Erosion is a natural geological phenomenon that occurs in the upper layers of the Earth, but can
be accelerated by man especially when used improperly. A large loss of soil by erosion occurs
on the dirt roads that was diagnosed in the Campo de Instrução de Santa Maria (CISM) where
training occurs with armored vehicles and other large area. This study aimed to understand and
to set the erosive processes on a dirt road located in CISM and how specific objectives sought
to understand how the area used, the type of material involved and its resistance to the process
erosive using for this test of physical characterization and erodibility. The results of this study
may contribute to the maintenance of roads CISM. This research began with a literature review
on the topic, fieldwork for recognition of the area, for description of erosional features and
gathering of samples for be tested through test physical characterization and erodibility. The
sampled points of the road were: the Crust, E2, E6 and E7, and the horizons B and C of the
borrow pit. The tests of the erodibility were performed with the samples E2 , E7 and Crust and
compared to data obtained by Sant Ana, 2012. The road lies over an area of alluvial terrace
where if find argisoil. The road crosses a flat-topped hill with NW-SE direction. Were described
in place, ridges and ravines related to lack of drainage, the presence of compacted layer (crust)
with mud crack, alcoves of the regression, ducts and pot erosion. Geotechnical tests confirm
the fragile nature of local soil, reaffirming human action a accelerator of the erosion in the area. / Erosion is a natural geological phenomenon that occurs in the upper layers of the Earth, but can
