Abstract

A series of laboratory model tests has been carried out on a model strip footing to investigate the use of waste tire fiber as reinforcement to increase the bearing capacity of soil. Fiber content and depth of reinforcement at relative density 60% are considered to be the main parameters in this paper. The fiber aspect ratio of 12.5 (length = 25mm and width =2mm) was selected. The thickness of reinforcement was kept as 0.5B, 1B, 1.5B and 2B (B is the width of the footing) and four different fiber contents of 0.25%, 0.50%, 0.75% and 1.0% by weight were selected. It has been found that Bearing Capacity Ratio of soil is improved with addition of waste tire fibers at all fiber contents and thicknesses of reinforcement. A maximum value of 1.64 has been found at a fiber content of 0.75% and thickness of reinforcement 1.5B.
