The invention discloses a freeze-thaw and water-resistant cold patch asphalt mixture and a preparation method thereof, and relates to the technical field of asphalt materials. When the present invention prepares freeze-thaw and water-resistant cold-patch asphalt mixture, epoxy resin core polyester fibers and maleic anhydride core polyester fibers are mixed with thionyl chloride, aminopropyl trimethoxy Silane reaction is used to prepare modified mixed polyester fiber, the modified mixed polyester fiber is mixed with ethanol to obtain a fiber solution, and asphalt, asphalt additives, diesel oil, fiber solution and limestone mineral materials are mixed to obtain freeze-thaw and water-resistant cold Make up asphalt mixture. The freeze-thaw and water-corrosion resistant cold patch asphalt mixture prepared by the invention has excellent waterproof performance and frost resistance performance. |
