Traffic Speed Deflectometer

Traffic Speed Deflectometer (TSD) is a rolling wheel Deflectometer for network level bearing capacity measurement. TSD uses patented Doppler technology to measure the deflection of roads while travelling at normal traffic speed - up to 80 km/h.

TSD data provides continuous pavement deflection profiles, from which bearing capacity indicies can be derived and pavement fatique / residual life can be estimated. The hign accuracy and resolution makes TSD perfect to pin point location with bearing capacity deviations.
