Recycling at the Asphalt Plant: Reclaiming Asphalt and Using It Again Offers Both Environment and Cost Benefits

In a feature on road recycling, the first article discusses some of the conditions that argue in favor of the use of reclaimed asphalt and outlines some of the techniques by which it can be most effectively used. More than 500 million tons of reclaimed asphalt are produced around the world each year, from milling or other methods of breaking up old road surfaces. The price for raw materials for making new asphalt is rising, from $125 per ton to $480 per ton in just one year. If a much higher permissible proportion of reclaimed asphalt is permitted, there will be greater incentives to process it. Three methods are described for how to incorporate it into new pavement. A second article discusses using recycled asphalt in surface course mixtures. Road trials are described, along with estimates of energy savings from using the method. A third article covers a project that used in-situ recycling for a 12,000-sq. meter section of road. The preparatory steps and paving processes are detailed.
