The objective is to achieve more environmentally friendly bituminous mixtures through the  implementation  of  strategies  that  allow  the  use  of  polymeric waste as substitutes for virgin aggregates.

The R&D project titled Estrada, led by Extraco, with the participation of Gestan  Conteco, the  support  of  Cetim  (Multisectoral  Research Technological  Center)  and  the  Universidade de  Santiago  de  Compostela (Integrated Group of Civil Engineering and Geomatics of the Lugo Campus), has just passed  the  validation  of  the  DNSH  principle,  which implies the official recognition that it will not cause damage to the environment.

In  fact,  the  initiative  is  not  only  environmentally  friendly,  but  also  aims  to achieve  innovative  circular  economy  solutions,  whose  main  technological challenge focuses on incorporating the maximum content of plastic waste in conventional bitumens to develop hot bituminous mixtures. The DNSH certification is a mandatory requirement for R&D&I projects co-financed by the CDTI (Spanish Center for Technological Development and Innovation) with Next Generation EU funds. It guarantees the fulfillment of six environmental objectives: climate change mitigation, adaptation thereto, the sustainable use and protection of water resources, transition to a circular economy, pollution prevention and control, protection and recovery of biodiversity and ecosystems.
