European standards for surface dressings and slurry surfacings

The European standards for surface dressings (EN 12271 Surface dressing – Requirements) and slurry surfacings (EN 12273 Slurry surfacing – Requirements) have been approved by CEN working group TC227/WG2. One of the prominent features of these standards is that they set performance requirements rather than prescribing “recipes”. For some requirements the standards leave a number of options to the countries themselves.

About "Standardization – Certification – Regulation"

For many years the Belgian Road Research Centre (BRRC) has initiated, or been a major participant in, Belgian mirror groups, European working groups and international pre-normative comparative research with a view to developing or steering new technical specifications and certification by the European Committee for Standardization (CEN) and the International Institute for Standardization (ISO).

Passively safe support structures for road equipment

A little less than 40 % of all road fatalities result from collisions with roadside obstacles. Collisions with such isolated obstacles are about twice as lethal as on average and cause 1.6 times more serious injuries as on average. Natural obstacles (such as trees) are by far the largest group. Additionally, considerable numbers of lives are lost in collisions with lighting columns and other road equipment.
Collisions with lighting columns and other robust support structures account for slightly less than 10 % of the total number of road deaths. Yet for lighting columns and for sign or signal poles there are alternatives that are not inferior in functionality to conventional rigid structures. This makes a major difference for the occupants of a passenger car running into such a support structure.

Geometric inspection of raised traffic calming devices on public highways: road humps

Raised traffic calming devices (road humps) which are meant to reduce the speed of traffic on public highways to a maximum of 30 km/h have to meet the siting conditions and technical specifications laid down in the royal decree of 3rd May 2002, which has amended a previous royal decree of 9th October 1998. The changes introduced by the new decree consist mainly of tolerances in dimensions.

Standards support office (“NAN”)

With support from the Belgian Federal Public Service Economy, SMEs, Middle Classes and Energy, BRRC operates a standards support office that goes by the acronym “NAN”. The object is to inform SMEs in the road branch and make them aware of developments in the field of standardization and, where necessary, to offer them additional support in implementing new standards (which are often mandatory).
