Abstract
This article studies the variation of asphalt performance with the dosage of warm mix agent,and analyzes the influence of warm mix agent dosage on asphalt penetration,softening point,and ductility based on experimental results.The results indicate that when the dosage of warm mix agent exceeds 5 ‰,the high-temperature performance of both types of asphalt will be significantly reduced;The high-temperature stability of KL90 asphalt has improved after aging,while the high-temperature stability of KC90 asphalt has decreased;The targeting degree of asphalt before aging increases with the increase of the dosage of warm mix agent,while the penetration degree and penetration ratio of asphalt residue after aging show a trend of first increasing and then decreasing with the increase of the dosage of warm mix agent.关键词
