摘要
为了探讨大粒径透水性沥青混合料(LSPM)沥青用量与水稳定性的关系,对不同沥青用量的试件进行了常规浸水马歇尔试验、真空饱水马歇尔试验及冻融劈裂试验。试验结果表明,在理论上存在着一个最佳的沥青用量使得LSPM的水稳定性最好;其抗水损能力主要依靠沥青膜厚度来保证,在满足沥青析漏质量损失前提下,应尽量选择较大的沥青膜厚度。
In order to study the relationship between large stone porous asphalt mixtures（ LSPM ） amount＆amp;nbsp;and water stability,the author operates the immersion Marshall test,vacuum water - saturated Marshall test and freeze - thaw splitting test with different asphalt amounts. The test results show that there is an optimum asphalt amount that makes the water stability of LSPM best. Its ability to resist water damage mainly relies on the asphalt film thickness. Under the premise that meet the quality of asphalt analysis leakage loss,people should try to choose the larger asphalt film thickness.
