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 %. © 2023 Union of Croatian Civil Engineers and Technicians.
