An Investigation into the Mechanical and Strength Properties of Rubberized Asphalt Concrete

Abstract

In this study, the suitability of large rubber chunks from shredded tires as aggregates in cold mixes for road construction is investigated. The rubber was used as an additive to the asphalt binder. Thirty percent of rubber by weight was introduced into the binder at a higher temperature and the rubber was allowed to react with the binder. It was shown among other findings that for various particle sizes, the tensile strength and elastic modulus of rubber-modified asphalt concrete increased with increasing rubber/asphalt ratio with optimum properties shown at 0.30 rubber/asphalt ratios and that water has no significant effect on mechanical properties of rubberized asphalt concrete. In this study, an experimental investigation is carried out to ascertain the effect of tire rubber chips on the strength and mechanical properties of asphaltic concrete.
