Summary
The Multi-Speed Deflectometer (MSD) is a new, innovative technique for determining pavement structural capacity and remaining life, at normal traffic speeds.
It combines the efficiency and continuity in relation to testing speed and test spacing of the Traffic Speed Deflectometer (TSD) with the compactness and reliability of the Falling Weight Deflectometer (FWD).
Like the Traffic Speed Deflectometer, the Multi Speed Deflectometer is a network screening device.
However the MSD captures multiple images of the pavement surface during passage of a standard axle and also collects data from multiple sensors, averaging the results to 10 m or 20 m intervals, enabling a near-continuous profile of pavement structural life.
