Most recycled concrete is used as aggregate in road sub-base. When well cleaned, the quality of recycled concrete aggregate is generally comparable to aggregate. The possibilities for use are equally comparable although the use of crushed concrete in new fresh concrete is rare. Recycled aggregate accounts for ~6% to 8% of aggregate

How Concrete Is Recycled. Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate. Additional processes and equipment, such as water ...
Concrete recycling allows for the reuse of the rubble while also keeping construction costs down. It is a cost effective alternative for stone base material. Recycled concrete is very compactable, which makes it ideal for a base material under asphalt, concrete, paving stones, or stone driveways.
