Building lasting infrastructure

Save our resources by reducing our consumption of materials and energy, limit pollution… Eurovia is committed to building and upgrade infrastructure through increasingly environmentally friendly technologies in response to the increasingly stringent requirements of local residents, users, and clients who demand sustainable development solutions. That is why the Company provides custom solutions that favour recycling and minimize nuisances.

Recyclovia® or taking recycling “on the road”

The need to reduce natural resource consumption, the sometimes vast distances between plants and worksites, and the increasing stringency of landfill use regulations are all factors that favour road-maintenance techniques that use minimal amounts of new aggregate.

Accordingly, Eurovia has developed Recyclovia®, an on-site reprocessing method for the surface layer of flexible and semi-rigid road pavements and structural reinforcement of up to 15 cm.

Recyclovia® is the result of experience acquired by Probisa (a Eurovia subsidiary in Spain) since 1998 and is implemented through a unique and compact unit.

NOxer® uses light to eliminate polluting gases

Road pollution remains a serious problem in confined areas or in proximity to major thoroughfares. In an effort to reduce road pollution and help to preserve the environment, Eurovia teams have developed NOxer®. This paving solution uses photocatalysis to cut down gas emissions by 10 to 40%. Residue is evacuated by rainwater in concentrations well below allowable thresholds in mineral water. NOxer® requires no maintenance and always remains effective....

NOxer® can be applied to noise-attenuation barriers - as in Paris, Manchester or Lannion - walls at car parks, tunnels, surface pavement (high-traffic roads, conventional city streets, and fast food drive-throughs). To date, Eurovia teams have implemented NOxer® on more than 45,000 m² of road surfaces, including recently at theA86 toll areas, in Paris, and in Madrid.

Viasphalt®BT: environmentally friendly low-temperature asphalt

Poured asphalt coatings consume a great deal of energy as a result of its high production temperature, which is close to 240°C. The negative environmental impact of asphalt production is due to the heating of the mix ingredients and the time required for mixing, which generate large volumes of greenhouse gas emissions....

In efforts to reduce air pollution and related nuisances, Eurovia's research centre has developed low-temperature Viasphalt BT, a process that yields a 60°C to 80°C drop in production temperature depending on the type of asphalt as well as more comfortable paving conditions. The process results in major energy savings and virtually eliminates vapour emissions.

This process received a Special Sustainable Development Prize in the Processes and Technique category.

GAÏA.BE®: the eco-gauging tool

Gaïa.BE®, which was developed by researchers and operations personnel using product lifecycle analysis, models the environmental impact of each phase in the implementation of worksites, including all the stages of roadwork, quarry extraction, and road surface compaction.

It provides results that take local characteristics and constraints into consideration.

Relevant criteria are selected from the worksite's environmental profile included in Gaïa.BE's environmental indicators: natural resource and energy consumption, polluting emissions, waste production, and preserving the quality of life of residents. Its reference system was established using recognized and public data produced by the roadwork industry in line with current international standards. With this tool, Eurovia promotes environmentally friendly solutions that contribute to the preservation of natural resources, help mitigate climate change, and protect people.

Germany: high recycling rates

In 20 years, the proportion of re-used pavement employed in new road construction or repair has doubled to 80%. As a result, annual bitumen consumption has dropped by over 7,000 tonnes.
