摘要
文中将微波加热方法替代传统热辐射,研究微波作用下不同旧料(铣刨料)掺量下再生沥青混合料性能的变化规律,提高路用性能。微波加热具有加热速度快、操作成本低、操作方便等优点。本研究采用AC-13型级配为研究对象,选择合适的集料、矿粉等进行配合比设计,采用马歇尔设计法,得出掺加不同比例的RAP及掺加炭黑或钢棉纤维的再生沥青混合料的矿料级配组成和最佳油石比。
Nowadays,the heat recycling technology of asphalt mixture recycling(RAP)is receiving extensive attention.Applying microwave heating method to RAP thermal regeneration has the advantages of high heating speed,low operation cost,convenient operation,etc.In this study,AC-13 gradation is used as the research object,and appropriate aggregate and mineral powder are selected for mix proportion design.This study intends to adopt steel cotton fiber and carbon black as wave-absorbing fillers,and adopt Marshall design method to obtain mineral aggregate gradation composition and optimum oil-stone ratio of recycled asphalt mixture mixed with different proportions of RAP and carbon black or steel cotton fiber.
