To this end, we used two types of swelling clay soils, the first one is intact and the other derivative (reconstituted, prepared from a natural soil and bentonite mixture with the following proportions: 70 and 30%. The results of the recorded oedometric tests show that the incorporation of the lime reduces the soil swelling pressures at each dosing lime in agreement with many reported previous studies. The contents of lime greatly affect swelling; indeed for a dosage of 6% lime the swelling pressures are reduced by 27% for the sample of disturbed soil. The compaction test performed on the reconstituted incorporated lime soil shows that for a dosage of 2% lime, we have a reduction of the swelling pressure of 96%.enexpansive clay soilswelling pressuredosing limecompactionWorking Paper
