Abstract
Steel slag, a kind of industrial waste, has been considered applying in road construction as aggregate based on abundant indoor tests. The permanent deformation performance of asphalt mixture with Basic Oxygen Furnace (BOF) slag is evaluated by test with UTM-25 and simulation with equations at different temperatures and various stress levels in this study. Results show that the permanent deformation behavior of BOF base asphalt mixture is relatively sensitive to temperature and it can be perfectly modeled with proper equations, otherwise, strain per load cycle of specimen is responsible for mixture failure instead of accumulated permanent strain.
