Recycled, Co-Product, Waste Material - What's The

Recycled Materials. Recycled materials are obtained from an old pavement and are included in materials to be used in the new pavement. Common recycled materials include reclaimed asphalt pavement or recycled concrete pavement. Depending on the regional market, these materials would be "waste" if not recycled, ending up in a landfill.


However, some quantity of such waste is being recycled and utilized in building materials and share of recycled materials varies from 25% in old buildings to as high as 75% in new buildings [2, 3,]. Hence the subject of concrete recycling is regarded as very important in the general attempt for sustainable development in our times.
