Experimental Study of Granular Rubber Waste Tire Reinforced Soil for Geotechnical Applications

Abstract:

Large quantities of waste tires are released to the environment in an undesirable way. The amount of this scrap is increasing every year. The potential use of this waste material in geotechnical applications can contribute to reducing the tire disposal problem and to improve strength and deformation characteristics of soils. This paper presents a laboratory study on the effect of granular rubber waste tire on the physical properties of a clayey soil. Clayey soil was mixed with 10% of granular rubber by dry weight. Grain size, Atterberg limits analyses and compaction tests using standard effort were performed on the clayey soil. Consolidated-drained triaxial tests at confining stresses of 50, 100, 200 and 400 kPa were run on soil and mixture. The results conveyed that the geotechnical characteristics are influenced by the addition of grained tire, improving the cohesion and the angle of internal friction the clayey soil-granular rubber mixture. This improvement depends on the level of confining stress. The compaction test results indicated that the dry unit weights and the optimum moisture for the mixture decreased in relation to clayey soil. Therefore, this mixture can be used as lightweight fill material due to its low specific weight, solving low bearing capacity and high settlement problems of embankments on soft compressible soils.
