A LOW-CARBON ASPHALT PLANT
Eurovia’s (VINCI Construction) asphalt mixing plant at Sainte-Suzanne-et-Chammes, in western France, was completely modernised and equipped with its own solar power plant in 2020. It uses the latest technology to reduce its carbon footprint: energy is saved by drying materials in hangars, more efficient latest generation worksite machines are used, natural gas instead of heavy fuel oil, electrically heated alsphalt binder tanks, and more asphalt aggregate (up to 50% instead of 30% in the old plant). As a result it has cut its asphalt production CO2 emissions by 40%.

POWER ROAD®, A ROAD THAT CAPTURES, STORES AND REDISTRIBUTES ENERGY
Power Road® works like a heat exchanger. Throughout the year, and especially in the summer, the road captures the sun’s heat energy. It is either transferred to nearby buildings and infrastructure (e.g. to heat swimming pools or provide hot water for office buildings), or stored in geothermal wells for reuse in the winter to heat buildings or remove snow and ice from roads, thus avoiding the need for huge quantities of salt.
