Laboratory Test Study on Asphalt Concrete with Steel Slag Aggregates

To investigate the validity of steel slag as aggregates in road surface dressing, a series of tests for asphalt concrete mixed with asphalt cement and steel slag aggregates particles are performed using Marshall method. Through the statistical analysis of the test data, and comparison the data with those of asphalt macadam mixture, the asphalt concrete mixed with asphalt cement and steel slag aggregates have very large stiffness, high resistance to deformation and high resistance to cracking. If meeting the requirements of the code in china for asphalt macadam mixture, steel slag can be applied in road surface dressing instead of stone aggregates, but also bring remarkable economic effect and has broad application prospect.
