摘要
文章采用马歇尔试验方法,在不同温度下成型试件,测试马歇尔体积参数的变化,分析温度对SMA沥青混合料毛体积密度和空隙率的影响,并根据机场沥青道面修补材料空隙率3%～5%的要求,探讨机场沥青道面修补材料的合理压实温度。
The article used Marshall test methods to mold the specimens at different temperatures, tested the change of Marshall volume parameters, and analyzed the impact of temperature on the bulk density and porosity rate of SMA asphalt mixture, and according to the the porosity requirements of 3%-5% for airport asphalt pavement patching materials,i t discussed the reasonable compaction temperature of airport asphalt pavement patching materials.
