Reclaimed asphalt (RA) is the industry’s answer to environmental sustainability. Here you will gain an understanding of the use of RA from removal to stockpiling of unprocessed RA and avoiding moisture ingress, to crushing, screening and fractioning, stockpiling processed RA, and finally optimising its use.
