Abstract
This paper presents the Black cotton soil is susceptible to detrimental volume changes due to variation in moisture content. A clay mineral named Montomorillonite which has expanding lattice is responsible to such behavior of this soil. Because of its special structure and properties it is subjected to appreciable volume changes. The term expansive soil applies to soils that have the tendency to swell when their moisture content is increased and shrink when their moisture content is decreased. The moisture may come from rain flooding, leaking water or sewer lines or from reduction in surface evapotranspiration when an area is covered by a building or pavement. To achieve this problems the total soil is replaced with fly ash and stabilized with palm oil fuel ash & jute fiber in proportion manner.fly ash stabilized with POFA in regular intervals of 6%,10%,14%,18%..... etc. jute is added in length of 3cm,6cm,9cm with 0.5%.1%,1.5% by weight.The combined effects of two materials POFA and JUTE FIBRE on compaction characteristics, California bearing ratio (CBR).
