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; all working together on a heavy vehicle to collect vast amounts of information whilst travelling at a highway speed of 80 km/h. Information collected replaces tests that required low speed or stationary vehicles. WARRIP conducted a trial to validate this test collection method and equipment, finding that this TSD method delivered useful information. Cracking, deflection, roughness and rutting data was processed.
