Recycling of Reclaimed Asphalt Pavement (RAP) is the process of recovering aged asphalt and wrapping it around reclaimed asphalt aggregates. RAP can also be incorporated into energy-saving warm-mix asphalt (WMA) technologies. These technologies allow asphalt pavements to be produced at lower temperatures, meaning reduced energy demands and lower emissions during production and paving. WMA additives also serve in a compaction aid capacity allowing for improved densities to be achieved. Aging and hardening of...
