Pavement System Design

To improve your pavement design techniques, you’ll learn about all aspects of pavement system design, including the testing of soil/base substructure, pavement material mix design, and pavement thickness design. You will also learn improvement methods for existing solids, Hot-Mix Asphalt (HMA) design methods and modification, as well as Portland cement concrete (PCC) material selection. Through detailed examples, you’ll understand how certain materials can optimize the thickness selected for pavement layers based on the most commonly used analysis and design procedures, ultimately giving you the ability to predict their performance. 

This course will benefit engineers, technicians, public works professionals, and contractors who investigate, design, and construct roads and pavements.

• Engineers who manage consultants, design pavements and conduct pavement condition ratings
• Contractors and estimators who design and supply paving materials and equipment
• Paving contractors and their technical staff members
• Facility managers for campuses, developments, and business parks
• Geotechnical and materials engineers
• Project and laboratory managers
• Inspectors and QC/QA personnel
• Engineering managers who decide if and when to implement Mechanistic-Empirical (M-E) design and calibrate M-E models to local conditions
