Abstract

The invention discloses a rubber cold-mixed epoxy asphalt mixture for repairing cracks and a preparation method, which is prepared from the following raw materials in parts by weight: basalt gravel mineral material with a particle size of 0-3mm, 40-48 parts; 3 10-15 parts of basalt crushed stones with a particle size of 5-5mm; 25-37 parts of basalt crushed stones with a particle size of 5-10mm; every 100 parts of basalt crushed stones corresponds to: rubber particles, 9-11 parts ; Waterborne epoxy resin, 7-9 parts; Emulsified asphalt, 2-4 parts; Mineral powder, 0.1-0.25 parts; Accelerator, 0.5-1 part; Defoamer, 0.01-0.05 parts; Part; Described water-based epoxy resin comprises A component water-based epoxy emulsion and B component curing agent, and the ratio of the weight portion of described A component A water-based epoxy emulsion and B component curing agent is (1-2.5): 1. The fluidity of the rubber cold-mixed epoxy asphalt mixture provided by the invention obviously improves the construction fluidity of the system, the mixing can be completed at normal temperature without heating, and the construction cost is low and the pollution is small.

Description

technical field [0001] The invention belongs to the field of highway maintenance, and relates to a cold patching material for road cracks, in particular to a rubber cold-mixed epoxy asphalt mixture for crack repair and a preparation method thereof. Background technique [0002] At present, my country's highway construction has entered the stage of simultaneous construction and maintenance, and with the increasingly heavy traffic load, the substantial increase in traffic volume, and the increasingly serious trend of overloaded vehicles, the speed and degree of damage to the asphalt pavement will increase. Faster and more complicated than before, road maintenance and repair will play an increasingly important role, so strengthening the research on maintenance and repair technology of asphalt pavement and how to prolong the service life of asphalt pavement will have a good market prospect. [0003] Although the performance of the hot mix repair material is stable, the asphalt fu...
