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 project originated from the search for an alternative to conventional porous asphalt, which, while retaining the many advantages (acoustical properties, drainability, skid resistance, resistance to rutting) of this type of mixture, was required to reduce or limit its disadvantages (winter behaviour and durability).
