ABSTRACT: The article characterises the soil of the Limbita 2 plain (Dubréka, Guinea) to assess its suitability for producing adobe bricks. Standard geotechnical tests (particle size distribution, Atterberg limits, modified Proctor, CBR, direct shear, oedometer) were conducted. The results indicate a clay-silt-sand mixture with moderate plasticity (LL ≈ 35.8%, PI ≈ 19.8%), a maximum dry density of 1.80 g/cm3, an optimum moisture content of 17.9%, a CBR value of 11, moderate shear strength (φ ≈ 29.7˚, C ≈ 0.191 bar), and low compressibility. The authors conclude that the soil is suitable for earthen construction, provided that moisture is carefully controlled.
