Abstract

The invention relates to stable modified asphalt. The stable modified asphalt is prepared by, by weight, 4-8 parts of stearic acid, 3-4 parts of castor oil, 6-9 parts of oleic acid, 3-5 parts of hexadecanoic acid, 0.8-2.4 parts of sodium lactate, 0.6-1.2 parts of phenethyl phenol polypropylene oxide polyoxyethylene ether, 2-4 parts of nano silicon oxide, 3-6 parts of SBS segmented copolymer, 10-15 parts of rubber powder, 8-13 parts of epoxidized soybean oil, 0.7-1.8 parts of graphite powder, 0.1-0.2 part of chlorinated polyethylene, 0.2-0.5 part of coupling agent, 25-35 parts of asphalt, 1-4 parts of surfactant, 1-2 parts of antioxidant and 4-6 parts of dimethylbenzene. The stable modified asphalt is good in anti-rut capacity under high temperature, high in flexibility and elasticity, stable in performance, excellent in pavement performance and convenient to use.

Description

technical field [0001] The invention relates to a stability modified asphalt. Background technique [0002] Many changes have taken place in modern highways and roads. The traffic volume and driving frequency have increased sharply. The axle load of freight vehicles has continued to increase. Lanes and one-way driving are generally practiced. Coupled with the severe challenges of the climate, it is required to further improve the performance of the road surface to meet current usage requirements. Modified asphalt refers to the addition of rubber, resin and other high molecular polymers, finely ground rubber powder or other fillers and other external admixtures (external admixtures), and evenly mixed with asphalt, so that the properties of asphalt can be improved. asphalt mixture. The purpose of modification is to improve the road properties of asphalt: high temperature stability, low temperature crack resistance, fatigue resistance, improve the adhesion of asphalt, improve...
