What is it about?
Eiffage Route company has developed an innovative road material called Biophalt®. It comprises a plant-based binder, made with wastes of paper production, and a high amount of reclaimed asphalt, coming from the recycling of old pavements. It is produced at a lower temperature compared with conventional asphalt mixes and is suitable with any type of traffic and roads, including highways. In this paper, both mechanical and environmental performances of Biophalt® are presented. Laboratory tests results show that its mechanical behavior is comparable with the one of a conventional asphalt mix, while its CO2 balance is far better, as confirmed by a Life Cycle Analysis (LCA).

Why is it important?
The lowering of mixing temperature and the use of recycled materials contributes to reduce the environmental impact of Biophalt®. Furthermore, thanks to the vegetal origins or its binder, emissions of greenhouse gases that occur during the mixing, the transportation and the laying down of Biophalt® are compensated. Thus, it allows reaching the carbon neutrality for the whole steps of a jobsite.
