The apparatus is suitable for both site and laboratory applications to perform two types of tests;

• For measuring pavement (road asphalt) surface frictional and skid resistance properties.
• For polished stone value tests on aggregates (curved specimens) from accelerated polishing tests.

The skid tester is also suitable to perform tests on:

• Natural stones conforming to EN 1341, EN 1342.
• Concrete block pavers conforming to EN 1338.

The tester measures the energy loss when a rubber slider edge is propelled over the surface under test.
The height adjusting system is simple and reliable.
The pointer, made from light alloy, has extremely low frictions granting high precision results.
The release mechanism of the pendulum arm has an original solution reducing the friction to minimum for better accuracy.
