Problems solved by technology

Moreover, the epoxy asphalt aggregate that has been mixed must be transported from the mixing station to the construction site under the condition of heat preservation. Transportation is difficult. On the other hand, during the heating process of epoxy asphalt, asphalt fumes harmful to human body will be produced, which will have a great impact on the body of the constructor and the environment.

Abstract

The invention provides a cold-mix epoxy asphalt repair material and a preparation method thereof. A cold-mix type epoxy asphalt repair material includes part A and part B; in parts by weight, the part A includes the following components: 100 parts of asphalt; 5 parts to 50 parts of asphalt thinner; 10 parts to 50 parts epoxy asphalt compatibilizer; 5 to 50 parts of epoxy resin curing agent; in parts by weight, the B part includes the following components: 40 to 100 parts of epoxy resin; 5 to 50 parts of Epoxy diluent; the weight ratio of part A to part B is (0.5-5):1. The cold-mix epoxy asphalt repair material provided by the invention has better construction fluidity at room temperature, and is easier to penetrate into cracks on the road surface for repair; and it can be stirred and used at normal temperature without heating and heat preservation for transportation.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cold-mix epoxy asphalt repair material that can be stirred and used at normal temperature without heating and heat preservation transportation and a preparation method thereof. Background technique [0002] Epoxy asphalt is developed on the basis of ordinary asphalt. It has excellent high temperature stability, low temperature crack resistance, super fatigue resistance and excellent durability. The Marshall stability of the mixture obtained with stone can be More than 40KN, while the stability of ordinary asphalt concrete is only 8KN ~ 12KN, the difference is 4 to 5 times; the splitting strength can reach 4MPa, which is much higher than ordinary asphalt mixture, and the fatigue life is almost 10 times that of ordinary asphalt concrete ~ 30 times. Based on the excellent performance of epoxy asphalt, it is widely used in steel bridge deck pavement, tunnel pavement pav...
