摘要
Abstract
This study investigates the effects of three different warm mix additives on the softening point,25℃ needle penetration degree,5℃ ductility,135℃ kinematic viscosity,60℃ dynamic viscosity and thermal storage stability of high viscosity bitumen.The type and optimal dosage of warm mix additives were determined.The results show that the addition of warm mixing agent can effectively reduce the 135℃ kinematic viscosity,and improve the workability.At the same time,with the increasing amount of warm mix agent,the high temperature performance,adhesion and thermal storage stability are also improved,but the low temperature performance is decreased.After comprehensive consideration,the optimal type and dosage are determined to be LQW-0400 and 2.5％.关键词
