Improvement of Lateritic Gravelly Soil Using Cement and Litho-Stabilization and Its Application Case of Main Road Artery on the City Side of the New Ouagadougou-Donsin airport

Abstract

: Innovative techniques like litho-stabilization enhance the quality of lateritic gravel for road construction. Our experiment incorporated varying percentages of crushed gravel with native lateritic gravel. Results revealed that adding 25% and 30% crushed gravel achieved excellent compaction energy, while 20% crushed gravel mixture surpassed natural laterite in density, water content, and plasticity. California Bearing Ratio (CBR) values were notably high, reaching 90%, 95%, and 98% for 20%, 25%, and 30% crushed gravel blends. This research showcases litho-stabilization's potential in fortifying lateritic gravel, yielding resilient and long-lasting road networks.
