 ABSTRACT

This paper deals with drawing the pressure settlement curves of the unreinforced and waste tire-fiber reinforced soil using constitutive law of soil. The plate load tests and triaxial tests were performed on waste tire-fiber reinforced sand at relative densities of 70%, 80% and 90% with different fiber contents of 0%, 0.25%, 0.50%, 0.75% and 1.0%. Angle of internal friction and hyperbolic constant (a) were found from triaxial tests at all the fiber contents and relative densities. It has been observed that the predicted values of settlement match reasonably well up to approximately two-third of the ultimate bearing pressure.

Keywords: Angle of internal friction, Constitutive Laws, Triaxial Tests, Pressure Settlement Curves.
