微波敏感型沥青再生剂在坑槽修补中的应用
|
摘要
为解决目前沥青路面坑槽修补中存在的问题,对利用微波敏感型沥青再生剂结合LWX-300Ⅱ型沥青混合料微波加热车再生的沥青混合料路用性能、温度变化特性等进行了研究,并对其作用机理进行了分析.结果表明,微波敏感型沥青再生剂改变了微波能量在混合料中的分布规律,使再生混合料升温降温速率均快于未添加该再生剂的混合料,有利于坑槽修补施工;微波敏感型沥青再生剂再生的沥青混合料高温、低温,以及水稳定性均得到了提升,且经济效益显著.
In order to solve the current problems existing in pothole repair of asphalt pavement,performances and temperature variation characteristics of the recycled asphalt mixture by microwave sensitive asphalt rejuvenate agent combined with LWX-300 II asphalt mixture microwave heating vehicle were studied,and the mechanism of action was also analyzed.The results show that the microwave sensitive asphalt regenerant changes the distribution rule of microwave energy in the mixture,making the temperature rise and fall rate of the regenerated mixture faster than that of the mixture without the regenerant,which is beneficial to pothole repair construction.The high temperature,low temperature and water stability of the asphalt mixture regenerated by the microwave sensitive asphalt regenerant are improved,and the economic benefit is remarkable.
