Roelofs starts on ‘world’s first’ bio-asphalt road
By Leila Steed04 June 2021
Engineering contractor Roelofs has started work a road section made of a bio-asphalt with a plant-based lignin binding agent, which is said to offer a “significant CO2 reduction” in road building.
The 250-metre-long stretch of road is being constructed in the north of the Netherlands, on the N987 between Siddeburen and Wagenborgen.
The top layer of asphalt will incorporate a new Dutch lignin product developed by Avantium – a specialist in the field of renewable chemistry.
Around 1,000kg of Avantium’s Dutch lignin will be used as a substitute for the bitumen liquid binder traditionally used in asphalt.
Gerard Hoiting, managing director at Roelofs, said, “As a company we have the ambition to be climate neutral in 2030. Not only internally, but also with clients and partners we look for innovations and concrete applications and inspire each other towards a better world. This collaboration is a great example of this.”..Sign in to continue reading.
