Abstract

To solve the problems of slow strength formation, poor water stability, and durability of solvent-based cold curing material, the water-cured polyurethane material was selected to prepare cold curing material, and its road performance was studied through laboratory tests, and compared with Japanese reactive cold patch mixture and solvent-based cold patch mixture. The results show that the forming strength, dynamic stability, residual stability ratio, and splitting strength ratio of the cold patch mixture prepared by water-cured polyurethane are better than that of the cold patch mixture prepared by water-cured polyurethane-modified asphalt. The maximum damage strain of cold complement prepared with water-cured polyurethane-modified asphalt is better than that of cold patch mixture prepared with water-cured polyurethane. AC-type water-solidified cold patch mixture has excellent road performance and is suitable for rapid repair of sections. It is suggested that AC gradation should be used for a water-cured cold patch mixture. The research results provide technical support for the popularization and application of a water-solidified cold patch mixture.
