Repeated Loading Triaxial Test on Bentonite-Slag-Tire Mixture

Abstract

A road may be built on expansive soil. Therefore, it is important to know the behavior of soil in the presence of other additives such as slag and tire; which in these days research wants to use them in geotechnical and pavement projects. One of the potential way to investigate the issue is application of by-products. Among all by-product/waste, slag and tire were selected in this study. This study investigates the effect of tire and slag into the behavior of bentonite under repeated triaxial loading. For the purpose of this research, RLTT was employed. The RLTT device represents real pavement condition in laboratory scale. Three percentage of slag along with three percentage of tire were employed. The results proved that a sample with up to 15% tire behaves better against permanent deformation which the effect of slag was limited against permanent deformation.
