This test method describes how the defects in a surface dressing can be visually assessed. These defects include fatting up, tracking, bleeding, scabbing, tearing, fretting, and streaking (more information on these various forms of distress can be found in BRRC’s code of good practice R71/01 “Code de bonne pratique pour les enduits superficiels”).
Damage can be assessed in two ways: qualitatively and quantitatively.
A qualitative method will assess the rate of damage by simple rules. The quantitative method will measure the defects in much more detail.
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).
BRRC has been monitoring the growing interest in road safety audits and inspections for a number of years. As early as in 2002, the Centre participated in the activities of the European Road Federation (ERF).
On 29th November 2008, directive 2008/96/EG of the European Parliament and the Council of 19th November 2008 on road infrastructure safety management was published in the Official Journal of the European Union.
The publication of the European Construction Product Directive in 1989 marked the beginning of the gradual introduction of European standardization. European standards are to replace existing Belgian standards, or at least require them to be thoroughly revised. By affixing a CE mark, the manufacturer declares that the performance characteristics of his product have been determined by the appropriate European standard and that measures have been taken for the product to continue meeting these declared characteristics.
As the actors in the road equipment branch were concerned about the impact of this European standardization, a steering committee on European standardization in the road equipment branch was formed at BRRC in the spring of 2003. The first task of this committee was to increase the awareness of, and disseminate information to, the various actors in the field: road authorities, manufacturers, specialized institutions, etc. For that purpose, a series of thematic sessions on the standardization and CE marking of road equipment was held in March 2004.
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.
