Laboratory Investigation of the High Temperature Rheological Property of Activated Coal Gangue Modified Asphalt Binder

Abstract:

The coal gangue is one of the largest industrial solid waste emissions in our country at present, the research about making coal gangue as the filler to modify the properties of asphalt is still blank both at home and abroad. Using rotational viscosity test and dynamic shear rheological test (DSR) to study the high temperature rheological properties of the activated coal gangue modified asphalt binder when under the condition of different filler-bitumen ratio, and compared with mineral powder modified asphalt binder; Based on this, explores the mechanism of coal gangue modified asphalt binder. The results show that the activated coal gangue instead of mineral powder can make the high temperature performance of asphalt binder increases sharply. Research results provide feasible basis of activated coal gangue mineral powder can instead of mineral powder improving the high temperature rheological performance of asphalt binder.
