Abstract - In civil engineering, the foundation is critical for any land base construction and must be able to withstand the incoming loads without failing. In some areas, the soil may be poor and unable to withstand the incoming stresses. Soil stabilization is required in such circumstances. Redsoilcovers 10.6% of the Indian geographical area. Thecolourofredsoilis due to a high percentage of iron in the soil. Red soil is used in this research. In this research an attempt to study various geotechnical properties and improved the red soil properties by adding different percentages of polypropylene and lime.

In this study red soil is collected and transported from the district of Jalgaon in northern Maharashtra. For this study we take polypropylene as 0.5%, 1%, 1.5% and constant 4% of Lime added to the soil.

Key Words: Soil stabilization, Red Soil, Polypropylene, Lime,CBRetc.

2. MATERIAL USED

Inthisstudy,thefollowingmaterialswereused:

i) RedSoil

ii) Polypropylene

iii) Lime

2.1 RED SOIL

The soil sample for this study was taken in the district of Jalgaon in northern Maharashtra. The earth is a bright crimsoncolor.Redsoilisatypeofsoilthatformsinwarm temperatures and is common in damp climates with deciduous or mixed woods. The red soil's texture ranges fromsandytoclay,withloamaccountingforthemajorityof it.

2.2 POLYPROPLYENE

Polypropylene's starting material is nonnumeric C3H6, a completely hydrocarbon compound. Polypropylene fibers have particularly beneficial qualities due to their form of polymerization,highmolecularweight,andthewaytheyare processed into fibers. Polypropylene fiber is a single fiber withadiameterof0.034mmandcomesinlengthsof6mm, 12mm,and20mm.

4. METHODOLOGIES

Forthisstudywetakepolypropyleneas0.5%,1%,1.5%and constant 4% of Lime added to the soil and done the experiment on red soil. In Laboratory we have done experiments on Atterberg Limit (Liquid limit and Plastic limit),CompactionTest,CaliforniaBearingRation(CBR),and UnconsolidatedUndrainedTriaxialTest(UUtriaxialtest).

5. TEST RESULTS AND DISCUSSIONS

5.1 Effect of Polypropylene and Lime on Heavy Compaction on Red Soil

2.3 Lime

Limeisalsoknownascalciumoxideandhasthechemical formula CaO. It is manufactured by heating Calcium carbonate (CaCO3). When lime is being used in soil stabilization process, it primarily increases strength and minimizesswellsandshrinks.However,moreadditionsmay reducesoilplasticity,andexcesslimeapplicationpromotes brittlefailure,atypeofsoilfailurethatresultsinarapidand significantlossofstrengthwhenithappens.ThePercentage oflimeusedinthisexperimentisconstantat4%.
