Influence of gravelly exclusion on compaction of lateritic soils

This paper uses a deltaic lateritic soil sample to study the combined influence of total gravel composition and gravelly exclusion on compaction parameters MDD (or maximum dry density) and OMC (or optimum moisture content) derived from standard laboratory compaction tests. In the end, MDD was found to vary polynomially with percentage of gravelly exclusion with improved or higher values as total gravel composition increases. OMC on the other hand was found to decrease continually with increasing gravelly exclusion but independent of the total gravel composition. Also, a model was presented in form of a family of curves to predict actual or field compaction parameters (which is devoid of gravelly exclusion) and their laboratory counterparts. This revised version was published online in July 2006 with corrections to the Cover Date.
