Case Study: Increasing the Percentage of Recycled Asphalt
This chapter presents a case study to increase the percentage of reclaimed asphalt (RA) in asphalt mixture by using rejuvenator and to characterize the quality of such a mixture. The effect of rejuvenator was determined on laboratory‐ and plant‐prepared samples. In laboratory, one can prepared asphalt mixtures containing different percentages of RA and rejuvenator. The mixture without RA is control mixture, made only with virgin raw materials. In asphalt plant, one can prepared asphalt mixture with highest content of RA and control mixture. The author conducted different tests, e.g. determining softening point, Fraass breaking point, penetration and indirect tensile strength. Asphalt containing RA was successfully produced in ordinary batch asphalt plant with no special hardware, such as parallel drum. Results showed that asphalt mixture containing RA and rejuvenator fulfilled the technical standards, and the quality was in most cases even better than asphalt mixture made from virgin materials.
