Colored asphalt cementing material suitable for heavy traffic and preparation method thereof

Abstract

The invention relates to a colored asphalt cementing material suitable for heavy traffic and a preparation method thereof. The colored asphalt cementing material is prepared from rubber oil, petroleum resin, SBS (Styrene Butadiene Styrene) and a modifier, wherein by metering according to 100 percent of the content sum of the rubber oil, the petroleum resin and the SBS in percentage by weight, the content of the rubber oil is 37 to 50 weight percent, the content of the petroleum resin is 35 to 55 weight percent, the content of the SBS is 8 to 12 weight percent, the modifier accounts for 2 to 3.5 weight percent of the sum of the rubber oil, the petroleum resin and the SBS, and the modifier is prepared from SBR (Styrene Butadiene Rubber), polyolefin type plastic, polyester type plastic and a coupling agent. The colored asphalt cementing material disclosed by the invention and a mixed material can be used for pavement of a heavy traffic road, and the colored asphalt cementing material is simple in formula and convenient in preparation.

Description

technical field [0001] The invention belongs to the technical field of materials used in road engineering, and in particular relates to a colored asphalt binder suitable for heavy traffic and a preparation method thereof. Background technique [0002] Colored asphalt pavement refers to mixing colored asphalt binders, aggregates, pigments and additives at a specific temperature, and then paving and rolling to form a pavement with certain strength and use function. Colored asphalt binder is the main component of colored asphalt, which is generally light-colored or colorless, and is made by blending aromatic oils, polymers, resins and other additives. [0003] The light-colored asphalt synthesized from petroleum resin and lubricating oil does not have asphaltene and other macromolecular substances in traditional asphalt, so the performance of colored asphalt is still far behind that of ordinary petroleum asphalt, especially the high-temperature performance, and the aging resist...

AI Technical Summary

Problems solved by technology

However, the above-mentioned modified colored asphalt binders are all prepared by adding raw materials and additives together, the preparation process is complicated, and the reaction is not complete enough.

CN 105295402A discloses an auxiliary material for enhancing the high temperature stability and aging resistance of colored asphalt binder, which is prepared by mixing nano-titanium dioxide with a coupling agent, but the high temperature resistance and aging resistance of the colored asphalt binder using this auxiliary material Still not particularly ideal, cannot be used for heavy-traffic high-grade roads on motorways
