Abstract

The present invention is one kind of environment friendly composite emulsified asphalt material for grouting and repairing cracks in highway and building. The composite emulsified asphalt material consists of emulsified asphalt40-90 weight portions, powdered inorganic material 50-90 weight portions, nanometer material 5-10 weight portions, polymer emulsion 20-40 weight portions and water 30-80 weight portions mainly. The composite emulsified asphalt material has nanometer particle component with unique surface effect, small size effect and tunnel effect, polymer emulsion component resulting in high interface combining force and high antiaging performance, and inorganic material powder component resulting in high wear resistance, high strength, etc., so that it has high comprehensive performance, good crack repairing effect and low cost.

Description

technical field [0001] The invention relates to a filling and strengthening grouting material which is mainly used in highway and construction industry, especially crack repair and caulking repair of expressways and ordinary roads, and crack repair engineering in construction industry. Background technique [0002] With the rapid development of the economy and the rapid increase of road traffic, especially 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. Under the influence of vehicle gravity and climate change and other factors, there is a serious void between the pavement base and the surface asphalt mixture (or concrete slab) in some sections of the road, which leads to fracture and damage of the surface asphalt mixture (or concrete slab) , destruction etc. In addition, rainwater erosion and hollowing further accelerate the formation...
