The GREENROAD project was born to demonstrate a technically feasible alternative to conventional mixtures and to improve the sustainability of the road sector. The project involves the development of Asphalt Concrete mixture manufactured with steel slag of Electric Arc Furnace, which is produced in the region and currently implies a high environmental cost; RAP from other mixtures; and bitumen modified with end-of-life tyres. Besides, a wax has been used to decrease the manufacture temperature and improve the environmental impact. Finally, a mixture with more than 80% of recycled aggregates and with a decrease of temperature from 20°K to 30°K was achieved in laboratory, reaching the requirements for the maximum category of heavy traffic level (T00) of the Spanish specifications.
