Abstract

A high-performance anti-rutting modified asphalt, which is made of the following raw materials in parts by weight: 16-27 parts of asphalt, 0.2-0.4 parts of defoamer, 0.2-0.6 parts of cationic emulsified asphalt powder, and 7-9 parts of rubber powder 1-4 parts of glycidyl methacrylate, 0.6-1.5 parts of dioctyl sulfosuccinate sodium, 0.4-1.5 parts of azobisisobutyronitrile, 3-7 parts of guar gum, 4 parts of zirconium dioxide ‑5 parts, 12‑18 parts of atactic polypropylene, 1‑2 parts of magnesium alkyl ether sulfonate, 1.5‑3.6 parts of phenyl salicylate, 4‑7 parts of stearic acid, 3‑5 parts of diatomaceous earth, Silicon carbide whiskers 4‑7 parts, talcum powder 12‑16 parts. The beneficial effects of the present invention are: the high-performance anti-rutting modified asphalt of the present invention can prevent the formation of ruts and torsion damage, increase the high-temperature shear resistance of asphalt, greatly improve the anti-skid property and wear resistance of the road surface, and have simple process and low cost Low.

Description

technical field [0001] The invention relates to a high-performance anti-rutting modified asphalt. Background technique [0002] Rutting on asphalt pavement is the main damage phenomenon of highway. At present, due to its good continuity, stable and comfortable driving, good shock resistance, and convenient maintenance, asphalt pavement has been widely used in high-grade highways in our country. However, with the development of the economy and the increasing traffic volume of modern highways, problems such as increased axle load, large-scale vehicles, serious overloading, and channelization of vehicles have become increasingly prominent, causing many asphalt pavements to be damaged shortly after they are put into operation, such as Cracking, oiling, peeling, rutting, etc. According to many road surveys, among the many diseases of asphalt pavement, rutting has always been one of the main problems of asphalt pavement damage. Changes in the use environment pose a severe chall...
