Expansive soils occupying almost 3 lakh km2 in the Indian subcontinent found to be highlyudproblematic due to their extensive swelling and shrinkage nature. This rapid volume change leads to upliftment ofudfoundations, differential settlements, heaving, rutting, etc. on the overlying structures. Concerning with the aboveudproblems an effective, economical and long-term method lime stabilisation was selected. In this work it is attemptedudto study the effect of curing period on the strength behaviour expansive soil treated with lime and fly ash byudconducting triaxial shear (UU) test for 0, 3, 7, 14, 28 days with some twenty different proportions.
