INSTRUCTOR: Christopher Senseney, Ph.D., P.E.
Course Length: 90 minutes
Webinar Brief
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.
Benefits and Learning Outcomes
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
Achievement of the learning outcomes by attendees will be assessed through a short post-assessment (true-false, multiple choice and fill in the blank questions).
