Ex-situ and In-situ Manufacturing Procedures for Optimizing the Characteristics of a Soil Concrete Based on Lateritic Gravels and Granitic Aggregates: Application in Road Construction

A methodology of in-situ mixing of soil concrete in a quarry has been proposed to guarantee the required characteristics after implementation. The manufactured soil concrete is a mixture of granitic aggregates and lateritic gravels. Geotechnical tests were used to determine the physical and compacti...

Description
Summary:A methodology of in-situ mixing of soil concrete in a quarry has been proposed to guarantee the required characteristics after implementation. The manufactured soil concrete is a mixture of granitic aggregates and lateritic gravels. Geotechnical tests were used to determine the physical and compaction characteristics of the studied materials. The results obtained show that the rocks encountered in the Gamboula area are granites with good to excellent impact resistance (LAA
