Experimental investigation of bottom ash as a capable Soil Stabilizer

Abstract

The development of infrastructure in India is rapidly growing. These structure demands adequate soil as foundation/subgrade but in India where expansive soil cover 51.8 hectare land surface nearly. Stabilization of these expansive is the priority of engineers. Where on the other hand bottom ash from a thermal power plant is directly dumped which contaminatesthe environment. In soil stabilization, a stabilizer is added to soil in optimum quantity to achieve maximum dry density and have minimum penetration. In this study bottom ash's potential is examined as a soil stabilizer and compared with non-conventional stabilizer. Soil is modified with bottom ash at dosages of 10%, 20%, 30% and 40% to inspect the various engineering properties. Atterberg limits (LL, PL, and PI), Compaction characteristics (OMC &MDD) and California bearing ratio test are performed and compared with nano-polymer modified soil samples. Results show that bottom ash can be utilized as a stabilizer for road construction.
