摘要：	A four lane divided urban road is proposed for the construction, which is passing over a Municipal Solid Waste (MSW) dump of about 400 m long, Siddharth Vihar, Ghaziabad (U.P.). MSW has heterogeneous composition and settlement may prolong for long duration due to decomposition. Therefore, thorough investigation is needed before construction of road. Accordingly, sub soil investigation of MSW was carried out which included: Standard Penetration Test (SPT), Dynamic Cone Penetration Test (DCPT) and Plate Load Test (PLT). Geotechnical characterization of undisturbed and disturbed samples of MSW was carried out in the laboratory. Expected primary and secondary settlements of MSW dump due to self weight and traffic loading is estimated using field and laboratory test results. It was observed that MSW dump is in saturated condition and depth of dump is varying from 4.5 m to 6.5 m. The average N value of SPT/DCPT was observed to be less than 10. MSW fill is observed to be in loose state and consist of soil, plastic, polythene, cloth, wood etc. The value of coefficient of compression index is more compared to conventional soil. Different remedial measures were suggested before the construction of road over compressible MSW dumps viz. Excavation and Removal of MSW dump, Dynamic compaction with interconnected block pavement and dynamic compaction with stone column
