Stabilization of Clayey Soil by Using Stone Dust and Plastic Bottle Strips in Subgrades

Abstract

The main intention of this study is to enquire the use of waste stone dust and plastic bottle fiber as newlinestrips in the stabilization of clayey soil in the sub grade and to evaluate the effects of stone dust and newlineplastic fiber on geotechnical properties of soil. Soil stabilization improves the engineering properties newlineof weak soil by adding stabilizer like cement, fly ash, rice husk ash, lime, allcofine etc. in this study newlinethe stone dust and plastic fiber are used as a stabilizer. stone dust is a kind of solid waste material newlinewhich are easily available from stone crusher and stone dust is one which is formed in large quantity newlineabout 15% 25% of the total production in each crusher unit is left out as the waste materials. Plastic newlinebottle are also solid waste material which are day by day increasing and not in environmental friendly newlinehence they have to be recycled and to be used for soil stabilization. In this study of stabilization of newlineclayey soil, The various percentage of stone dust is taken as 2%,4%,6%,7%,8%,10%12%,16%,20% newlinewhich were passing from the IS sieve 150 micron. After performing work on these percentages one newlineby one the optimum value obtained is 7% and further test like Standard Proctor and CBR is to be newlineconducted on this optimum value by using plastic bottle strips. The plastic was taken 0.4%, 0.8%, newline1.2%, 1.6%, and 2.0%. The optimum percentage of 7% stone dust and different percentage of plastic newlinestrips is mixed with soil sample as to explore the effects of mixing on the OMC, MDD, swell index newlineand CBR properties of soil. newline newline newlineiv. newlineI would also like to thank Manish Kumar Soni, Manish Chauhan, Anu Thakur, Aarti Dhamija newlineand Supriya who have been associated with me during this dissertation work. newlineFinally, a special thanks to my family. Words cannot express how grateful I am to my father, mother, newlinemy sisters, for all of the sacrifices that they ve made on my behalf. Their prayers for me was what newlinesustained me this far. I would also like to thank all of my friends who supported me in writing and newlineincanted
