Abstract

The invention relates to the technical field of preparation of asphalt, in particular to chlorine substituent modified color water-permeable asphalt which has relatively good adhesive property. The chlorine substituent modified color water-permeable asphalt is prepared from the following components in parts by weight: 100 parts of mineral aggregate, 60 to 80 parts of colored stone, 50 to 80 partsof asphalt, 70 to 90 parts of petroleum resin, 3 to 10 parts of coupling agent, 1 to 3 parts of cross-linking agent, and 0.05 to 2 parts of chlorine substituent modifier. By virtue of the technical scheme provided by the invention, chlorine atoms are introduced onto a polymer molecular chain of asphalt by virtue of the chlorine substituent modifier, so that the polarity of the polymer is improved,the compatibility of the asphalt with other substances is improved, the free energy of the surface of the asphalt is changed by virtue of a chemical combination way, and the adhesive strength betweenthe asphalt and other interfaces can be improved.

Description

technical field [0001] The invention relates to the technical field of asphalt preparation, in particular to a chlorine substituent-modified color permeable asphalt and a preparation method thereof. Background technique [0002] With the development of society, permeable pavement materials are becoming more and more common in our daily life. At present, the two most commonly used permeable pavement materials are: permeable cement concrete and permeable asphalt concrete. Permeable cement concrete has the characteristics of easy access to raw materials, no rutting, and good durability. However, due to its own material characteristics, it is easy to break and block, resulting in poor water permeability. Therefore, more and more people are beginning to carry out research on permeable asphalt concrete. [0003] The Chinese invention patent with the publication number CN105906233A discloses a high-performance colored permeable asphalt concrete and its preparation method. It is m...
