 | Traffic Speed DeflectometerTraffic Speed Deflectometer (TSD) is a rolling wheel Deflectometer for network level bearing capacity measurement. TSD uses patented Doppler technology to measure pavement deflection while travelling at normal traffic speed - up to 80 km/h (50 mph) TSD data provides continuous pavement deflection profiles, from which bearing capacity indices can be derived and pavement fatigue / residual life can be estimated. The high accuracy and resolution makes TSD perfect to pin point locations with bearing capacity deviations. This information allows you to plan exactly from where to where to repair. TSD can be combined with subsystems collecting functional data simultaneously and synchronized with structural data. |
