【摘要】 硅藻精土作为一种新型沥青改性材料,掺配在沥青混合料中,可以改善沥青混合料的物理力学性能,提高路面工程质量。本文选用4种硅藻土,进行改性沥青的温度稳定性研究,并运用灰色系统关联度分析方法,找出硅藻土影响改性沥青温度稳定性的主要因素,从而确定硅藻土作为改性剂的基本品质,为硅藻土的使用做好准备工作。更多还原

【Abstract】 As a new type modified asphalt material, mixed with asphalt mixture, diatomite can improve mechanical property of asphalt mixture and enhance the quality of pavement engineering. In this paper, four different kinds of diatomite are selected to study the stability of temperature of diatomite modified asphalt and find out main factors of diatomite that influence on the stability of asphalt temperature by gray correlation analysis method. Thus basic qualities of diatomite as modifier are decided.更多还原
