2014-11-15  The use of recycled aggregate has been found to be better than that of virgin aggregates for certain applications. For example, the physical properties of recycled aggregates make them ideally suited for road base and sub-base. This is because of their physical properties which means less cement is required making them suited for sub-base use.
