‘World’s first’ low-carbon roadworks project using 100% electric equipment
06 October 2023
Vinci Construction and Fayat have carried out what they say is a ‘world’s first’, a low-carbon roadworks project using 100% electric equipment as part of the works to resurface Rue du Lieutenant-Petit-Le-Roy in Chevilly-Larue, France.
The project was carried out by Emulithe (a Vinci Construction subsidiary) and involved making the street one-way and creating a cycle path.
Following two days of training, Emulithe’s teams successfully used – as part of a trial – a 100% electric, rechargeable and silent sprayer, paver and roller, reducing greenhouse gas emissions and noise pollution compared with those produced by conventional worksite equipment.
This is said to be the first time that all-electric models of these three roadworks machines had been used on a single worksite. This full-scale trial owes its success to the collaboration with the Fayat Group, manufacturer of the electric sprayer, paver and roller used on this worksite.
The worksite provided an opportunity to test the performance of these new electric machines – identical to their combustion-engined equivalents – and how long their batteries would last during a day’s work. It also confirmed the significant reduction in CO2 emissions, with this low-carbon worksite saving 0.25 tonnes of CO2 per day compared with a worksite using conventional machines.
Vinci Construction has a target of reducing CO2 emissions by 40% by 2030. To help meet this goal it says its use of electric-powered vehicles, light equipment, excavators and even lorries on worksites is growing.
What all-electric equipment was used on the site?
The Box, from Secmair, a sprayer designed with decarbonisation in mind. It is said to boast excellent range and insulation, great usability and simple operation.
The SD1800W e is the first mass-produced electric urban paver, manufactured exclusively by Dynapac. Its 98-kWh battery provides long range and fast recharging. Its low noise level, zero fine-particle emissions and zero smoke emissions mean it has a much lower carbon footprint.
The Bomag BW 100 ADe-5 electric roller is rechargeable and equipped with a battery, motor and inverter technology. Its operation it silent and, says Fayat, its simple information display on the dashboard provides excellent visibility.
