Abstract

The invention discloses a high and low temperature resistant asphalt added with cetyl alcohol modifier and a processing method thereof. The high and low temperature resistant asphalt is made of base asphalt, styrene-butadiene rubber, powdered sulfur chloride, montmorillonite, linolenic acid, glycerin aqueous solution, and cetyl alcohol. First, the base asphalt is heated, and then linolenic acid and powdered chlorine are added. Sulfur, styrene-butadiene rubber, montmorillonite, and asphalt are modified, and then through a high-speed grinding process, after the dispersion is uniform, glycerin aqueous solution and cetyl alcohol modifier are added to further modify its stability. Finally, the product can be obtained after cooling down and developing in the later stage. The prepared modified asphalt product is not prone to delamination, and the processing flow is short, so it has a good application prospect.

Description

technical field [0001] The invention relates to a road asphalt, in particular to a high and low temperature resistant asphalt added with a modifier and a preparation method thereof, belonging to the field of asphalt processing. Background technique [0002] In recent years, bituminous compositions have been widely used in road paving. As the requirements for road surfaces are increasing, asphalt roads with excellent strength, flow resistance, and wear resistance are required. Therefore, it is necessary to prepare asphalt roads with higher softening points, Asphalt compositions with high mechanical strength such as elastic modulus need to be improved with various copolymer modifiers. [0003] Some modifiers added have poor compatibility with asphalt, resulting in reduced performance of asphalt and affecting the use effect. In terms of patents: CN201010522786.5 is a wide-area modified asphalt preparation technology, using powdered styrene-butadiene rubber as the first modifie...
