Description

Sustainable design of pavements for roads, mining, airports, industrial warehousing and freight terminals is important for safety, serviceability and structural adequacy. It affects the other phases of the ‘pavement’ life cycle including construction, operation and renewal and maintenance. This workshop outlines 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 tools for the following elements of roadway design such as data collection and accurate traffic projections, subgrade 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:

  • Determine the principles of pavement design and geological data-site investigation
  • Enumerate the characteristics of soil
  • Recognize the materials used in road construction
  • Discuss the introduction to MnPAVE for thickness design
  • Identify types of road pavement, layers, traffic loads and structural design
  • Use the pavement deign codes and proper procedures in road pavements design as well as AASHTO methods
  • Implement road testing in accordance to AASHO and WASHO standards
  • Apply subgrade soil evaluation and best construction practices
  • Explain the overview of subgrade soil enhancement practices
  • Discuss pavement section materials and best construction practices
