Abstract

The invention relates to a repairing material, in particular to a repairing material for an extremely cold pavement as well as a preparation method and application of the repairing material. The preparation method comprises the following steps: step I, premixing materials with pungent smell in raw materials of the repairing material in a sealed environment to obtain a premixed raw material; step II, performing hot melting stirring on a resin material while the step I is performed to obtain a hot melting raw material; step III, mixing Portland cement with delayed coagulation sodium salt, fine sand and the hot melting raw material to obtain a primary raw material; and step IV, aggregating and mixing the premixed raw material and the primary raw material in a closed environment. The emissionof the pungent smell is blocked, and volatilization of volatile raw materials is avoided.

Description
