Expensive soils are fertile and very good for agriculture, sericulture and aquaculture. Though they are good for these purposes they are not suitable for laying roads. On such soil suitable construction practices and sophisticated methods of design are to be adopted. In this experimental work the soil was first stabilized with lime in the proportion of 5% and 15%, 25%. Sieve analysis, specific gravity test. Atterberg limits, compaction test and soaked California bearing ratio (CBR) test were carried out. The optimum proportion of lime was found to be 10% from the CBR results. In the second phase of the work rice husk ash was added in the proportion of 5%, 15%, 25% in addition with lime. The optimum proportion of lime and rice husk ash was found out from the test results. The addition of lime and rice husk ash to the tested soils led to an increase of the plasticity index and contributed to an increase in the optimum moisture content and a decrease in the maximum dry density. The moisture-density curves of the stabilized soils have typical flattened from compared to the natural soils.
