This document specifies the performance characteristics and laboratory test methods for retroreflecting road studs intended for use as permanent road marking materials.

This document does not cover non-retroreflective road studs.

Temporary road studs are also covered in a specific annex: Annex E (informative).

It also covers the relevant procedures for assessment and verification of the constancy of performance.

This document describes a test method to determine the friction at 60 km/h after polishing during a fixed number of passes on surfaces of bituminous mixtures samples, or to follow its evolution as a function of the number of polishing passes.

The samples used are either produced in a laboratory or are cores taken from the site.

NOTE This procedure was previously known as Wehner and Schulze method (see [1]).
