water permeability coefficient performance.
