Experimental Investigation on Fatigue Property of Asphalt Concrete Modified by Diatomite-Glass Fibers

Abstract:

Diatomite and glass fiber are used for modifying asphalt concrete in this paper. Besides, wet and dry processes are adopted to achieve the composite modified asphalt concrete. Meanwhile, experimental investigation has been done on its fatigue properties and dynamic mechanical property, it indicates that diatomite-glass fiber modified asphalt concrete has a better capacity to resist fatigue damage. Compared with matrix asphalt concrete, the modified asphalt concrete has higher fatigue life. Thus, its mechanical parameter of fatigue property changes obviously so as to provide a reference basis for the durability design of pavement materials.
