“Delamination” refers to a condition that occurs between asphalt layers underneath a roadway that can lead to surface pavement cracking and tearing – a problem due to asphalt layer “de-bonding” or stripping, which engineers can’t see, especially in the early stages.
A new solution to this problem developed through the SHRP2 program is called Advanced Methods to Identify Pavement Delamination, commonly referred to as R06D. It features two non-destructive testing technology systems that can spot problems in the asphalt pavement beneath the surface in a safer, faster, and less expensive way than previously done.
