Laser measurement of pavement condition on E8 Borealis

Abstract

In 2019, the Directorate of Public Roads in the Norwegian Public Roads Administration (NPRA) aimed to compare various equipment’s for measuring pavement condition and get documentation of the different systems. In addition, the NPRA was seeking the best possible documentation of pavement condition on the E8 test road, both with regard to surface condition (ruts, evenness, damage, texture, etc.) and the structural strength/load-bearing capacity, as well as pavement structure. In total, five suppliers of measurement equipment were invited to accomplish measurements both with laser (scanners and bars), ground-penetrating radar, deflection measurements (load-bearing capacity with FWD, TSD or similar) and picture/video. This report is a documentation of the results from the surface investigations.
