| dc.description.abstract | Steel slag is one of the industry wastes engineered into road construction material. This study was carried out to evaluate the performance of steel slag aggregates as road construction material and its performance compared to granite aggregates. The steel slag aggregates were tested for its physical and mechanical properties. Two dense mix designs incorporating penetration grade 80/100 bitumen and one porous mix design incorporating penetration grade 60/70 bitumen were used to produce the specimens for testing. The dense mix specimens are referred to as 100% Steel Slag Dense Asphalt (SSDA) and 50% Steel Slag 50% Granite Dense Asphalt (SSGDA) while the porous mix specimens are referred to as Steel Slag Porous Asphalt (SSPA). During the first phase of the study, SSDA and SSGDA were tested for performance evaluation through resilient modulus, dynamic creep, Marshall stability and indirect tensile strength. Apart from the tests stated (except for indirect tensile strength), SSPA were also tested for abrasion loss and water permeability. In the second phase of the study, the same tests as those carried out in the first phase were carried out on aged specimens. Resistant against permanent deformation and low temperature cracking improved after aging for both dense mixes and porousmixes. Test results revealed that steel slag inhibits great potential as road construction material. | |
