Asphalt Recycling How is Asphalt Paving Recycled

For hot mix asphalt, the mixture is tumbled and heated for approximately 20 minutes before it is ready for use. Cold recycling, on the other hand, avoids the use of heat and saves energy in the process. Often, the asphalt cement (the glue that holds the pavement together) retains its adhesive capabilities and can be reused as a binding agent.
