排水型沥青稳定碎石的透水性研究

通过室内试验的不断调整，确定出三种级配，最后对它们的透水性能作了分析，结果表明：渗透系数是控制排水型沥青碎石材料透水性能的主要指标，同时也要通过其他指标的综合控制来达到实际应用效果。

Research on the permeability of the drainage asphalt stabilized crushed stone

Based on the continuous adjusting of laboratory test,the author confirms the three kinds of gradations,finally analyzes their permeability performance,results show that the permeability coefficient is the key index of controlling the permeability performance of the drainage asphalt stabilized crushed stone material,and it also need to comprehensive control based on other indexes,so as to reach the practical application effect.
