Since our R&D&I Department was created in 1999, we work for the valorization of different by-products considered waste and, especially, for the incorporation of bitumens improved with powder from discarded tires into asphalt mixtures. We have the only Spanish plant capable of mixing bitumen and powder from scrap tires in the asphalt plant itself, protected under the form of "Utility model".
