The MC is often weak and lacks stability in heavy loads. This research is concerned with the potential of BA (Bottom ash) and QD (Quarry dust) as soil stabilizers based on resistance enhancement. Soil stabilization points to make strides the geotechnical features of the MC. The engineering properties of MC have been built-up, such as grain size distribution, particle density and soil plasticity. The soil sample was blended and compacted with various quantities of the BA and QD i.e. 2.5%, 5%, 7.5%, 10% 12.5% and 15% for compaction and strength test. The dry-weight method was utilized to prepare the samples. A standard Proctor test was run to determine the stabilized floor OMC and MDD. In the interim, the CBR was conducted to obtain the strength of the stabilized soil. Test results indicate that the MDD of the MC has been improved by 0.19 (g/cc) on addition of 10% BA and it has been improved by 0.246 (g/cc) when 10% QD is added when compared with untreated MC. Laboratory analyses of the cyclic plate load test revealed the ultimate load carrying capacity of the treated MC model flexible pavement has been increased by 349.9% at OMC when compared with untreated MC model flexible pavement.
