Problems solved by technology

[0005] However, the above prior art does not solve the problem that the curing agent in the prior art has low strength, large drying shrinkage, and easy cracking, and its properties are greatly affected by soil quality, and the curing effect on clay, organic soil and saline soil with high plasticity index is poor. Even the technical problem of no curing effect can not meet the comprehensive requirements of road construction

Abstract

The invention discloses a hardening agent for a road. The hardening agent is prepared from, by weight, 10-15% of cement, 1-5% of lime, 2-3% of fly ash, 2-3% of gypsum, 1-2% of coal gangue, 1-2% of zeolite, 3-15% of sulfonated oil, 1-2% of phosphate, 1-2% of caustic alkali, 1-2% of potassium permanganate, 2-4% of sodium chloride, 2-4% of sodium carbonate, 2-3% of calcium carbonate, 2-3% of silicon powder, 1-2% of asphalt, 5-10% of sodium silicate, 1-2% of polyacrylamide, 1-2% of polyacrylic acid, 1-2% of magnesium sulfate, 1-2% of calcium carbonate, 7-10% of tar, 0.1-1% of epoxy resin, 0.6-1% of aniline furfural, 0.3-1% of calcium acrylate and 0.5-2% of carboxymethyl cellulose. The invention discloses a roadbed hardening method. The hardening agent for the road is adopted for hardening.

Description

technical field [0001] The invention relates to a curing agent for roads and a base curing method, belonging to the technical field of roads and building construction. Background technique [0002] The curing agent for roads is an added substance that consolidates the scattered soil into an integral solid substance with a certain strength during the road construction process. Traditional curing technology is divided into physical curing and chemical curing. Physical solidification is a method to improve soil properties and achieve stable solidification without using any external materials, such as using corresponding equipment to compact the soil to reduce the pore volume of the soil, mixing different soil types, etc. The actual physical changes that lead to stable solidification of soil include evaporation, temperature change, adsorption, etc. For example, when the asphalt emulsion is solidified, the main physical change is evaporation and drying. , mixing various low-con...
