A highy topical subject in the contribution of road construction to sustainable development is the production of asphalt mixtures at lower temperatures (reduced-temperature asphalt, RTA), because of the advantages from the energy, environmental and engineering points of view. Within a project on European test methods for bituminous mixtures and binders that was initiated by the Belgian Bureau for Standardization (NBN) and aims among other things at improvements with a view to sustainable development, BRRC has undertaken to closely monitor the recent developments and achievements in the field of RTA, both in Belgium and abroad. This includes the following aspects:
This was also a small sequel project to SILVIA, which was funded under the 6th EU Framework Programme. It was carried out by a consortium of BRRC, DRI and FEHRL. The object was to disseminate the knowledge on low-noise pavements gained in the SILVIA project to countries which had not participated in SILVIA. A number of one-day workshops were held in six countries (Slovenia, Romania, Switzerland, Ireland, Portugal, and Greece). In addition, a European working group on the Acoustic classification of road surfaces was formed, which held its first meeting in Ljubljana in April 2008 and its second in Copenhagen in September 2008.
In the years 1999-2001, BRRC actively participated in the research project Recycling and Valorisation of Stainless Steel Slags funded by the European Union under the 4th Framework Programme for SME’s (CRAFT programme).
