Road Surface Tester

    Dynamic Friction Tester (ASTM E-1911-98) and Circular Track Meter (ASTM E-2157-01) for road surface profiling. Manufactured by Nippo Sangyo Co., Ltd.

    Product Name Main Feature
    Dynamic Friction Tester(DF Tester)
    ASTM:E-1911-98

    Details

    The DF Tester is a portable instrument to measure the frictional characteristics of paved surfaces in laboratories and on field such as highways and airport taxi-ways. The advantage of DF tester is its excellent workability. With one single measurement to depict the friction & speed relationship from high speed to static, no operator influence, and small area operation. It is being used at various institutes in both domestic and oversea such as universities, road companies, automobile / tire manufacturers, etc.
    Product Name Main Feature
    Circular Track Meter(CT Meter)
    ASTM:E-2157-01

    Details

    It is a road surface macrotexture profiler using CCD laser displacement sensor. The Circular Track Meter is designed to measure the same circular track on which the dynamic friction coefficient is measured by DF tester. The C.T. Meter reports the MPD (Mean Profile Depth) and the RMS (Root Mean Square), with which IFI (International Frection Index) can be calculated in combination with the DF tester.
