Mechanical properties of a cement stabilised coastal soil for use in road construction

Siddique A., . and Rajbongshi B., . (2001) Mechanical properties of a cement stabilised coastal soil for use in road construction. [Proceedings Paper]

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.

Abstract

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.
