Ismail Civil Engineer, Public Works Department of Malaysia ABSTRACT Stabilisation of the subgrade layer is an alternative method to reduce the thickness of the pavement layer, thus reducing the cost of road construction. This paper details a study on the cement stabilisation method of pavement soil subgrade for low volume roads. The study area is located at a housing scheme known as Rimbunan Kasih in Dungun, Malaysia. The scope of this study involved mix design in the laboratory and site verification. The laboratory tests involved soil classification, compaction test, unconfined compressive strength and California Bearing Ratio (CBR) tests while site verification tests comprised of field density test and unconfined compressive strength tests. From the laboratory tests, it was determined that the type of soil for the study area (silty clay) was suitable to be stabilised using cement based on the results obtained from soil classification test and unconfined compressive strength achieved of more than 0.8MPa obtained after the addition of 5% cement by weight. Field density test achieved more than 95% laboratory compaction density and unconfined compressive strength of 1.01 MPa, indicating that the method was successfully implemented as site. It is recommended that future research should be carried out on more sites and on different types of soil to determine the suitability of cement as additive for subgrade stabilisation.
