To properly reuse the recycled asphalt pavement after the damage of the BOF slag pavement, the recycled BOF slag is applied to the reclaimed asphalt concrete in this study. Moreover, to increase the applicability and reduce problems caused by the resource dumping site of the recycled BOF slag, the object of this study is to compare the differences between the reclaimed BOF slag asphalt concrete and regular reclaimed asphalt concrete. Results obtained from this study show that the reclaimed BOF slag asphalt concrete has better mechanical properties than that of the regular reclaimed asphalt concrete. The reclaimed BOF slag asphalt concrete has a denser structure and better resilient modulus and creep resistance than that of the regular reclaimed asphalt concrete. It suggests that the reclaimed asphalt concrete with 30% reclaimed BOF slag replacement well performs in different tests.
