Design and engineering application of SMA-13 steel slag asphalt mixture
In order to further improve the resource utilization level of steel slag in road engineering,five types of SMA-13 asphalt mixtures with steel slag content were designed using the volume replacement method.Their volume stability,high and low temperature performance,and water stability were studied,and experimental roads were paved for verification.The results show that steel slag has advantages such as high strength and wear resistance.Adding an appropriate amount of steel slag can improve the high and low temperature performance and water stability of the mixture.The production,transportation,and compaction processes of steel slag asphalt mixture need to be adjusted based on the original process,and the water permeability,anti slip,and high temperature performance indicators of the paving test section meet the current specification requirements.
