ASPHALT COMPOSITION CONTAINING ASPHALT MODIFIER ENHANCING VISCOSITY AND DRAINAGE

摘要

The present invention is 0.1 to 50 parts by weight of the asphalt modifier with the asphalt from 50 to 100 parts by weight were mixed in the asphalt composition of 4 to 8% by weight and 92-96% by weight of the aggregate flow in the asphalt mixture was mixed parts, the modified asphalt material is a radial styrene-based -butadiene-styrene impart tackiness, based on 100 parts by weight of the mixed resin 10 to 60 parts by weight of the base resin, mineral process oil, liquid resins, and liquid butadiene rubber, polybutene, polyisobutylene, in the oil, fat five days substituted by polar functional groups to provide a special asphalt mixture, characterized in a modified asphalt in office-part processing aid selected 5 to 70 wt.
