The Influence of Recycling Agents on the Performance of Regenerated Asphalt

Abstract:

In this paper, the ageing degree of recovered asphalt collected from old asphalt mixture is firstly estimated by comparing with virgin asphalt. Then, two kinds of different recycling agents are selected to mix with recovered asphalt. The influence of recycling agent type and content on regenerated asphalt performance is then studied. The results show serious condition of ageing and high viscosity of waste asphalt. As the recycling agent content increasing, the asphaltene and resin content of regenerated asphalt reduced, the aromatics content increased, while the saturate content showed a small increasing. Within this experiment, the penetration and the ductility of regenerated asphalt increased, while the softening point reduced as the recycling agent content increasing.
