Interlayer binding material for thin-layer pavement of cement pavement and preparation method of interlayer binding material

Abstract

The invention discloses an interlayer binding material for thin layer pavement of a cement pavement and a preparation method of the interlayer binding material. The interlayer binding material comprises 5-10 parts of water-borne epoxy resin, 10-20 parts of a water-borne epoxy curing agent, 70-85 parts of wheel-sticking-free emulsified asphalt, 0.1-0.5 part of a thickening agent and 0.5-1 part of a defoaming agent. During preparation, the waterborne epoxy resin, the waterborne epoxy curing agent, the non-sticking emulsified asphalt, the lauric acid and the ethylene oxide are uniformly mixed. The water-based epoxy modified emulsified asphalt is adopted as a binding material of the cement pavement, water-based epoxy resin can permeate into a cement base layer, the interlayer binding strength is improved, the composite drawing strength at 40 DEG C is larger than 0.4 MPa, a spatial three-dimensional network structure is formed in the asphalt after water-based epoxy is cured, the strength is high after film forming, blistering is not prone to occurring, and the water-based epoxy modified emulsified asphalt can be used as a binding material of the cement pavement. And wheel sticking is not generated when a construction vehicle paves the mixture.

Description

technical field [0001] The invention belongs to the field of bonding materials, in particular to an interlayer bonding material for thin-layer paving of cement pavement and a preparation method thereof. Background technique [0002] In view of the disadvantages of the current road maintenance technology, such as strong dependence on the original road surface, insufficient durability and low cost performance of materials, the existing materials have poor anti-skid ability, are not suitable for low temperature performance, and the snow melting is relatively low. Slow and other disadvantages. Small particle size asphalt mixture thin layer paving technology has good road performance and universal applicability for production and construction, especially for tunnels (including tunnel entrances and exits), bridge deck paving, airport runways, steep slopes and sharp bends, long longitudinal slopes and Asphalt pavement paving and old cement pavement overlaying and repairing in spec...
