SolarRoad units installed in cycle path in Estampes

French road building contractor Charier has introduced the SolarRoad kit (SRK) on a newly laid cycle path in Etampes, France. Two SRK units convert sunlight to electricity and provide lighting for a roundabout near Etampes, a small commune of around 26,000 people about 50km south-west of Paris. The installation helps Charier meet sustainability objectives within the framework of the Paris Agreement. An SRK has four elements of 2.5m x 3.5m and delivers around 3,500kWh per year, which according to Solar R

Two SRK units convert sunlight to electricity and provide lighting for a roundabout near Etampes, a small commune of around 26,000 people about 50km south-west of Paris. The installation helps Charier meet sustainability objectives within the framework of the Paris Agreement.

An SRK has four elements of 2.5m x 3.5m and delivers around 3,500kWh per year, which according to 8663 SolaRoad is enough energy to power an average household for one year.

The solar panels can be driven upon but also carry cables. They contain LED lights to create lines and signage without paint and heating elements to prevent snow and ice accumulation. Microprocessors let the panels communicate with each other, a central control station, and vehicles. The glass has a tractioned surface which is equivalent to asphalt.

The technology can be applied to a business park, courtyard, square, bike path or a footpath. It can provide energy for lighting, illuminating a shop window, heating, Wi-Fi access points or - as now in Groningen, the Netherlands - a charging point for e-bikes and mobile phones.

    An ambitious objective has led to significant steps in the reuse of PA (porous asphalt). While the market incidentally produces PA with a maximum of 30% of recovered raw materials, BAM has introduced its own innovations, enabling more than 90% of raw materials to be reused. And this year, subsidies from the European Commission will enable the LE2AP demonstration project to be constructed: one kilometre of sustainable PA. Large-scale production is also being developed.

    Statistics show that wet weather and the dark is not the best mix for driving, but road markings offer a safety solution While good road markings are essential any time of the day, it is perhaps at night when roads are wet that they can offer extra guidance. Statistics are said to reveal that an estimated 50% of all accidents happen during the night when it rains but such conditions occur only 10% of the time and when there are usually less vehicles on the road. Indeed, at the 1st Road Marking Symposium hel
