Asphalt comprehensive aging method of heat-oxygen-water-ultraviolet
摘要
Abstract
A method to simulate natural pavement asphalt aging was presented based on ana-lyzing defects of traditional aging methods:pressure aging considering moisture factor after short-term aging of asphalt,then aging under ultraviolet.The experiment comparing the effect of improvement with traditional test,the performance of the asphalt after aging of re-cycling asphalt of different working times and two kinds of simulation were tested and ana-lyzed.It was found that improved method for asphalt aging degree is more serious than the traditional method.The results also showed that improved method can better reflect the nat-ural aging behavior of pavement asphalt than the traditional method,and has better equiva-lence and correspondence.关键词
