Abstract(s)This paper focuses on the study of the influence of different RAP preparation procedures, prior to the production of a recycled asphalt mixture, on the success of the manufacturing process. A 50% recycling ratio was used in order to test if a high level of RAP incorporation could be achieved by an adequate control of the production process. It was concluded that when an adequate size reduction and separation procedure is used, mixtures with better quality can be obtained since the mix design specifications can be achieved more easily and the binder of the final mixture is less aged by the high temperatures.
