LT - BM: pendulum friction coefficient tester is a dynamic pendulum impact type instrument. It is developed according to the basic principle that "the potential energy loss of the pendulum is equal to the work done by overcoming the friction of the road surface when the rubber sheet at the end of the swing arm slides on the road surface".
The pendulum friction coefficient tester offers advantages like portability, simple operation, high measurement accuracy, and wide applicability for on-site testing of pavement friction properties.

Here are some frequently asked questions (FAQs) about pendulum friction coefficient tester:
The tester features a standardized pendulum mechanism and precise calibration procedures. Its readings maintain high consistency within ±2 BPN (British Pendulum Number), ensuring reliable data for surface friction evaluations.
Yes, it is very versatile and suitable for all kinds of pavement, including asphalt, concrete, and even textured or polished materials. Just make sure that the surface of the road markings is clean and dry to make accurate measurements.
A single test usually takes less than 5 minutes. This includes setting up the tester, conducting the pendulum swing, and recording the reading, making it an efficient option for quick on-site assessments.
Calibration is relatively straightforward. Regular checks with a standard calibration block are sufficient, typically done quarterly or after significant impacts. The process is detailed in the user manual, enabling operators to handle it easily.
Its portability and manual operation make it ideal for remote or hard-to-reach sites—no power supply is needed, and the compact design allows easy transportation. This makes it a go-to choice for rapid on–site friction assessments in various field environments.
