Jan 20, 2020 · Hot-Mix Asphalt . Studies indicate that the use of a small percentage of recycled asphalt shingles (RAS) in hot-mix asphalt helps improve the performance of pavement by reducing rutting and cracking. Because RAS substitutes for more expensive virgin asphalt cement and aggregate, it lowers the overall cost of hot-mix asphalt.
What is Recycled Asphalt? | Pavement Recyclers
Cold Mix Asphalt. Recycled cold mix produced at a central RAP processing facility requires similar materials as hot mix asphalt. However, in cold mix asphalt the graded RAP incorporates into paving mixtures as an aggregate substitute. Conversely, cold mix asphalt produces on-site (or in-place) involves special plants (or processing trains).
