Road deformation monitoring and event detection using asphalt-embedded distributed acoustic sensing (DAS)

Distributed acoustic sensing (DAS)….is opening a new field of research of examining very small strains in infrastructure….study's results demonstrate that φ-OTDR can be used to quantitatively measure strain in roads associated with events as small as a dog walking on the surface.
