Environmental protection inorganic powder material and polymer composite modified emulsification asphalt grouting material

Abstract

The present invention is emulsified asphalt grouting material modified with inorganic powder and polymer. The modified emulsified asphalt grouting material may be filling and reinforcing grouting material comprising emulsified asphalt in 25-35 weight portions, inorganic powder in 65-75 weight portions and protecting agent in 10-20 weight portions; or waterproof grouting material comprising emulsified asphalt in 65-75 weight portions, inorganic powder in 25-35 weight portions and protecting agent in 10-30 weight portions. The modified emulsified asphalt grouting material has high grouting performance, high transmission capacity, no demulsification during pressure grouting, high binding with interface, high curing speed, excellent waterproof effect and other advantages. It may be applied for highway maintenance, foundation stabilization and waterproof engineering.

Description

technical field [0001] The invention relates to a material mainly used in highway and construction industry, especially in the repair and maintenance of expressway, as well as waterproof and reinforcement engineering in construction industry. Background technique [0002] With the rapid increase of traffic flow and the continuous increase of the tonnage of heavy-duty vehicles, the wear and tear on the road surface and the damage to the base layer of the road surface are greatly increased than before. After the joint filling material failed, the rainwater continued to infiltrate into the base layer. Under the influence of its own weight and the gravity of the vehicle, there was a serious gap between the base layer and the concrete plate in some sections of the road, resulting in cracks, cracks, cracks, and cracks in the road surface plate. Breakage, breakage, damage, etc. In addition, the erosion and hollowing of rain (snow) water can easily cause cracks on the road surface;...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is, in order to overcome the performance deficiency that exists in the grouting material (cement+fly ash+water glass etc.) that is used for reinforcing and waterproofing treatment to existing road at present, adopt traditional grouting material to road Due to the poor overall effect and short duration after the reinforcement treatment, repeated repairs and maintenance are often required. An environmentally friendly inorganic powder material and polymer composite modified emulsified asphalt grouting material, including filling and strengthening grouting material, is proposed. And waterproof grouting material, which does not break the emulsion during pressure grouting and has good groutability during construction; the grouting material can not only meet the base reinforcement and surface waterproofing of rigid pavement (cement pavement) by changing the proportion, but also It can meet the requirements of base reinforcement and surface waterproofing of asphalt pavement, and has comprehensive properties such as excellent wear resistance, strength, aging resistance, excellent waterproof effect and good permeability.
