The royal decrees of 9th October 1998 and 3rd May 2002 on road humps lay down the requirements and technical specifications to be met by these devices. BRRC has developed for the geometric inspection of “raised traffic calming devices on public highways”, as they are officially named, a method of measurement which allows rapid assessment of their compliance with requirements and specifications.
The law authorizes traffic calming devices with varying geometries and dimensions, but requires that they should be adapted to local circumstances (location, types of vehicle in traffic). As a result, not all specified devices (and, all the more so, those failing to comply with regulations) have the same intrinsic effectiveness in reducing speeds. That is why the choice of a traffic calming device with any ensuing layouts or facilities requires careful reflection on the objectives to be met. To collect objective input for this reflection, the Centre also makes measurements on existing sites, where both geometric data and travel speeds are recorded.
To advance the quality of asphalt and to design durable asphalt mixtures, it is necessary to have good test methods for the evaluation of bitumen and asphalt properties both in the laboratory and on site. The link between the test results and long-term performance is of major importance in this respect. Moreover, uniformity in the test methods is pursued at the European level.
L’objectif de ce projet de deux ans (1/10/2012 – 30/9/2014), subsidié par le NBN, était de continuer à développer et à améliorer les méthodes d’essai européennes qui tombent dans le domaine de travail des comités de normalisation européens CEN TC227/WG1 (pour mélanges bitumineux) et CEN TC336/WG1 (pour liants).
Construction Products Regulation (CPR) (EU) No 305/2011 has been fully applicable since 1st July 2013. It has definitively replaced Construction Products Directive (CPD) 89/106/EEC. With this new regulation the European Commission (EC) intends to clear up a number of persistent misunderstandings arising mainly from confusion with other directives which also underlie CE marking.
