Expansive soils have problems to civil engineers in general and to geotechnical engineers in particular. In India, expansive soils popularly known as black cotton soils are highly problematic, as they swell on absorption of water and shrink on evaporation thereof. Because of this alternate swell and shrinkage, distress is caused to the foundations of structures laid on such soils. There have been many methods available to controlling the expansive nature of the soils. In many countries including India, these soils are so extensive that alteration of highway route to avoid the material is virtually impossible. Various remedial measures like soil replacement, pre-wetting, moisture control, lime stabilization etc. have been practiced with varied degree of success. A methodical process, involving experimentation in the laboratory under controlled conditions is done. It is observed form the laboratory studies that maximum improvement in the properties of Expansive soils for Burnt municipal solid waste treatment with polypropylene fibers in this investigation. A methodical process, involving experimentation on Atterberg limits (liquid limit, plastic limit), Differential free swell, Sieve analysis, specific gravity, Proctor compaction test, California Bearing Ratio(CBR), Unconfined Compressive Strength(UCS) tests were conducted by adding 0.5%, 1%, 1.5% & 2% of Polypropylene fiber to the expansive soil by dry weight under controlled conditions in the laboratory. It is observed from the laboratory studies that maximum reduction in properties is observed for stone dust treatment with Polypropylene fiber. Burnt municipal solid waste is a kind of solid waste material that is generated from house hold waste which is abundantly available. The effect of randomly distributed Burnt municipal solid waste on MDD, OMC, UCS and CBR has been discussed in this project. Polypropylene fiber is an orange to brown-black solid. Polypropylene fiber is non-combustible and corrosive in nature. The percentages of Burnt municipal solid waste by dry weight of soil was taken as 5%, 10%, 15% and 20%. The first series of compaction, CBR and UCS tests were conducted on the Expansive soil and the same tests were conducted in the second series on soil samples mixed with Burnt municipal solid waste and similarly tests were conducted in the third series on soil samples mixed with Burnt municipal solid waste and Polypropylene fiber. Laboratory experiments favorably suggest that mixing Burnt municipal solid waste and Polypropylene fiber with soil would be effective in improving soil properties
