摘    要:以SUP16型沥青混合料为例,对现场施工中不同离析状况的沥青混合料进行了性能分析和试验研究,分析了沥青混合料集料离析和温度离析与空隙率的变化关系,以及空隙率对沥青路面压实度和平整度的影响.结果表明:粗集料集中混合料的空隙率平均值为9.5,吸水率高达2.0,粗集料离析对沥青混合料性能的影响更严重;空隙率的变化受沥青混合料温度的影响很明显.随着温度降低幅度增加.空隙率与设计值的偏离增大.路面的压实质量和平整度变差.

关 键 词:沥青混合料  集料离析  温度离析  空隙率  压实度

Abstract:Based on the SUP16 asphalt mixture,some experiments is made to study the performance of segregation asphalt mixture.An analysis is made of the influence of the gradation segregation and temperature segregation on the porosity of asphalt mixture,and the compaction degree and the evenness of pavement.The results shows that the coarse aggregate segregation has a greater influence than fine aggregate segregation on the performance of asphalt mixture under the different levels of segregation.The average porosity...
Keywords:asphalt mixture  gradation segregation  temperature segregation  porosity  the compaction degree
