Abstract

Recently, due to lack of sand suppy, the cost of sand has increase. Therefore, alternative materials are needed. So, in this study the Crush Stone Compaction Pile used in America and Europe has been compared and analyzed Sand Compaction Pile used in Korea. Tests were performed at various sizes of Crush Stone and replacement ratio. Frist, it was compared and analyzed with low and high replacement ratio with the same size of crush stone. Second, it was compared and analyzed with different size of crush stone at constant replacement ratio. The result of these tests were compared with sand of the same replacement ratio. Here, the properties that were comares and analyzed are the ultimate bearing capacity and quantity of ground upheaval.
