Paper Abstract

Issues concerning the structure ofsoil after compaction are important for achieving the stability ofthe soil structure itself. In this study, structure and density of soil containing sand or gravel after compaction are examined, keeping in mind the difference between the actual density measurements and theoretical values derived by the Walker and Holtzs method. Compaction experiments were performed for a mixture ofgravel or sand and finegrained fractions. Based on the results of these experiments, basic structures I and II were configured, which were used to present formulae for calculating mixing ratio of these structures within compacted soil. In addition, water immersion and peneiration tests were performed using specimens with different thegrained fractions ratios. These experiments verified that the structures of compacted soil containing gravel or sand and finegrained fractions were ofthe mixture ofthe basic structures I and II above, and the ratio ofthese basic structures within the soil are determined by the mixing ratio between gravel or sand and finegrained fractions, and furtheimore by the densith of each stnicture when compacted.
