Resumen
The Nueva Granada Military University and Javeriana University implemented an investigation aimed at determining the viability qfthe use ofwastes generated by the iron and steel industry qf Boyacá (Colombia), with a view to improve thephysical mechanical properties of granular bases and subbases in the constmction of pavements. The tests performed to determine the changes in the mechanical properties qfthe granular material were the standard and modified Proctor and C.B.R. tests As a conclusión, U was established that the resistance índex (C.B.R.) and the density qfthe material increasedby up to a 15%.
