Experimental Research on the Performances of Warm Mix Recycled Asphalt Mixture in Road Application
The effect of sasobit’s quantity exerted on the asphalt viscosity was researched firstly in this paper, and the mixing temperature of warm mix recycled Asphalt mixture was determined. Then, the technical performances of warm mix recycled asphalt mixture on high temperature, low temperature and water stability were studied through systematic experiments. And compared the technical indexes with that of hot mix asphalt. The results showed that sasobit could reduce asphalt viscosity significantly, so it could lower the mixing and compaction temperatures of the recycled asphalt mixture. The technical indexes of warm mix recycled asphalt mixture conform to the current specifications, so it can be used in many pavement structures.
