Investigations on Replacement of Coarse Aggregates by Waste Tires for Road Construction

Abstract

Disposal of the waste and worn out tires has become a major issue in India in the past few years as it has very few uses, and if new tires are to be produced from waste rubber then it has to be melted and remolded. This process intern increases the pollution and releases toxic gases in the air, which are harmful to the environment as well as living creatures. Natural Coarse Aggregates are extracted from quarries and as a result these quarries will soon be depleted in few decades if the rate of their usage continues at this pace. As a result there was a need of a permanent solution to this perpetual problem. Keeping this in view the feasibility of use of waste tires as replacement for coarse aggregates for road construction has been experimentally assessed in this paper. Basic Mechanical and physical tests has been carried out .The experimental results by replacement of coarse aggregates up to 15% by waste tire have shown remarkable improvement in the physical properties of coarse aggregates.
