Soft clay is always associated with settlement and consolidation. Stabilisation of
soft clay with lime as bearing stratum is an alternative to replacement of that
material. The compression and consolidation characteristics of the stabilised
material need to be fully understood for design purposes. This paper presents the
results of study on the consolidation characteristics in terms of compressibility,
rate of consolidation and the permeability characteristics of both unstabilised and
lime stabilised soil samples using Oedometer test. Oedometer specimens of 50
mm diameter and 20 mm height were tested with respect to age at 0,7, 14 and 28
days and effective stress at 0, 200, 400, 800 and 1600 kPa. Three soil types were
selected and studied in this project; they are Tapah Kaolin, Sungai Buloh clay and
UTM clay. From the test results, it is discovered that lime stabilisation improved
the consolidation characteristics and reduced the settlement of unstabilised clay
with age especially after stabilisation phase is achieved, i.e., after the age of 14
days.
