摘要
沥青混合料是一种具有粘性、弹性、塑性的粘弹性材料。基于国内外研究进展,以粘弹性材料的力学特征为基础,对沥青路面结构性能要求进行分析。随后进行了室内试验,并对沥青混合料设计方法进行研究,得出了LSAM-25沥青混合料的配合比设计,对比了LSAM-25、Superpave25、ATB-25三种沥青混合料的路用性能,为大粒径密级配沥青混合料路用性能研究提供参考。
Asphalt mixture is a kind of stickiness, elasticity, plasticity of viscoelastic materials. Based on the research progress both at home and abroad, based on the mechanics characteristics of viscoelastic materials, analyze the structure of asphalt pavement performance requirements. Then the indoor test and study of asphalt mixture design method. Obtained LSAM -25 asphalt mixture ratio design, the LSAM -25, Superpave25, ATB - 25 three road use performance of asphalt mixture were compared. This paper provide reference for large particle size dense gradation asphah mixture research in the future.
