Abstract
The various physical and mechanical laboratory tests were taken to the crushed stones and the gravel soil for revealing the property of reclaimed ground at Kobe Airport. On considering the high compressibility by the ground submerged and the particle breakage which occurred by reclaimed works, the maximum and minimum densities were set up. The specimens of the same relative density with in-situ condition were made and the laboratory tests were taken to them. Within the specified these samples, the larger fine contents was, the higher density became and the smaller liquefaction resistance became. The shear resistance angles of all specimen were larger than 37°.
