Deterioration of Strength of Lime-Stabilized Soils Subjected to the Repetition of Crush and Compaction

Y. Nabeshima, S. Tomohisa, and Y. Miura
Abstract—A huge amount of surplus soil and muddy soil was produced from the construction earth works in Japan. To reuse these soils in the construction sites, the soil improvements by mixing with cement or lime were sometime adopted. Recently, the case in which the improved soil was excavated, refilled and compacted was supposed. As the improved soil was excavated, refilled and compacted, it was necessary to evaluate the strength of the improved soil. However, the strength of stabilized soil was decreased by repetition of excavation, refill and compaction processes. In this paper, the deterioration of strength of the lime-stabilized soil subjected to the repetition of crush and compaction process was discussed. A series of unconfined compression tests were carried out to evaluate the deterioration of strength of the stabilized soil by repeating crush and compaction processes. As a result, it is found that the strength was decreased by repetition of crush and compaction processes from that without the crush and compaction process. However, the deteriorated strength of the stabilized soil which was repeatedly crushed and compacted had similar strength to that of the soil with one-time of crush and comaction process.

Index Terms—Deterioration, strength, repetition, crush, compaction.
