highway engineering in mountainous terrain

Mountain roads are typically associated with difficult ground access, numerous slope instability problems and shortages of good construction material. These conditions require carefully designed off-site drainage, erosion protection measures and identification of the best locally available materials.

As a result, design and construction of roads in this terrain requires special expertise in relation to:

  • geological and geotechnical factors
  • route alignment
  • geometric design
  • design of slope protection and stabilisation measures

Geotechnical considerations typically have a great influence on highway engineering in mountainous terrain since they can significantly affect the cost of constructing and maintaining roads in this difficult environment.
