Geotextiles In Rural Road Construction
The use of geotextile products in temporary and rural unpaved road construction is one of their most common uses, and work on them is well established. The basis behind their use is that by placing a geotextile between the weak subgrade soil and the aggregate fill the unpaved road construction will be established. The geotextile should have properties:
- To provide a physical barrier to intermixing of the aggregate and subgrade soil
- Provide local reinforcement
- Restrains the subgrade sub-base from downward & lateral movement in rut
- Restrains the subgrade soil from upward and lateral movement b/w the ruts
- Improve the quality of rural roads
- Increase life span of the road
- Cost reduction of repair
- Stands natural climatics like flood /monsoon destruction
