Abstract:
The law of the viscosity and four-component of the asphalt rubber was researched with the time of the production and storage. Some test methods such as the infrared absorption spectrum analysis, fluorescence microscopy and differential scanning calorie were adapted to analyze ground tire rubber modified asphalt mechanism. Study results indicate that asphaltenes, saturated copies, aromatic copies decreased, viscosity increased with the crumb rubber powder adding into the asphalt. The crumb rubber powder can absorb the oil of the asphalt; also, it dissolves, depolymerizes and degenerates under hot temperature conditions. The active material which has been added in the ground rubber power can enter into the colloid system of asphalt to improve the temperature susceptibility and anti-aged performance of asphalt. Under normal temperature and low temperature condition, the undissolved ground tire rubber powder pellets in the modified asphalt. Such pellets would make the elastic performance and resistibility to cracking of the modified asphalt better. 2 tabs, 7 figs, 10 refs.
