摘要

This study focuses on how the voids in mineral aggregate (VMA) and performance of dense grade asphalt concrete (DGAC) are influenced by the 100% replacement of coarse natural aggregates with basic oxygen furnace (BOF) slag. By using different mixture designs to obtain the optimal asphalt content, and then conducting performance tests and analysis of variance (ANOVA) between the test set and the comparison set, this study explores whether the replacement of coarse natural aggregate with BOF slag would reduce the durability and strength of DGAC. The mixture design results show that the BOF aggregates decreased the VMA of hot-mix asphalt; however, laboratory performance tests, especially moisture sensitivity and creep tests, showed that the lack of VMA did not adversely affect the durability of DGAC. Based on these results, 100% replacement of coarse natural aggregates with BOF slag is considered feasible and worthy of further study.
