TSD

Assessing rut depth, roughness and surface texture with a laser profilometer makes the best use of this quick, efficient technology. In order to improve confidence in this method WARRIP reviewed the approved test methods against…

To fully understand the information produced by the TSD, two sites have been established with embedded sensor arrays. These sensors measure the true motion of the pavement surface when heavy vehicles travel over the test…

Advances in technology now make it possible to collect information about the condition of our roads at speed. The Traffic Speed Deflectometer (TSD) is equipped with doppler lasers, GPS, cameras, temperature probes and 3D sensors;…
