NOVAFOR and MEGAROUL : doubling up at Colas
As part of a bid involving the access road to the Chazan Wood Energy facility in Chamboeuf, Colas Nord-Est Côte d’Or Agency proposed a technical alternative with cold in place recycling for the road base using Novafor and a wearing course in Megaroul.
Approved by the Engineering Consultancy (BEREST) and selected by the Owner (town of Chamboeuf), the technical alternative included:
- Cold in place using hydraulic road binder (15,000 m²)
- Wearing course in 0/20 mm Megaroul (2,800 t.).
The existing pavement was recycled to a depth of 40 cm using the Novafor process, with additional 0/20 mm road base asphalt when required on certain sections. The hydraulic road binder content was 4 %.
The 0/20 mm Megaroul was manufactured by Dijon Enrobés (hot mix plant) and applied in an 8 cm thick course, directly on top of the recycled pavement.
