Skid Resistance Tester
Application
The apparatus is used to measure antiskid performance of high grade
roads and airport pavement both in lab and in-situ. It is convenient in
operation, and with precise testing results, stable performance.
Structure
1. Foundation: composed by T type legs, levelling screws, and bubbles.
2. Upright column: composed by one column, one lifting unit, one guiding rod
and one handle.
3. Releasing switch: fixed on the cantilever, used to remain level of pendulum
rod and release pendulum.
4. Steering system: including one tightening handle, one pendulum shaft, one
knuckle and one bearing, the whole system connects the pendulum,
secures its position and ensure free oscillation in the plane.
5. Scaling system: Including needle felt gasket, clamping cap, needle adjusting
screw and dial gauge. BPN is read directly from what the needle points.
6.
Pendulum: composed of upper and lower connectors, oscillation rod,
spring, lever, lifting handle, hammer shell, slipping chunk and rubber
chunk(76x25.4x6.35mm).
