Abstract:

To determine the optimal ratio of reactive elastomer terpolymer（RET） and rubber modified asphalt， the quantitative relationship between asphalt performance and the content of RET， rubber and oil was comprehensively investigated based on Design-Expert. The modification mechanism of composite modified asphalt was investigated by Dynamic Shear Rheometer， Infrared Spectrometer and fluorescence microscope and the road performance and fatigue performance of composite modified asphalt were verified and evaluated. The results show that the relationship between asphalt performance and the content of RET and rubber is not linearly， the optimum content of RET， rubber powder and oil is respectively 1.69%， 16.52% and 1.83% of the asphalt. The RET/rubber powder composite system can react with asphalt to generate new absorption peaks， which weakens the boundary between the modifier and asphalt. Thus， the compatibility of rubber powder and asphalt and the low temperature performance of RET modified asphalt were improved， which can significantly improve the road performance of asphalt mixture.

Key words: road engineering, modified asphalt, reactive elastomeric terpolymer, rubber powder, component optimization, modified mechanism
