Study on Pavement Performance of Recycled Asphalt Mixture Mixed with Steel Slag
In order to explore the road performance of steel slag recycled asphalt mixture,ensure the maintenance quality of highway asphalt pavement and extend the service life of road,this paper uses steel slag as a coarse aggregate to prepare asphalt mixture,and comprehensively evaluates the road performance of steel slag asphalt mixture under different recycled asphalt content through experiments.The results show that compared with conventional SMA-13,the steel slag regeneration SMA-13 has better high temperature performance,its dynamic stability in-creases by 24.0%～32.0%,and rut depth decreases by0.02～0.04 mm.And the higher the amount of recycled asphalt,the better the high temperature stability of the mixture,the lower the low temperature and water stability,and the anti-skid performance is basically unchanged.
