Problems solved by technology

[0003] At present, the performance standard of commonly used colored asphalt materials adopts the standard of polymer modified or heavy traffic asphalt. The pavement thickness is usually 30-50mm, which is relatively thick. cost
In addition, the adhesion between asphalt and aggregates is poor, and the colored asphalt film will fall off after the traffic load or pedestrians walk for many times, the color durability is poor and the anti-skid decay is fast
In addition, commonly used hot-mix colored asphalt is light-colored asphalt or decolorized asphalt prepared based on asphalt performance requirements, which has poor water stability and short service life of the road surface, requiring regular maintenance

Abstract

The invention discloses chemically modified colored resin asphalt and a preparation method thereof. The asphalt consists of three components of A, B and C; the component A is epoxy resin; the component B consists of a curing agent, petroleum resin, a light-colored oil-based solvent, natural rubber and an active compatibilizer, wherein the mass parts of the components in the component B are as thefollows: 0.5-5 parts of the curing agent, 1-5 parts of the petroleum resin, 3-12 parts of the light-colored oil-based solvent, 0-3 parts of the natural rubber and 0-3 parts of the active compatibilizer; the component C is color pigment, wherein the mass ratio of the A component to the B component is (1:3)-(1:15), and the ratio of the total mass of the A component to the B component to the mass ofthe C component is (2:1)-(5:1). The chemically modified colored resin asphalt has the advantages of bright color, high strength, good flexibility, long service life, good color durability and the like. The component A and the component B have good storage stability and are convenient to construct and apply. The chemically modified colored resin asphalt is suitable for public garden road surfaces,square paving surfaces, special road anti-skid surface layers and the like, has excellent performance, has warning and beautifying functions, and thus has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of asphalt and its preparation method, in particular to a colored chemically modified resin asphalt and its preparation method. Background technique [0002] Asphalt is commonly used as a paving and waterproofing material and is thermoplastic in nature. This characteristic is manifested in the asphalt pavement. In the summer high temperature season, the road surface is prone to rutting under heavy loads. In the winter cold season, it is prone to "temperature shrinkage cracks". With the improvement of road grades and the large-span steel box girder The application of structural bridges is becoming more and more extensive, and the strategy of building a strong transportation country is proposed, so there is a higher demand for the strength, deformation resistance, water stability and fatigue durability of pavement materials. [0003] At present, the performance standard of commonly used colored asphalt materi...
