A113 Skid Resistance and Friction Tester

( Asphalt Asphalt Aggregates-Rocks )

  • EN 1097-8
  • EN 1338
  • EN 1341
  • EN 1342
  • EN 13036-4
  • ASTM E303
  • EN 1436

Designed for both laboratory and in-situ applications, this tester is essential for measuring surface friction and skid resistance on various materials. Whether you're assessing road asphalt, polished stone specimens, or paving blocks, the device ensures high-precision, repeatable results thanks to its low-friction pendulum system and refined height-adjustment mechanisms.

The tester is particularly suitable for:

  • Pavement surface evaluation on roads and highways

  • Polished Stone Value (PSV) tests on curved aggregate specimens

  • Natural stone and concrete paver friction assessment in compliance with EN 1341, EN 1342, and EN 1338

Its compact design and robust transport case make it ideal for mobile professionals, while the included accessories simplify test setup and execution.

Note: The tester is supplied calibrated according to EN 1097-8.
On request, it is also available pre-calibrated for ASTM E303 (see model A113-01).
Rubber sliders must be ordered separately (see accessories).
