  • Device for measuring and comparing tire to pavement skid resistance
    Patent number: 10241009
    Abstract: A manually operated portable device for comparing tire to pavement skid resistance under different tire to road contact conditions, wherein such device can be used at any location on any pavement type without the need for initial settings. The device can test various parameters, including the effect of tire material on skid resistance, the effect of pavement material, the effect of pavement surface roughness, and the effect of pavement surface conditions, as well as the coefficient of friction. The device may include a plurality of rotating arms, a plurality of shoe assemblies, a central shaft, a stabilizing weight, a square-sectioned shaft, a spring, a handle, and an angular scale.
