This research applied geotechnical tests to roads aiming at subsidizing the decision making process for improving the construction and maintenance patterns of access roads. In order to achieve this, characterization experiments (particle size distribution, specific weight of solids, consistence limits), compactation and CBR, in 13 samples of soils were done. The results indicated that, according to the technical specifications of DNER (1996), 2 samples of soils were classified as material for reinforcement of sandy soil, 11 as material to be used in road pavement sub-base and no one sample was considered appropriate for being used in highways base. Therefore, evidencing the need of applying techniques that alter local soil properties, such as, chemical stabilization.
