Colored asphalt cementing material and preparation method thereof

Abstract

The invention discloses a colored asphalt cementing material and a preparation method thereof. The cementing material comprises the following raw materials in percentage by weight: 10% to 40% of C5 petroleum resin, 10% to 40% of C9 petroleum resin, 30% to 70% rubber oil, 2% to 8% of ethylene-vinyl acetate copolymer, 2% to 8% of polyamide resin, and 2% to 8% of polyurethane. The preparation method comprises the following steps: heating the rubber oil with a mass percentage mentioned in the claim 1 to a temperature of 170 DEG C, then adding C5 petroleum resin, C9 petroleum resin, ethylene-vinyl acetate copolymer, polyamide resin, and polyurethane with the weight percentages mentioned in the claim 1 into the rubber oil, and stirring for 2 to 4 hours so as to obtain the colored asphalt cementing material. The cementing material has the advantages of strong high-temperature performance, good thermal stability, strong adhesiveness, good flexibility, strong water-damage resistant performance, and simple preparation method, and is especially suitable for being applied to southern areas under the situations of high-temperature, large traffic amount, or porous pavement.

Description

technical field [0001] The invention relates to a colored asphalt binder and a preparation method thereof. Background technique [0002] The use of colored asphalt concrete to pave the road surface in the road, one of which can beautify the city, improve the road environment, and show the effect of urban style, is specifically used in urban streets, squares, scenic spots, parks and tourist landscape roads; the second color asphalt pavement has Inducing traffic flow and making traffic management intuitive, it is specifically used to distinguish road sections and lanes with different functions, so as to improve the driver's recognition effect, increase road traffic capacity and traffic safety; its three new colored asphalt pavements are more efficient than ordinary asphalt The friction coefficient of the road surface is high, so it will also have an anti-skid effect. When the driver brakes in an emergency, the colored pavement can prevent the vehicle from skidding. Under the...

AI Technical Summary

Problems solved by technology

The performance of colored asphalt mixture can be partially improved by adding a large amount of high molecular polymers such as SBS, PE, EVA, and SBR, but the effect is still unsatisfactory

If the amount of polymer added to the colored asphalt exceeds 10%, although the high-temperature performance of the colored asphalt mixture can meet the requirements, it will cause the problem of excessive viscosity, which will lead to the production, storage, transportation, pumping and mixing of the colored asphalt. There are problems in paving, rolling and other links; on the other hand, the cost of colored asphalt with high polymer content is very high

Due to the insufficient high-temperature performance of colored asphalt, it cannot be used in occasions such as high temperature in the south, large traffic volume or permeable road surfaces.
