The quality of the subgrade is depending on the geotechnical properties, strength and the stabilization technique adopted for problematic soil in order to increase the bearing value. In Malaysia, soft soil is a challenging due to very low strength value and low California Bearing Ratio (CBR) value as well. The soil stabilization process is conducted to increase bearing capacity of marine soil. An experimental works cover from identification of basic soil properties by index test, compaction test and CBR test. Though, the marine soils have to be treated and stabilized with available methods like using natural materials or additive agents. In this study, geotechnical characteristics of marine soil stabilized with CSP content were determined. The unsoaked treated marine soil stabilized with CSP was investigated. Four different compounds of the soil with 2.5, 5, 7.5 and 10% of CSP were mixed and added to determine the unsoaked CBR of the stabilized soil compounds. The results show the inclusion of CSP reduced the plasticity of the soil and highest dry density was decreased with an increase in the optimum water content. Moreover, by increasing the content of CSP the highest CBR value at 2.5 and 5.0 mm penetrations were achieved. The increasing percentage volume of water usage indicates the decreasing value of CBR. The results indicated that CSP contents have potential as a natural stabilizer for applications such as road sub-base material in road construction. The road sub-base will gain great strength with addition of CSP on marine soil.
