| 摘 要： | 沥青路面水损害主要原因之一在于沥青混合料缺乏足够的水稳定性.应用沥青路面分析仪(APA)对沥青混合料的水稳性进行试验研究,对APA浸水车辙试验结果进行了分析,提出浸水车辙稳定度1/K的评价指标,并利用此指标比较了不同混合料的水稳性能,同时分析了常规水稳试验的不足,证明APA浸水车辙试验能够用于评价沥青混合料水稳性.图3,表7,参9.

| Abstract: | One of the main reasons of asphalt pavement moisture damage is that the moisture susceptibility of asphalt mixtures is insufficiency.The moisture susceptibility researching was carried through by asphalt pavement analyzer(APA).APA water submerged rut testing simulated the pavement's condition when pavement encountered the water damage,it was a dynamic testing method.The result of water submerged rut testing were researched and analyzed in the paper.The water submerged stability(1/K) is brought forward.The ability of asphalt mixtures resisting water damage are compared,using them can distinguish the ability of asphalt mixtures resisting water damage,and distinguish the difference of unlikeness asphalt mixtures.The conventional testing methods have their deficiency,It indicates that APA water submerged rut testing can appraise the moisture susceptibility of hot asphalt mixtures.3figs.,7tabs.,9refs. |
