Influence of steel slag stabilized mixtures on pavement stress-strain characteristics

Due to the limitations of empirical methods in pavement structure design, analytical method is applied in order to estimate influence of new materials on pavement stress and strain state. Measured modulus of elasticity for cement stabilized base layer with gravel and steel slag are used for stress and strain calculation using BISAR software. Results show that adding steel slag to cement stabilized mixes with 2% and 4% cement content result in subgrade stress decrease by about 11% and 6% respectively and strain decrease by about 13% and 7% respectively.
