Mechanical properties of a coastal soil stabilised with 1%, 3% and 5% cement have been evaluated. Experimental results showed that considerable increase in unconfined compressive strength (q sub micro), California Bearing Ratio (CBR), flexural strength and flexural modulus has been observed due to stabilisation. Durability test indicates that percentage loss in soil-cement decreases with the increase in cement content. It has been found that q sub (micro) (cured for 28 days) and CBR of samples with 3% and 5% cement fulfil the requirements of soil-cement road sub-base and base subjected to light traffic. Analyses using CIRCLY computer program were conducted to estimate the thickness of soil-cement base for paved and unpaved roads. It has been found that at a given CBR of subgrade and modulus of soil-cement, thickness of soil-cement base increases with increasing load repetitions and that at a particular CBR and load repetitions, thickness of soil-cement base decreases as modulus increases.
