[VIDEO] How State DOTs Are Working to Fix Pavement Delamination

SHRP2 supports development of tools that help transportation agencies detect location and severity of asphalt “delamination” under road surfaces

“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.
