Abstract
In this study, natural aggregates were replaced with reclaimed asphalt pavement (RAP) from a basic oxygen furnace (BOF) and applied to the base or subbase of roads. The effects of using different levels of RAP BOF to replace the natural aggregates on the properties of the road were investigated. Mixtures of natural aggregates with different contents of RAP BOF (containing 60% BOF slag) aggregates were used, and the results indicate that using a RAP BOF aggregate content up to 40% in the road base satisfies the requirements for the California bearing ratio (CBR) and expansion ratios. The study suggests that the optimal RAP BOF aggregate replacement content is 20%.
