The nondestructive measurements are based on pulse induction technology. However, a prerequisite is the installation of a metallic reflector (antipole) of aluminum or steel at the base of the pavement layer to be measured. Layer thickness can be determined directly during paving (self-monitoring) or later as part of control inspections (external monitoring) performed for acceptance of construction work. To take a measurement, the MIT-SCAN-T3 is run over the measuring site. Within seconds, it accurately determines layer thickness. This way, based on a larger number of measuring sites, pavement thickness can be measured extensively and effectively.
