Description

technical field [0001] The patent of the invention belongs to the field of engineering materials, and specifically relates to an expansion type high molecular polymer grouting reinforcement material for road surface maintenance and a preparation method thereof. Background technique [0002] Among the existing road grouting reinforcement materials, cement materials or cement-based modified materials are the main ones. Since cement grouting materials need to be mixed with water, bleeding and shrinkage problems will inevitably occur, resulting in failure to fill the voids in the road structure. Cement-based materials are brittle materials, which are difficult to resist the bending and pulling deformation of the road under the load of wheels, and their reinforcement effect is not ideal. The common disadvantage of cement materials is that it takes a long time for curing, which is difficult to meet the demand for road traffic, especially expressway, which requires rapid opening o...
