Case 2 Foundation stabilization
LCA Studies
The use of Geosynthetics leads to lower impact concerning all indicators investigated compared to a
conventional road:
-
~ 11% (or 800 tons) saving in CO 2 -equivalent per 10 km of road (12 m width).
-
~ 5% reduction in the non-renewable cumulative energy demand.
-
Note: As compared to lime / cement stabilization, a geosynthetic solution saves 30% in CO 2 equivalent.
This study shows
​The use of geosynthetics leads to:
-
lower environmental impacts concerning all indicators investigated compared to a conventional road
-
lower climate change impacts compared to lime or cement stabilisation
-
~11% (or 800 tons) saving in CO2 per 10km of road ≈ 3,200,000 km in a car (80 trips around the world) • Vs lime/cement stabilisation save 30% ≈ 12,000,000 km
