    Detailed Product Description
    Standards: ASTM E670-09 Functions: Surface Friction Coefficient Test



    ASTM E670-09, JTG-E60-2008, JT/T752-2009, JJG100-2010; JT/T778-2010


    The Continuous friction tester (CFT) is used to measure the surface friction coefficient of highway or runway of airport.



    The whole system comprised the measuring unit, 3-wheel walking unit, road surface temperature sensor and non-contact environmental temperature sensor, specialized test software, and water-spray system and wheel-lift system can be optional equipped. The 3-wheel trailer is connected to the front tractor through a tow hook to quickly test the road friction coefficient.

    Working principle

    The included angle between CFT wheel and the driving direction is of 7.5°,

    and when driving on a wet road at a certain speed, the lateral friction force

    on the test wheel is compared with the load acting on the test wheel,

    the ratio is called as the lateral force coefficient, and this method is called as the

    deflection wheel trailer method.


    Its advantage is it does not hinder the traffic during the measurement, and

    can be continuously and quickly measured. High-grade highways often uses the CFT

    to evaluate the anti-skid performance of the road surface.


    Features & Advantages

    High sturdy structure and innovative design make the JT-CFT03 can perform road friction coefficient detection under almost all road conditions

    Wide application range, not only meet the road test standards of most countries, also meet the FAA Standard.

    Multi-language option for test software, better meets the operation requirements of different countries and areas.

    Touch screen operation of test interface

    Real time display of parameters: walking speed, test distance, friction coefficient value, SFC conversion value, air temperature

    road temperature; the graph of friction coefficient VS distance

    powerful software functions(see software part)
