The invention discloses a freezing-thawing-resistant and water-erosion-resistant cold patch asphalt mixture and a preparation method thereof, and relates to the technical field of asphalt materials. In the preparation of the cold patching asphalt mixture which is resistant to freezing, thawing and water erosion in the present invention, the epoxy resin core polyester fiber and the maleic anhydride core polyester fiber are first mixed, and then mixed with thionyl chloride, aminopropyltrimethoxyl group in turn. The modified mixed polyester fiber is prepared by silane reaction, and the modified mixed polyester fiber is mixed with ethanol to obtain a fiber solution. Asphalt mix. The cold patched asphalt mixture with resistance to freezing, thawing and water erosion prepared by the invention has excellent waterproof performance and anti-freezing performance. |
