摘要
对多孔沥青混合料特殊的压实效果进行试验研究,按照不同集料类型、击实次数、拌合及击实温度条件,分别成型马歇尔试件并测定空隙率,评价各因素对空隙率的影响,进而分析混合料的压实效果。
The paper does research on special compaction effect of porous asphalt concrete by means of test- ing the mixtures＇ air voids. The mixtures are shaped by different aggregate types, different compaction times, dif- ferent mixing temperatures or different compaction temperatures. The paper evaluates the influence of above fac- tors on air voids of the mixture, and analyzes the compaction effect according to the air voids testing results.
