| dc.description.abstract | This work investigates probable changes during repeated heating and cooling cycles on some index and engineering properties of some lateritic soils. Bulk soil samples were taken within Ilorin metropolis. These samples were oven dried for 24 h at 110 oC and cooled naturally to room temperature. This procedure was repeated four times. The effect of cyclic heating and cooling on various soil properties including Atterberg limits, particle size distribution, moisture— density relationship and California bearing ratio (CBR) were investigated. The results show that maximum dry density (MDD) reduced consistently with repeated heating and cooling while optimum moisture content (OMC) increased. CBR increased with repeated heating and cooling up to 23.5%. A percentage decrease in liquid limit up to 25% was recorded while plastic limit and plasticity index reduced in all samples. Increase in CBR is an indication of increase in strength with repeated heating while the decrease in MDD is an indication of reduced density on account of increase in OMC of the soil samples with repeated heating. | |
