4.6 Designing low-volume roads
This presentation covers building low volume roads – roads carrying less than 200 vehicles per day and less that about 1 million equivalent standard axles over its design life. It was delivered at the 5th Africa Transportation Technology Transfer (Tē) Conference for the Africa Community Access Programme workshop on rural accessibility and mobility.
The presentation includes:
- Engineered earth roads
- Gravel roads
- Low-volume sealed roads
- A performance review of Malawi's lowvolume sealed roads
- The dynamic cone penetrometer method of pavement design.
Engineering a low-volume road requires imagination and innovation while working with nature and locally sourced materials. Projects should also maximise the involvement of local communities and contractors. The presentation suggests using in situ structures as much as possible when dealing with existing gravel roads. These have generally been well compacted by traffic and should not be disturbed unnecessarily.
