Recycling concrete can be done in two ways either by transporting it to a quarry to be crushed, or on-site using a mobile concrete reclaimer such as the Rapid Reclaimer. There are pros and cons to both methods. On-site recycling costs less and causes less pollution than the option of transporting elsewhere.

In this process, the pavement concrete can be broken down in its own place and used as a base layer for the new pavement. Larger pieces of crushed recycled concrete can be used for Riprap revetments, which are a very effective and popular method of controlling erosion.
