    The eastern region, due to its geographic location in particular, has characteristics that make the road infrastructure susceptible to natural risks such as landslides, settlements, collapses and ground instabilities. These conditions directly affect mobility, generating incidences in the economic and social activities that depend on these road systems; therefore, in this experimental research project, a structural evaluation of the pavement is carried out, through studies of: soils, hydrography and the identification of geological faults, in order to mitigate the risk of accidents caused by the high rainfall characteristic of the eastern area under study. The investigation began with a visual recognition of the study point, observing the geography and topography of the analysis area. During this stage, the presence of a settlement on the roadway could be seen, so the georeferenced topographic survey was carried out, allowing a specific assessment of the relief and shape of the terrain. Likewise, samples were taken for the study of soils by means of test pits, finding a greater presence of coarse material. These samples were later transported to the laboratory where the corresponding tests were carried out to determine the physical and mechanical properties of the collected soil. The presence of geological faults in the road network was also identified. Likewise, the hydrography of the study area was analyzed. As a result of the evaluation, it was concluded that the settlement detected in the roadway is mainly caused by the infiltration of water into the road network between the aforementioned abscissas. For this reason, a channeling system for surface and infiltrated water was designed as part of the solution to the problem, which includes the use of alternative solutions such as the French drain.
