Road engineering studies involving chemical stabilization of soils deserve special recognition mainly those directed to lowering the costs of forest engineering roads. This work focuses on soil stabilization of a characteristic Latosol from Viçosa, Minas Gerais, Brazil, herein named ETA, using a residue from paper and cellulose industry production, herein called Grits. Grits content of 10% related to soil dry weight was used throughout the study after residue thermal treatment using a furnace at 200, 300, 400, 500 and 600 ºC. Geotechnical standard parameters from compaction and unconfined compression tests were used to evaluate the effect of thermal treatment on the mechanical response of soil-Grits mixtures. Unconfined compression testing data show that Grits is a promising soil stabilizer, mainly after thermal treatment at 600 ºC.
