Study on Application of Botanic Crumbed Rubber Asphalt in the Field of Road Building

Abstract:

It’s necessary to find some substitute for asphalt because of the rising price and the tension supply of petroleum asphalt with the gradually decreasing of fossil oil. Indoor tests on the pertableance of binding material made of crumbed rubber particles, botanic asphalt and petroleum asphalt as well as the pertableance of its premix are carried out. The results show that botanic crumbed rubber asphalt pertables as well as asphalt rubber, which means botanic crumbed rubber asphalt can be used as binding material in road asphalt concrete. The study provides a theory basis for the possibility of partially replacing petroleum asphalt with botanic asphalt. Botanic asphalt has much higher comparative advantages than petroleum asphalt in the aspects of social benefit and economic benefit, so there must be a bright prospect for botanic asphalt.
