Geophysical Investigation of Road Failure: A Case Study of Gedo-Ijaji Asphalt Road, Oromia Regional State, Ethiopia
Author(s): Hika Negeri Feyisa* and Fekadu Tamiru Gebissa
Road failure is widely known in developing countries that cause the loss of many resources due to lack of scientific studies before the construction starts. Thick clay soils, fractures and shallow groundwater are the inducing factors for the failed road segment. Two-dimensional electrical resistivity imaging and magnetic methods were used to map the subsurface lithology and subsurface geological structures that cause Gedo-Ijaji asphalt road failure in Chelia Zone, Oromia, western Ethiopia, in order to solve such serious problems. The lithological units of each geoelectric layer within the study area was studied and interpreted using six profile electrical resistivity imaging and six magnetic profiles with a total data points of 123 collected along the two sides of the asphalt roads and perpendicular to the asphalt road. The electrical resistivity tomography data were processed and inv.. View More»
