Abstract
This paper presents the results of pressure settlement behavior of strip footing resting on poorly graded sand reinforced with tire strips in layers to improve the bearing capacity. The tire strips of length 3B, 4B and 5B (B = width of footing) and 70 mm width were used. The tire strips were placed at 0.4B, 0.6B, and 0.8B from the base of the footing. The tests were carried at 14, 14.2, and 14.3 kN/m3 dry unit weight of sand. From this investigation, it was observed that the bearing capacity of reinforced soil increases with the increase in length of reinforcement, depth of reinforcement, and dry unit weight of sand. With increase in the depth of reinforcement layer, length of reinforcement and number of layer significant reduction in the settlement of sand was observed. It was observed that the settlement reduction effect was higher at higher unit weights.
