—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.
