Introduction The objective of this paper is to upgrade expansive soil as a construction material using rice husk ash (RHA) and flyash !hich are !aste materials" Remolded expansive clay !as blended !ith RHA and flyash and strength tests !ere conducted" The potential of RHA#flyash blend as a s!ell reduction layer bet!een the footing of a foundation and subgrade !as studied" In order to examine the importance of the study a cost comparison !as made for the preparation of the sub#base of a high!ay project !ith and !ithout the admixture admixture stabili$ati stabili$ations" ons" %tress %tress strain strain behavior behavior of unconfined unconfined compressiv compressivee strength strength sho!ed that failure stress and strains increased by &' and *' respectively !hen the flyash content !as increased from ' to +*" ,hen the RHA content !as increased from ' to &+ -nconfined .ompressive %tress increased by /0 !hile .1R improved by 20" Therefore an RHA content of &+ and a flyash content of +* are recommended for strengthening the expansive subgrade soil" A flyash content of &* is recommended for blending into RHA for forming a s!ell reduction layer because of its satisfactory performance in the laboratory tests"

+"
The common common soil soil stabi stabili$ li$ati ation on techni techni5ue 5uess are becomin becoming g costly costly day by day due due to the rise of cost of the stabili$ing agents like cement lime etc" The cost of stabili$ation may be minimi$ed by replacing a good proportion of stabili$ing agent using RHA"
