Asphalt for curing and repairing road and preparation method thereof

The invention relates to the technical field of road curing and repairing, and discloses asphalt for road curing and repairing and a preparation method thereof. The asphalt comprises the following raw materials in parts by weight: 100-120 parts of base asphalt, 20-30 parts of modified bentonite, 20-30 parts of modified rubber powder, 10-20 parts of styrene-butadiene latex, 9-10 parts of a modifier, 3-5 parts of furfural and 5-7 parts of an auxiliary agent. Preferably, the modifier is a mixture of a filling agent, an organic surface active compound, a weather-proof agent, a thermoplastic polymer and a solid polymer in a ratio of 3: 1: (2-4): 5: (7-9). According to the asphalt for curing and repairing the road and the preparation method of the asphalt, the modifier is added during production, and the modifier is a mixture composed of the filler, the organic surface active compound, the weather-proof agent, the thermoplastic polymer and the solid polymer, so that various properties of the asphalt, such as rut an
