The British pendulum test is commonly used to measure low-speed pavement friction and provide a measure of the quality of pavement surface micro-texture in terms of skid resistance contribution.
The tester measures the energy loss when a rubber slider edge is propelled over the surface under test. The release mechanism of the pendulum arm has an original solution reducing the friction to a minimum for better accuracy. The skid tester is supplied complete with: Additionally incorporated scale for tests on Polished Stone Value specimens. The British pendulum tester (BPT) and the dynamic friction tester (DFT) are commonly used to evaluate the polishing effect of traffic on pavement skid resistance. This Pendulum Test measures something called “dynamic coefficient of friction (CoF)” and is designed to reproduce the same characteristics that occur when a person slips on a contaminated floor. The Pendulum is the preferred test method for assessing pedestrian slip risk in the United Kingdom. It is unique in its ability to replicate the .
