| description | This work evaluates the behaviour of clay soil mixture by adding stell waste/slag, comparering with the quality criteria to be a subgrade road. The behavior of the mixture of steel waste with kaolinite clay was established with a dosage matrix of global increase, in percentages of 25, 50 and 75% through sieve number 4. The results show that the steel waste works on cohesive materials, reducing plasticity by up to 0%, and increasing the California Bearing Ratio (CBR) value, by 378.92%. It is possible to conclude that the steel waste is an excellent complement for improving the physical and mechanical properties of kaolinite clay subgrade. In a first approximation, the most recommended dosage is 25%, because the reduction of resistance to compression and plasticity index was not as high as in other dosages, but it increases the CBR index and the density. |

El presente trabajo evalúa el comportamiento de mezclas de suelo arcilloso mediante la adición de escoria de acero, comparando con los criterios de calidad para ser una subrasante vial. El comportamiento de la mezcla de escoria de acería con arcilla caolinita, se estableció con una matriz de dosificación de aumento gradual, en porcentajes de: 25, 50 y 75%, a través del tamiz N°4. Los resultados indican que la escoria de acería funciona en materiales cohesivos, reduciendo la plasticidad hasta un 0%, y aumentando el valor del California Bearing Ratio, CBR, en un 378.92%. Se concluye que la escoria de acero, es un excelente complementopara mejorar las propiedades físicas y mecánicas de una subrasante de arcilla caolinita. En una primera aproximación, la dosificación más recomendada es de un 25%, debido a que la disminución en la resistencia a la compresión e índice de plasticidad no fue tan alta como en las otras dosificaciones, pero sí aumenta el índice CBR y la densidad.
