| 摘 要： | 通过采用传统的浸水马歇尔试验和冻融劈裂试验对纤维沥青混合料进行的水稳定性试验发现,这两种方法并不能有效的评价纤维沥青混合料的水稳定性。设计了真空饱水冻融循环飞散试验,以飞散损失和飞散损失速率两项指标综合评价纤维沥青混合料的水稳定性。试验结果表明,该试验方法和评价指标能更好的模拟路面实际情况,并能更有效可靠的评价沥青混合料的水稳定性能。

| Abstract: | Through testing moisture susceptibility of fiber asphalt mixture by Marshall immersion test and freezing-thawing cyclic indirect tensile test,the conclusion that the two methods can not evaluate moisture susceptibility of fiber asphalt mixture effectively is drawn.Vauum saturated freezeing-thawing cycle dispersion test was used to evaluate moisture susceptibility of fiber asphalt mixture comprehensively by flying shards losses and the loss rate.The test results show that this method and evaluation indicators can simulate actual conditions of the road better,and more effectively evaluate moisture susceptibility of asphalt mixture. |
