Consists of an adjustable pendulum arm, and a spring loaded rubber slider (see accessories) mounted on the end of the arm. Used for the measurement of surface friction properties, the apparatus is suitable for both side and laboratory applications and for Polished Stone Value (PSV) using curved specimens from accelerated polishing test with the Accelerated Polishing machine. During operation the pendulum is raised and then allowed to swing freely, allowing the edge of the rubber slider to skid across the surface of the road or sample.

The pendulum is supplied complete with:

Washing bottle, 1 l cap. for surface wetting

Tool set with case for machine assembly

Additional scale for tests on Polished Stone Value specimens

Thermometer 0 to 220°C for surface temperature measurement

Rule for sliding length verification

Carrying case

Main Features:

Slider lifting system integrated in the pendulum foot that guarantees reliable adjustment operations

Stiff and stout twin column structure

Easy and reliable height adjusting system

New low friction release mechanism of the pendulum arm for biter accuracy

Extremely light pointer, for high precision results.

Integrated additional scale for tests on PSV specimens
