Compressive strenght of steel slag stabilized mixes

The compressive strength testing, conducted on stabilisation mixes with steel-furnace slag originating from the Sisak Ironworks, and on "standard" stabilisation mixes with crushed stone aggregate from "Velika" Quarry, is presented in the paper. The testing was made to check whether slag can be used as aggregate in pavement base courses, and to determine in what way compressive strength values are influenced by binder content and grading of stabilisation mixes. Compressive strength results obtained during this testing comply with stringent criteria set in technical regulations, and confirm that slag can be used in stabilized base courses of pavement structures.
