Nordic certification of road marking materials in Norway and Sweden 2016–2018

Trond Cato Johansen

A Nordic certification system for road marking materials, that applies to the countries of Denmark, Norway and Sweden, was introduced in 2015. In these countries, a documented product approval is required in order to use a road marking material on roads managed by the national road authorities. Product approval is based on monitored and documented performance measurements of material samples applied on test fields on public roads.

A Norwegian-Swedish test site was established in 2015, where between 43 and 81 materials have been applied yearly. The applied materials are followed up with performance measurements for two years. The materials are approved (certified) in relation to the number of wheel passages they will stand.

The certification system includes road marking materials for longitudinal road markings in categories with respect to colour (white, yellow), type (type I, type II, antiskid) and thickness (0.4, 0.6, 1.5, 3 and 4 mm).

The present report documents the follow-up performance measurements that were carried out at the Norwegian-Swedish test site in 2018, i.e. one-year follow-up measurements for materials applied in 2017 and two years follow-up measurements for materials applied in 2016. The performance parameters include the coefficient of retroreflected luminance (RL) under dry and wet conditions, the luminance coefficient under diffuse illumination (Qd), the friction, the chromaticity in daylight, and the chromaticity of retroreflected light (yellow materials, only).
