    Nippo Sangyo C.T. Meter (Circular Track Meter)
    ASTM :E-2157-01

    The C.T. Meter (Circular Track Meter) is a road surface macrotexture profiler, in which a CCD (Charged Coupled Device) Laser Displacement Sensor is used. It is designed to measure on the same circular track on which theD.F. Testermeasures the dynamic coefficient of friction. There are various methods to characterize road surface macrotexture profiles. The C.T. Meter reports the MPD (Mean Profile Depth) and the RMS (Root Mean Square). The IFI (International Friction Index) can be computed using the C.T. Meter in combination with theD.F. Tester.
