Abstract
An asphalt pavement modification system and method for improving aging resistance of asphalt pavement and a method of manufacturing reclaimed asphalt pavement. The asphalt pavement modification system and method include using one or more antioxidants and one or more recycling agents in a blended binder to provide improved short term and long term performance of the asphalt pavement. The method of manufacturing reclaimed asphalt pavement includes mixing at least one antioxidant with at least one recycling agent to form a binder that constitutes a portion of the reclaimed asphalt pavement. One of the antioxidants may be zinc diethyldithiocarbamate.
