REMSA Innovation Theater: Substructure Investigation and Tie Testing Methodology from Sol Solution
The presentation from Sol Solution’s Fabien Ranvier and Younes Haddani covered methodologies to “assess ballast condition thanks to geophysical/geotechnical tests as well as tie characterization with nondestructive methods.” The presentation was divided into two different sections: Innovative Substructure Investigation and Innovative Tie Testing Methodology, which utilizes a nondestructive geophysical method based on the analysis of mechanical waves.
In investigating the ballast, a Pandascope takes photos within the substructure and can identify wet spots, ballast pockets, and mud pumping areas. Additionally, they can figure out how much ballast can be reused after undercutting and how much new ballast is needed. Reusing what ballast they can saves money. As well, based on the information and data gathered, advice can be given to railroads on the condition of their lines. The benefits include:
- Adaptability to line constraints: There’s easy implementation when traffic ban is on.
- Cost-Effectiveness: Equipment is light and can fit into a backpack. The test is quick to complete, and it allows for access on and off the track.
- Reliability: More than 100,000 Pandoscope tests have been done around the world.
