Problems solved by technology

However, epoxy-modified asphalt or cement repair materials have disadvantages such as complex preparation process, high temperature and precise temperature control during mixing, slow curing in the later stage, and long open traffic time, and organic materials such as epoxy resin are easy to age
[0003] In view of the above problems, Chinese patent application CN102584109A discloses an epoxy resin concrete repair material, which can achieve high strength within a few minutes by microwave curing, but does not add anti-aging agent, so the weather resistance is not ideal, and the operation It is more cumbersome and needs special heating equipment to achieve rapid curing
Chinese patent CN101497510 discloses a modified epoxy resin concrete material cured at room temperature. Two light stabilizers, carbon black and ultraviolet light absorber, are added to the formula to improve the light aging resistance of the material, but it does not affect the durability of the material. Other aging factors such as heat and water (humidity) are not considered, and the curing is still slow

Description

technical field [0001] The invention belongs to the field of road surface repair, and in particular relates to a weather-resistant and quick-drying road surface damage repair material and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, my country's road traffic construction has made remarkable achievements. The mileage of highways has reached 4.2 million kilometers, including 96,000 kilometers of expressways, ranking second in the world. Concrete pavement is mainly used in existing roads, and its quality is better and its service life is longer. However, concrete pavement is prone to cracks, potholes and other diseases during use, which affects traffic safety and comfort, and even causes serious economic losses. Therefore, any damage should be repaired in time. Traditional pavement repair materials include ordinary cement concrete or asphalt concrete, which have the disadvantages of excavating the damaged surf...
