Geotechnical characterization of soils in the northern zone of Brazzaville

The geotechnical classification of soils by laboratory tests is usually used to determine the class soil under study for its subsequent use in construction projects. interest certainly well displayed. Indeed, an experimental program has been developed with aim studying area. To this end, oedometric and shear were carried out on several samples laboratory. This made it possible understand “stress-strain” behavior these soils. As a result, presence silty sand was found that susceptible collapse.
