Abstract
In this paper, the additive was adopted to activate crumb rubber powder to prepare a compound modified asphalt, and its mechanism of activating crumb rubber modified asphalt is studied. Mechanical testing was adopted to study the activation mechanism of additive to crumb rubber powder. Differential Scanning Calorimetry was used to analyze the performance improvement mechanism of the activated rubber to the modified asphalt. Physical models were then constructed to explain the mechanism. The results indicate that: The crumb rubber powder is dissolved totally by the additive which contains lots of oil and aromatics, then the crumb rubber powder release more solubilizer with the action of cutting at high speed, so that the crumb rubber powder can be compatible with the asphalt more steadily, and the performance of the compound modified asphalt is more superior.
