Repairs and reconstructions of asphalt roads and paved areas generate largeamounts of construction debris in the form of reclaimed asphalt pavement(RAP). The material milled from the upper layer contains aggregate andasphalt with deteriorating performance parameters as a result of long-termservice under variable weather conditions. Since the debris is mostly composedof non-renewable materials, attempts have been made to recycle and utiliseit in the preparation of new asphalt mixtures. This study investigates thedesign of an asphalt mix containing recycled RAP and summarises the testingof its performance parameters. By lowering the mixing temperature andusing a two-stage method of RAP heating, it was possible to design an asphaltmix with 90% RAP content; thus, the demand for virgin aggregate and thefuel consumption throughout the mixing process could be effectively reduced.
