Since July 15, Eurovia Bretagne – Rennes has built the pavement for the Lohéac (35) detour on behalf of the Ille-et-Vilaine Departmental Board.
This initial phase of the work includes crushed stone and bonding mixtures of the current section (3 km) of the RD 177 (Rennes/Redon axis).
In order to optimize the agency’s resources, the two mixture teams as well as the Emeraude Enrobés mixture plant, located in Vignoc, were set up at two work stations.
Two thousand, six hundred tonnes of mixtures were produced and spread every day (20,000 t in eight days).
The environmental aspect of this site is important: since the recycling rate of the mixtures is 25%, the Tempera®
procedure (warm mix ranges) applied to build them at 135° saves energy and reduces greenhouse gas emissions by 20%.
The second phase involves building the ramps and laying the wearing cover using Rugovia®
(gap-graded asphalt concrete) and will take place in September.
