L800-L810 Nîmes (30)
Client : M ABERLENC
Project manager : M. ORTEGA
Company : SNCF
As part of the renewal of an old track around Nîmes (line 800 000 and line 810 000), the SNCF commissioned us to determine the granulometry of the ballast layer (ballast + fine particles).
During this study, analyses were carried out on two types of samples :
- Fully recycled ballast : a sample comprising only old ballast, which is screened and then returned to the track
- Partially recycled ballast : sample comprising a mixture of old, re-sifted ballast and new ballast
Over the course of the 11-week operation, 69 samples were taken along more than 25 kilometres of the two lines combined.
