Road construction using lateritic soil
Abstract The suitability of a lateritic soil developed on olivine basalt in western southeast Queensland, Australia, as paving material has been investigated. The particle size distribution and plasticity characteristics of the soil do not comply with the standard specification for paving materials. However, the soil has a high shear strength, resulting in a low Western Australian Confined Compression Test class number. The high shear strength of the soil at its in situ moisture content is due to its high angle of shearing resistance and its suction under in situ moisture conditions. Volumetric shrinkage of the soil does not constitute a problem as its shrinkage is low. The in situ strength of a pavement constructed with the lateritic soil, determined using a Clegg impact hammer, and the field dry density, have increased with time and the passage of traffic since construction. The pavement performance was good. A criteria suitable for the selection of a lateritic soil as paving material under the climatic conditions prevailing in western southeast Queensland has been suggested.
