The use of EAF steel slags in hydraulically bound mixtures for road foundations: a laboratory characterization
The paper discusses the results of a laboratory study to verify the suitability of a particular type of EAF (electric arc furnace) steel slag to be recycled in the lithic skeleton of cement bound granular material for road pavements. The experimental trial has been articulated in a preliminary study of the physical-geotechnical properties of the EAF steel slag by itself, and in a mechanical characterization of the hydraulic bound mixtures. The formulation of the mixes has been done in terms of Proctor, compression and indirect tensile tests. At the end of the study the resilient behavior of the mixtures has been investigated through cyclic triaxial tests. The results have been extremely positive (compression and indirect tensile resistance at 7 days equal to 3.96 MPa and 0.27 MPa respectively), putting in evidence the possibility to use the EAF steel slags in integral substitution of the natural aggregates, also with low binder content, so reducing the production costs of the mixtures.
