Özet
In this study, the usability of concrete containing blast furnace slag (BFS; 15, 20, 25, 30 wt.%) as road pavement on soils with weak bearing strength and the corresponding benefit-cost relationship were investigated. The prepared concrete specimens were subjected to physical and mechanical tests following different curing times, and it was determined that the mechanical strength of the BFS-added specimens increased and peaked at the BFS content of 20 %. In addition, according to the AASHTO 1993 design method, it was determined that the thickness of the BFS-added concrete pavement decreased by 1.58 % to 3.38 % and the cost was reduced by 5.59 % to 10.30 %.
