In this study, the Young's modulus "Es" of sandy soil with and without surcharge around footings has been obtained. Tests have been conducted in field by using plate load test. Two steel rigid plates were used in testing. One circular plate with diameter 305 mm and one square plate with dimension 305 * 305 mm. Both plates have thickness of 32 mm. The settlement has been measured under different stress levels at the surface along the center line as well as the edge of the plates. The British Standard method was adopted to calculate "Es" assuming a uniformly loaded rigid plat on a semi-infinite elastic isotropic solid. It was found that the Young's modulus "Es" of sandy soil increases with increasing depth of footing. In addition, the Young's modulus "Es" of sandy soil using square plate in testing is less than that of circular plate. However, the Young's modulus increases significantly with increasing the soil relative density with and without surcharge around the footing.
