1results about How to "Lower mixing temperature" patented technology

The application discloses a warm-mixing in-place hot recycling asphalt mixture modifier and a preparation method thereof. The modifier comprises: 90# base asphalt, coumarone-indene resin, waste rubber powder, linear 30 / 70 type SBS, 4,4'-dithiodimorpholine, butyl propionate, poly-alpha-olefin, N-(2-hydroxyethyl)dodecylamide, cocamide propyl betaine and composite release agent. The modifier can reduce the use amount of new asphalt and recycling agent to a certain extent, significantly improve the performance of the recycled pavement and solve the problems of poor low-temperature performance and poor water damage resistance of the recycled pavement. In addition, some additives contained in the modifier have certain surface-active warm-mixing agent characteristics, thereby reducing the mixing temperature and improving the compaction degree of the in-place hot recycling mixture.
