This paper presents a technical and environmental feasibility study carried out with four samples of degraded rail ballast, obtained after the clearance operation, on a railroad in the northern region of the country. Samples were collected at four different points along the railroad. The objective of this work is to know the properties and chemical composition of the degraded ballast material considering the possibility of using it as an alternative aggregate in the base layer of road pavements. For this, tests of physical characterization, chemical, mechanical and environmental classification of the material according to NBR 10004 were performed. The results were satisfactory, and indicated that it is a viable material for road paving purposes.
