Mbo residual soils are heterogeneous due to variable weathering of the jointed rock mass. The heterogeneity of residual soils is due to the influence of relic joints, presence of boulders and variability of the soil matrix. Laboratory investigations to ascertain problems associated with Mbo residual soils at plain and modified conditions were conducted. Residual soil parameters have significant effect on the overall performance or non-performance of pavement structures. Various stabilization measures were executed to determine contact behavior and compaction systems introduced to establish...
