摘要
为了对桥面铺装GA10浇筑式沥青混合料的性能进行评价,首先确定了GA10浇筑式沥青混合料的级配,根据混合料流动度、贯入度及增量指标确定了最佳油石比,然后对胶结料的微观改性机理进行分析,最后通过动汉堡车辙实验、弯曲小梁实验、改进的浸水马歇尔试验、飞散试验以及冲击韧性试验分别对GA10浇筑式沥青混合料的高温、低温、抗水损害及疲劳性能进行评价。
In order to evaluate the performance of GA10 pouring asphalt mixture,the gradation of GA10 pouring asphalt mixture was first determined according to the fluidity,penetration degree and increment index of mixture,Then,the microstructure modification mechanism of cementitious material was analyzed. Finally,the dynamic hamburger rutting test,bending trabecular test,improved water immersed Marshall test,flying test and impact toughness test were respectively carried out on the high temperature,low temperature,anti-water damage and fatigue performance evaluation.
