One of the major relationships being monitored in the stabilization of lateritic soil samples with asphalt-dissolved salt is the variation of the Maximum Dry Density (MDD) in relation to the Optimum Moisture Content (OMC). The influence of the physical characteristics of the selected lateritic soils (samples A – C) on their comparative behaviour in the natural state and their response to treatment with dissolved salt was determined in the laboratory. The percentages of asphalt treated with dissolved salts were 2%, 4%, 6%, 8%, and 10%. Preliminary tests were performed on the three samples A, B, and C for the identification and classification purposely followed by the consistency limit tests. Geotechnical properties tests (Compaction and California Bearing Ratio (CBR)) were also performed on the three samples. It was found that OMC reduced and MDD increased as the asphalt-dissolved salt content increased until it reached maximum at 6%. The relationship between OMC and MDD seems to be a linear one.
