摘要
硅藻精土作为一种新型沥青改性材料,掺配在沥青混凝土中,可以改善沥青混合料的物理力学性能,提高路面工程质量。本文通过4种不同的硅藻土,进行硅改沥青高温性能研究,并运用灰色系统关联度分析方法,找出硅藻土化学成分影响沥青高温性能的主要因素,从而确定硅藻土作为改性剂的基本化学成分。
As a new type modified asphalt material,mixed with asphalt concrete,diatomite can improve mechanical performance and enhance the quality of pavement engineering.In this article,four different kinds of diatomite have been selected to study and high temperature performence of diatomite modified asphalt has been investigated.To find out main factors that chemincal components influence on high temperature performance of asphalt by gray correlation analysis method.Thus basic chemical components of diatomite as modifier have been identified.
