| Application: ROAD CONSTRUCTION |
|
|
|
|
|
|
General |
|
|
|
The successful of road structures over saturated soft soils begins with the stabilization of the underlying soft subgrade.
|
|
Problem |
|
|
|
Subgrade support problems are most prevalent over wet, saturated, fine grained soils with a high sensitivity to remoulding. The major cause of failure is poor drainage and loss of support, due to contamination of the aggregate base materials by the underlying soft subgrade soil during construction.
|
|
|
|
|
|
|
Solution |
|
|
|
To prevent contamination, Geotextile can be placed between the aggregate base course and the subgrade to act as a separator, thus maintaining the designed aggregate thickness of the roadway.
|
|
 |
 |
| Separation function of Geotextile prevents intermixing of good aggregates and poor subgrade |
Loss of good aggregate into poor subgrade during construction |
|
|
|
Geotextile performance benefits |
|
|
- Allows more open-graded aggregate to be considered in the design to further enhance drainage
- Reduces the excavation depth of unsuitable subgrade
- Reduces aggregate thickness required to stabilize the subgrade
- Maintains a more uniform settlement of the subgrade especially in transition areas
- Improve subgrade strength and extend the life of the system
