Embodiment Construction

[0018] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0019] The formula of the micro-surface mixture: by weight, 100 parts of aggregate, 10-13 parts of modified emulsified asphalt, 0.10-0.39 parts of water-based epoxy resin, 0.15-0.59 parts of water-based epoxy curing agent, 1-3 parts of cement 7 to 9 parts with water.

[0020] A more optimal formula is: by weight, 100 parts of aggregate, 10-13 parts of modified emulsified asphalt, 0.10-0.26 parts of water-based epoxy resin, 0.15-0.39 parts of water-based epoxy curing agent, 1-3 parts of cement and water 7 to 9 servings.

[0021] The water-based epoxy resin and water-based epoxy curing agent used in this experiment have the following technical indicators

[0022] Using products with the above technical indicators, when the weight ratio of water-based epoxy resin to water-based epoxy curing agent reaches 1:1.5, the curing effect is the best and the best bonding p...

Abstract

The invention discloses a micro-surfacing mixing material with performances of high abrasion resistance and water damage resistance, comprising the following components by weight parts: 100 parts of aggregate, 10-13 parts of modified emulsified asphalt, 0.10-0.39 parts of waterborne epoxy resin, 0.15-0.59 parts of waterborne epoxy hardener, 1-3 parts of cement and 7-9 parts of water. Compared with the general micro-surfacing mixing material, the abrasion resistance of the micro-surfacing mixing material disclosed by the invention is improved by 51%, the water damage resistance capability is improved by 57%, the peel-off phenomenon at the micro-surface is greatly reduced, the anti-strip performance is obviously improved, the mass loss is reduced to 1.08% from general 2.36% after the load acts 30,000 times, and the coefficient of friction, the structure depth and the permeability coefficient of the material after actually used for 2 years are obviously better than that of the general micro-surfacing, so that the micro-surfacing mixing material disclosed by the invention is especially applied to hot and rainy regions.

Description

technical field [0001] The invention belongs to the field of road surface maintenance, and in particular relates to a micro-surfacing mixture with high wear resistance and water damage resistance. Background technique [0002] Micro-Surfacing is an economical, fast and effective preventive maintenance of pavement [0003] technology, with convenient construction, low engineering cost, fast open traffic, effective repair of ruts, significantly improved road [0004] The road performance of the road surface, prolonging the service life of the road surface, energy saving and environmental protection, and good comprehensive benefits have the characteristics of being very [0005] Broad prospects for promotion and application. This preventive maintenance technology has been applied in my country for more than ten years. It has expanded from general pre-curing overlay and rut filling to cement concrete pavement overlay, tunnel pavement and cement concrete bridge deck pavement. H...
