RAP for Cold Recycling
The term ‘RAP’ is given to bituminous material that is recovered from an old existing pavement. There are two ways that RAP material can be used in road construction:
- In-situ Treatment : The existing bituminous mix can be reclaimed and simultaneously treated using ‘cold in-place recycling’ technology (also referred to as CIR or partial depth recycling). This process uses a large truck-mounted recycler to recover the upper portion of bituminous layer of the existing pavement (normally between 100mm to 150mm depth) and simultaneously RAP in mixed with additives.
- In Plant Treatment : The milled bituminous mixture is stockpiled locally and treated in a suitable mixing plant. The treated RAP material is then returned to site and paved back in the areas that were milled. The ‘cold in plant recycling’ technology introduces flexibility into the recycling process by separating the recovery and reuse operations. In addition, where required, this process provides the opportunity to crush and/or screen RAP material as well as blend it with fresh aggregate. (eg. Graded crushed stone), if required, before it is recycled.
