About the course

This course discusses the pavement design of roads. All three accepted methods of pavement design are covered including soil factor, R-value thickness and an introduction to MnPAVE for thickness design. Design guide will be used to review the importance of the tools for the following elements of roadway design: data collection and accurate traffic projections; sub-grade soil evaluation and best practices for enhancements; pavement section materials and specifications; and best construction practices and their effect on pavement life.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Discuss pavement design of roads and pavements as well as pavement design procedures
  • Perform exploration and testing on soil
  • Identify soil stabilization, soil characteristics, special sub-grade problems, filtration and drainage
  • Determine recycled pavement materials and implement QA/QC in construction
  • Explain soil behavior and the basic concepts of geotechnical engineering for design of roads and pavements
  • Apply soil stabilization and construction, including how to fix bad soils
  • Enumerate different types of road pavement
  • Examine traffic loads and apply marshal design method on asphalt mixes
  • Identify the tresses in flexible pavement
