摘要：AbstractThe paper discusses the results of a laboratory evaluation and a theoretical study on the fatigue behaviour of bituminous mixtures with Reclaimed Asphalt Pavement aggregate and electric arc furnace steel slag, used in different proportion.The experimental investigation was performed with the four-point bending test. The fatigue life has been evaluated by three different approaches, based on the 50% reduction of the initial stiffness modulus, the dissipated energy and the damage accumulation.With respect to the reference mixture, composed by a natural aggregate skeleton, the bituminous mixtures with RAP aggregate and steel slag have presented improved fatigue properties and performance.
