INFLUENCE OF THE COMPOSITION OF REJUVENATOR ON PROPERTIES OF REPEATEDLY RECYCLED ASPHALT
recycled increasing method adapted to recycling for recycling. For of establishing sustainable asphalt recycling technology, repeated recycling was carried out using several types of rejuvenator having different SARA (Saturate, Aromatic, Resin, Asphaltene) fraction, and the properties of the recycled asphalt and the recycled asphalt mixture were tested. As a result, the following was clarified. The softening point tended to rise due to repeated recycling. Recycled asphalt mixtures using recycled asphalt having a high softening point tended to occur cracking easily at high temperature. Rejuvenators containing a high aromatic tended to suppress an in-crease in softening point.
