Use of recycled concrete aggregate for pavement construction
The recycled crushed concrete aggregates collected from kerb and channel replacement works (K&C-RCA—kerb and channel-recycled concrete aggregate) and from the Hervey Range Landfill (HRL-RCA—Hervey Range Landfill-recycled concrete aggregate) were assessed based on their physical and strength properties as specified by the Queensland Department of Transport and Main Roads (DTMR) for pavement

PCC Recycling – Pavement Interactive
PCC Recycling. Reclaimed concrete material (RCM), sometimes referred to as recycled concrete pavement (RCP), is typically generated by rigid pavement rehabilitation or reconstruction. When crushed, RCM can be used in a variety of ways: As an aggregate in PCC and HMA. As a granular base course. As a fill or embankment material.

Recycled Concrete | Methods of Recycling Concrete | Uses | Benefits
Recycled concrete can be used as an efficient building material, if it is crushed properly and kept free of unwanted materials and contaminants. A process called Rubberization can be achieved through recycled concrete. In this process, the pavement concrete can be broken down in its own place and used as a base layer for the new pavement.
