Using raw materials and energy economically helps to achieve sustainable road construction. As an alternative to consuming primary raw materials – which are mostly not renewable and, therefore, limited in supply and availability – secondary raw materials can be employed. These are materials used previously in an infrastructure or in some industrial process or product, which are considered as wastes when reaching the end of their service lives.
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).
The objective of this three-year research project, in which thirteen partners were involved, was to develop techniques to treat steel slag (both LD and EAF) right from the production stage so as to give it good characteristics and volume stability. It was completed in the year 2000 and the final report has been released.
The main objective of this four-year European research project (from 1st January 2009 through 31st December 2012; fifteen partners) conducted under FP7 was to maximize the reuse of reclaimed asphalt (RA) in bituminous mixtures, with as little downscaling of the material and as little use of new material as possible.
