Abstract
The invention provides low-viscosity rubber asphalt which is prepared from the following raw materials in parts by weight: 80 to 120 parts of asphalt, 20 to 40 parts of tire rubber powder, 1 to 4 parts of asphalt modifier, 2 to 5 parts of petroleum resin, 2 to 5 parts of emulsifying agent and 4 to 8 parts of PTC-R. The content of the tire rubber powder in the low-viscosity rubber asphalt provided by the invention is improved, so that the consumption of waste tire can be increased; meanwhile, the low-viscosity rubber asphalt has better high-temperature performance and lower viscosity, so that the spreading and compaction are facilitated; the low-viscosity rubber asphalt has better construction performance.
Description
technical field [0001] The invention relates to a rubber asphalt, in particular to a low-viscosity rubber asphalt. Background technique [0002] Rubber asphalt is first processed from waste tires into rubber powder, and then combined according to a certain ratio of thickness and fineness. ), a modified asphalt cementitious material formed after fully swelling reaction with base asphalt. Rubber asphalt has the following advantages: 1. It has greater elasticity and elastic recovery ability at high temperature, which can improve the performance of road surface deformation resistance and fatigue cracking resistance; 2. It has better high and low temperature performance, which reduces the temperature of asphalt. Sensitivity; 3. It has the characteristics of high viscosity, anti-aging, and strong anti-oxidation ability; 4. High anti-skid function, reducing splashing when driving in rainy days, improving vision, reducing noise, and greatly improving road safety and comfort; 5. Con...
