Problems solved by technology

[0004] The disadvantage of these patents is that the colored asphalt binder needs to be heated in an iron container during use, and after heating, it must be poured into the mixing equipment through an iron pipeline, and it must be heated in an iron container before entering the mixing tank. Metering, all these processes are to avoid the pollution of black asphalt, and none of the above devices can use black asphalt, the mixing equipment needs to be specially modified, and special vehicles for transporting liquid asphalt are required during transportation, or additional De-barrel equipment and colored asphalt storage equipment need to install special dyeable binder conveying pipes and special dyeable binder measuring scales when used on mixing equipment. Compared with black asphalt, there is a big difference in performance; in addition, because the mixture prepared by this asphalt generally needs to be paved at least 3 cm thick, the cost per square meter of colored pavement is very high
The problem in the above patents is that the prepared emulsified asphalt either has a low softening point or has the disadvantage of storage segregation

Abstract

The invention discloses a color emulsified asphalt and preparation method thereof, characterized in that color bituminous cements, emulsifier, water and modifying SBR rubber latex are included. According to proportioning by weight, parts of components are: 50.0 to 75.0 of color bituminous cements, 0.5 to 3.0 of emulsifier, 1.0 to 10.0 of modifying SBR rubber latex; 20 to 40 of water. The component and weight percent of the color bituminous cements comprise 30% to 65% of petropols, 1% to 3% of N,N'ethylidene bioleoylamido; lubricant or extract oil residual of lubricant. By selection of bituminous cements, in particular small amount of N,N'ethylidene bioleoylamido and SBR rubber latex, compared with other bituminous cements formulation, the formulation has better adhesiveness, which can prevent damages such as water damage, loose and peeling off of color path surface paved as well as tracks.

Description

technical field [0001] The invention belongs to road engineering emulsified asphalt and its processing technology, and specifically introduces a compound modified color emulsified asphalt formula for color micro-surfacing and a preparation method thereof. Background technique [0002] Colored asphalt pavement has been widely used in highways, bicycle lanes, sidewalks, bus lanes, pedestrian areas, squares and home driveways. [0003] At present, there are many patents and documents disclosing their respective colored asphalt binders, some of which have been industrialized, such as the technologies disclosed in US4629754, US5340869, GB1226234, EP-A0179510, and EP-A0330281. Chinese patent ZL03802619.X discloses a colorable binder composition for synthesizing asphalt, which contains resin, lubricating oil and / or lubricating oil extract and represented by the following general formula and based on the entire composition Amide additives whose content ranges from 0.05 to less than...
