High-temperature properties of composite modified light-colored synthetic asphalt binders

To analyze the impact of polymer modifiers on high-temperature viscosity and rheological properties light-colored synthetic asphalt binders. Aromatic oils, petroleum resins, were selected to prepare a modified binder by physical mixing. In this study, SBS plus EVA was used modify binders, seven sets samples prepared. The binder's basic engineering measured through three major index tests; rotational test DSR measure its properties, content different analyzed influence properties. results show that compound modification method can increase is better than in improving EVA's low has little effect Too much will improve viscosity. Modification compounds may also rutting resistance degrade RTFOT aging process be impaired. should not exceed 6%.
