Abstract

The invention belongs to the technical field of soil curing agents and particularly relates to an efficient soil curing agent and a preparation method thereof. The soil curing agent comprises asphalt,adhesive resin, auxiliary resin, a reinforcing agent, a thickening agent and a water reducing agent, wherein the asphalt is medium-temperature asphalt; the molecular weight of the asphalt is 1650-1820; the softening point is 72-84 DEG C. The efficient soil curing agent is prepared by a manner of reasonably preparing the components and then heating and stirring. The preparation method is simple and efficient; the prepared soil curing agent has the advantages of wide application range and excellent curing effect.

Description

technical field [0001] The invention belongs to the technical field of soil curing agents, in particular to a high-efficiency soil curing agent and a preparation method thereof. Background technique [0002] The soil stabilizer can chemically and physically interact with the soil to produce a certain degree of bonding. After bonding, the compactness of the soil is increased, the internal bonding force is strengthened, the bearing capacity is increased, and the compressive strength is increased. It can be used for construction Roads, water conservancy dams, and ground laying in various places, etc. However, most of the existing soil stabilizers have the problem of poor curing effect, which is manifested in poor compression resistance and poor erosion resistance. Therefore, an efficient soil stabilizer is urgently needed in the market. [0003] The patent publication number is CN103224370A, and the Chinese invention patent whose publication date is 2013.07.31 discloses a liqu...
