Using innovative materials to reduce road emissions
On 19 November 2015, the DG Environment publication "Science for Environment Policy" published an article concerning a study entitled “Carbon footprint comparison of innovative techniques in the construction and maintenance of road infrastructure in The Netherlands”.
The article indicates that, according to the authors, carbon emissions from Dutch road networks could be reduced by almost a third if more innovative materials and processes were used. In this respect, the potential benefits associated with 10 innovations in road construction and maintenance were assessed and compared to conventional materials and processes. According to the research, the cumulative greenhouse gas reduction potential is 37% for both the main road network and the asphalt roads in the secondary road network, 28% for both bricks and concrete element roads, and 84% for maintenance and control of the total road infrastructure. In terms of concrete, it is noted that reductions can be achieved by reducing the amount of newly made bricks and replacing them with concrete elements, leading to a CO2 reduction of almost 30%. For concrete element roads, the highest reduction potential can be achieved by applying the construction recycling concept called “Kringbouw”.
