Experimental study on the use of crushed granite sand for lithostabilization of lateritic soils in road construction
Yasmine Binta Traoré, Possibo Elise LOMPO, Nafissatou Savadogo, Hamma Fabien Yonli
The use of local materials in road infrastructure provides a sustainable alternative to the high costs of conventional construction materials. However, certain lateritic gravels exhibit insufficient geotechnical properties for direct use in pavement layers. This study evaluated the potential improvement in the physical and mechanical propertie(...)

Valorization of Local Resources for Sealing of Mining Facilities: Characterization of A Geosynthetic Clay Liner Using Clay and Kenaf Fibers from Burkina Faso
Médaninpo Fidèle Yonli, Hamma Fabien Yonli, Gounwendmanaghré Hubert Zongo, Dieudonné Tankoano, Emmanuel Nikièma, David Yemboini Kader Toguyeni
Since the early 2000s, Burkina Faso has experienced significant growth in the mining industry, generating large quantities of waste that require strict management in dedicated facilities. To limit pollutant migration in these mining sites, imported manufactured materials such as Geosynthetic Clay Liners (GCLs) and geomembranes are commonly use(...)

ESTIMATION DES TASSEMENTS DIFFÉRENTIELS DES SOLS DE FONDATION DE BÂTIMENT : CONTRIBUTION DES SONDAGES DE RÉSISTIVITÉ ÉLECTRIQUE
Hamma Fabien Yonli, Gilbert MANO, Mahamadou Koïta, Aristide COMPAORE
To estimate differential settlements of building foundation soils, the site on which the structure is based must be geotechnically surveyed in order to determine the deformation parameters and the thickness of the compressible soil layers in various places. This involves conducting destructive surveys. In this study, the use of geophysical met(...)

Slope Stability Analysis: Case of the West Wall of the EMZ Pit at the Essakane Gold Mine in Burkina Faso (West Africa)
Hamma Fabien Yonli, Michée Banyua Lompo, Nicolas Kagambega, Pierre Sawadogo
Knowledge of the state of stability of mining pits is both a basic condition, an essential axis and a safety benchmark for mining operations. This stability is largely based on the knowledge of the rock mass sheltering the mining works and this requires a perfect characterization of all of its structural formations through mapping (manual or d(...)

Study of the rheological properties of clayey suspensions: an interest in the field of landfills
Hamma Fabien Yonli, Anne Pantet, David Yemboini Kader Toguyeni
In the landfill bottom liners design process, geotechnical tests of long duration time are often conducted to ensure the presence of reactive clays and to assess their hydromechanical properties. This study aims to show the interest of the rheometry of clayey suspensions as an alternative tool for identifying clays and determining the shear st(...)

Contribution of Electrical Resistivity Tomography to the Anticipation of Potential Disasters: Case of Pipe Ramming Works Under Road Embankments
Hamma Fabien Yonli, Mahamadou Koïta, Issouf Kanla, Aristide Compaoré, Gilbert Mano
Throughout Burkina Faso's road network, some roadways have experienced subsidence or collapse following pipe ramming works conducted for the laying of pipes such as drinking water supply networks.When such works are conducted, it is difficult to make a diagnosis of the properties of the formations underlying the road embankment because a destr(...)

Thermal Effect of Braking on Pavements during Heat Waves in Ouagadougou
Sidpouita Mathilde Koudougou, Hamma Fabien Yonli, Moussa Sougoti, David Yemboini Kader Toguyeni
Flexible pavements, whose surface layers are made from hot mix asphalt, may show rutting in some of these infrastructures during the first months of life. In the city of Ouagadougou, this rutting phenomenon is sometimes observed. The objective of this article is to quantify the thermal response of the wearing course of national roads 1 and 2,(...)

Hydrogeophysical Characterization of a Fractured Aquifer by Using Cumulative Resistivity Method: Case Study of Obuasi Aquifer (Ghana)
Hamma Fabien Yonli, Mahamadou Koïta, Younaise Sounkanmi Olouwachéyi Adéotan, Elisabeth Darko
Knowledge of the structure and geometry of aquifers is an important prerequisite when one wishes to sit a borehole. Such knowledge is currently obtained by VES (Vertical Electrical Soundings) whose interpretation is not always unequivocal in the sense that several resistivity models derived from VES can explain the same data set. The present s(...)

Hydro-mechanical behavior of two clayey soils in presence of household waste leachates
Hamma Fabien Yonli, Bertrand François, David Yemboini Kader Toguyeni, Anne Pantet
BACKGROUND AND OBJECTIVESIn landfills, containment is provided by natural or artificial clayey materials known for their low permeability and for their pollutant retention capacity. However, the properties of these media are modified by leachates, whose migration they are supposed to limit. This study aims to reconsider the criteria for choosi(...)

Mahamadou Koïta, Hamma Fabien Yonli, Donissongou Dimitri Soro, Amagana Emmanuel Dara, Jean‐Michel Vouillamoz
This study aims to estimate the groundwater storage change of hard rock aquifers in the face of change. For this, the approach developed consisted initially in the implementation of 5 Magnetic Resonance Soundings (MRS) around the observation wells realized and monitored from 2014 to 2015 in the Sanon experimental site. In a second step, we det(...)
