USE OF LATERITIC SOILS FOR ROAD CONSTRUCTION IN NORTH DAHOMEY

DUE TO THE DETERIORATION OF THE PARAKOU-MALANVILLE HIGHWAY, THE PREPARATION OF A REHABILITATION PROGRAMME WAS NECESSARY. THE RELATED GEOTECHNICAL EXPLORATION PROVIDED AN EXCELLENT OPPORTUNITY TO STUDY THE PROPERTIES OF THE ENCOUNTERED LATERITIC SOILS. THE MINERALOGICAL ANALYSIS PROVED THAT THE LATERITIC OVERBURDEN ORIGINATES FROM THE LOCAL ROCKS. HOWEVER, THE ANALYSES ALSO INDICATED THAT THE SOILS CAN ONLY BE IDENTIFIED AS LATERITIC BY VIRTUE OF THEIR HEMATITE CONTENT. THE SOILS WERE CLASSIFIED ACCORDING TO THE AASHO- SYSTEM AND THEIR GEOTECHNICAL PROPERTIES WERE THOROUGHLY INVESTIGATED. THE RESULTS REVEALED THAT THE OVERWHELMING MAJORITY OF THE AVAILABLE SOILS WAS UNSUITABLE FOR HIGHWAY CONSTRUCTION DUE TO THEIR HIGH PLASTICITY. IN ORDER TO IMPROVE THEM, CEMENT STABILIZATION WAS SUGGESTED. THE LABORATORY TESTS RESULTED IN AN ECONOMICALLY FEASIBLE SOLUTION. /AUTHOR/
