29 Jun First validation of the SustainEuroRoad software in the regional road 1089 in France
The department of Gironde (France) was the first where a specific road technique adapted to climate change was deployed within the SustainEuroRoad project. The jobsite was concretely located in the departmental road 1089 and operations were completed by using cold in-place recycling with bitumen emulsion which means:
- Plane 8 to 10 cms of the road (bituminous materials)
- Mix the aggregates with some emulsion of asphalt, some water and a little cement
- Put back in place the new bituminous mix and roll it
The SustainEuroRoad consortium monitored materials, machine and asphalt plant consumptions during the works. Experts also worked on an environmental comparison with the software SEVE -TP between:
- The alternative technique (cold in-place recycling with bitumen emulsion), and,
- The basic technique: planning the road and applying a new hot mix asphalt (gravel bitumen)
While both techniques had the same technical performance, the comparison revealed a strong environmental gain in favor of the cold in-place recycling with bitumen emulsion reducing:
- 75 % of GHG emissions
- 73 % of energy consumption
- 90 % of natural aggregates
A complete descriptive article will be published in September detailing performance for both basic and alternative solution being the latter more adapted to climate change and respecting Green Public Procurement principles.
