The design of a new pavement or an overlay of an existing pavement must account for the subgrade conditions, traffic volume, traffic loading, and environmental conditions. With asphalt overlays, the condition of the existing pavement must be known. To learn the processes and techniques of pavement design, this class will cover the input parameters for design and considerations for overlaying an existing pavement.

To aid in the facilitating of pavement designs, the PaveXpress application (www.pavexpress.com) will be utilized in class. PaveXpress integrates all the considerations for pavement design in an easy-to-use stepwise process following AASHTO and other nationally recognized design procedures. Laptops are required for this course.

The outcomes of this class should allow the attendee to:

  • Learn the key factors that must be evaluated for a proper new or overlay pavement design.
  • Learn to use PaveXpress for designing pavements.
  • Perform basic pavement designs and understand the economic consequences of over- or under-designing a pavement.
