Continuous Friction Coefficient Tester
Description
This friction equipment is designed for both functional (maintenance) and operational testing to evaluate surface friction including changes due to weather contaminants and rubber contamination. Operational friction testing can be performed during such adverse weather as heavy rain, ice, slush or snow. Determining and maintaining acceptable pavement friction condition is highly important to airports and roads authorities. Low friction values may lead to fatal accidents that pavement engineers work diligently to avoid.
This friction equipment adopts special tyre to measure the resistance force, to some extent it's the fast way to measure; .
