Full Depth Reclamation (FDR) is a process in which the existing worn-out pavement is excavated and recycled to reconstruct the new pavement structure. It is used when pavements are severely distressed and need to be removed and replaced. The deteriorated asphalt is pulverized, mixed with cement and water, and then compacted to form a stronger road base. The new road base is then overlaid with a new layer of asphalt concrete, completing the reconstruction of the road. FDR has cost savings of 30-40% and a lower construction time in comparison to traditional methods.
