Instructor:  Christopher Senseney, Ph.D., P.E.

Course Length: 1.5 Hours

Purpose and Background

Although newer mechanistic-empirical design methodologies have been developed, namely AASHTOWare Pavement ME, most state highway agencies still use the empirical-based AASHTO 1993 pavement design methodology procedures to design their roadways. Furthermore, most municipal agencies in the U.S. specify AASHTO 1993 for arterial and collector roadway pavement design. The purpose of this course is to describe, in detail, each AASHTO 1993 design input parameter for both flexible (i.e. asphalt) and rigid (i.e. concrete) pavement. At the end of this course, students will be able to design a flexible or rigid pavement using AASHTO 1993 procedures.

Learning Outcomes and Benefits

Upon completion of this course, you will be able to:

• Explain and select design input parameters for the AASHTO 1993 asphalt design procedure
• Determine an asphalt pavement structure given design inputs
• Determine an effective roadbed (subgrade) resilient modulus for asphalt pavement design based on the relative (seasonal) damage concept
• Explain and select design input parameters for the AASHTO 1993 concrete design procedure
• Determine a slab thickness given concrete design inputs
• Be proficient at AASHTO 1993 pavement design procedures
• Explain the meaning behind each AASHTO 1993 design input
• Optimize pavement designs for certain applications

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
