Reinforcements of non paved roads
Reinforcement of unpaved roads.
Operation
More than one utility: The improvement provided by the StrataBase and StrataWeb boosters is attributed to three key mechanisms:
-
Lateral constraint of displacements: primary mechanism of reinforcement that can be translated as a lateral constraint of the base/sub-base aggregate (ballast/sub-ballast) when it is subjected to surface loads.
-
Improved load capacity: as StrataBase and StrataWeb are materials with high tensile strength, they promote greater soil mobilization, generating greater support capacity in addition to reducing the stress on the subgrade.
-
Membrane Effect: When requested, StrataBase and StrataWeb assume a tensioned membrane shape that provides a reaction to the stress supporting the imposed load.
Characteristic
Reinforcement of Roads
- Easy application.
- Ideal for mining and agribusiness service roads.
- Reinforcement installed in the subgrade contact to optimize the application.
- Several calculation methods available in the bibliography, with emphasis on Giroud and Han (2004).
- Rigid geogrids perform better than woven and geotextiles.
- Geogrid joint strength and stiffness are the most important parameters.
