Q: What is the application of geotechnical engineering in highway pavement design ?
  • A. Designing the thickness of flexible pavements
  • B. Determination of traffic load
  • C. Designing of the footing for rigid pavements
  • D. Analysis of stability of the camber slope
Correct Answer: Option A - Geotechnical engineers are generally responsible for determining the thickness of flexible pavement needed for a 20 years structural design life based on traffic loading, soil conditions and local climate and jurisdictional factors.
