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 %.eninfo:eu-repo/semantics/openAccessroad pavementblast furnace slagvery weak bearing strength soilconcrete slabAASHTO methodArticle751233710.14256/JCE.3570.2022WOS:001710597200001Q40000-0002-6385-0964
