The geology and geotechnical properties of the black cotton soils of northeastern nigeria
Abstract The paper gives a brief review of the geology of the black cotton soils of northeastern Nigeria. Mineralogical analysis shows the soils to be predominantly kaolinite and montmorillonite. Results presented show low strength characteristics; a soaked CBR of only 1.5%, a residual strength parameter Φr of 12°, and a permeability of 10−10 cm/sec. The plasticity index decreases from 47% to 5%, linear shrinkage decreases from 11 to 3.6% for an increase in lime content of 0 to 9%, respectively. Results presented indicate that a mixture of both lime and cement is necessary for adequate stabilization of road bases for heavy wheel loads on the black cotton soils of northeastern Nigeria. These results are in general agreement with results previously presented for other African and Indian black cotton soils.
