摘要：Procurement of conventional materials in huge quantity required for construction of Subgrade of road isbecoming very difficult in many locations due to various problems. On the other hand due to increasing economicgrowth & industrialization, a huge quantity of waste materials generated needs land for disposal & from that generallycreates problems for public health & ecology. So need has arisen for proper disposal of the waste materials. Studybrings out the effect of siliceous compound available in amorphous form in burnt Rice Husk Ash, when different dosesare mixed with weak soil increases the subgrade strength characterstics. Geotechnical engineering properties likeLiquid limit, Plastic limit, Compaction characteristics, CBR values of soil have been studied in this work. On additionof Rice Husk ash the diffused double layer thickness of mixture increases and hence water holding capacity of soilmixtures increases. Specific gravity decreases on addition of ash. On addition of Rice Husk ash the gradation ofmixture is adversely affected which leads in reduction of dry density. Rice Husk ash can be used as a good stabilizeralong with lime.
