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:

In this project several variants were developed, some of which were based on the French EME (“enrobé à module élevé”). After extensive testing in the laboratory ten variants were laid in 2006 on a heavily trafficked section of the E19 between Brussels and Antwerp. This was followed by the drafting of recommendations and performance specifications for this type of asphalt mixture, in cooperation with the Flemish department of mobility and public works (MOW). All information on this project can be found in a research report (CR43/07) published by BRRC.
