摘要
集料是构成沥青混合料的主要结构,细集料起填充作用,对沥青混合料的路用性能影响很大;水泥作为一种硬化材料灌入沥青碎石使"柔"变"刚",大大提升整体材料的刚度,对路面性能同样影响很大。通过将沥青混合料中细集料成分去掉,转而向沥青混合料空隙灌入水泥浆,对比分析两者的高温稳定性、低温稳定性等来综合评价两者路用性能的优劣,为道路施工选材提供依据。
This paper removed the fine aggregate element in asphalt mixture and pumped the cement slurry into asphalt mixture voids. It also compared and analyzed the both high temperature and low temperature stability to have a comprehensive evaluation on both advantages and disadvantages of the road performance, which provided a basis for road construction materials selection.
