Benefit–cost relationship of using concrete with blast furnace slag as road pavement

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 corresponding benefit–cost relationship were investigated. The prepared specimens subjected to physical mechanical tests following different curing times, it was determined that BFS-added increased peaked at BFS content 20 %. addition, according AASHTO 1993 design method, thickness decreased by 1.58 % 3.38 cost reduced 5.59 10.30
