NY Materials

Asphalt pavements are 100% recyclable. In fact asphalt is the most recycled product in the United States. So any asphalt that is already in place on a particular site can be delivered back to the plant and reused in the fresh asphalt for the project. A project can get LEED credits for this reuse along with reducing the demand for virgin materials.
