Indirect cost savings from using recycled materials also add up. Recycling concrete pavement prevents the recycled concrete aggregate (RCA) from going into landfills, for example, and, if the recycled material is used locally, can lead to decreased energy consumption and other costs associated with hauling and producing aggregate.
Recycled concrete can be used in many of the same ways as you would use new materials, such as gravel, paving materials, and aggregates. Permeable paving for walkways, driveways, and other outdoor hard surfaces: Broken concrete that is carefully laid creates a stable, porous traffic surface that rainwater can filter through.
