Upcoming Class Dates


Continuous Live Chat with experienced Asphalt Institute Engineers will be available throughout online sessions to address questions and comments.


The construction of high quality, long-lasting asphalt pavements begins with their design. Industry experts Tim Murphy, P.E., Murphy Pavement Technology, and Dave Johnson, P.E., Asphalt Institute Senior Regional Engineer, bring their combined 60+ years of experience in this arena to a virtual four-day Idaho Asphalt Mix Design Certification Course. Instruction will begin at 8:30 and end at 4:30, Mountain Time. Morning, afternoon, and lunch breaks will occur. 26 Professional Development Hours are offered to attendees.

Tim and Dave have designed this class to emphasize Idaho specifications for asphalt pavements.

This training provides advanced technicians, designers, and engineers responsible for mix designs with a thorough understanding of the properties of the materials which compose asphalt mixtures, as well as the physical and mathematical processes involved in producing a successful asphalt mixture design. Students will receive training in the entire range of activities related to the design of asphalt mixtures. Successfully passing the online certification test meets the training component requirement for mix design technicians and engineers in the state of Idaho as established by the Idaho Transportation Department.

For detailed, hands-on laboratory training on basic aggregate and asphalt mixture testing for both experienced and inexperienced technicians, we recommend Asphalt Institute’s Basic Mixture Technician Training course.  Unlike this course, it focuses on giving the students a thorough understanding of each test and related processes, while instructing students on the procedures and techniques which will maximize testing accuracy and repeatability.

The specific agenda for the course is as follows:

General Information

  • Start time: 8:30 Mountain Time
  • Lunch Break: 30-minute around noon
  • Ending time: 4:30 Mountain Time
  • One 15-minute break in the morning and afternoon


  • Specifications emphasizing Idaho requirements
  • Aggregates and binder selection
  • Material properties
  • Development of trial blends and batching
  • Volumetric calculations and analysis
  • Superpave mix criteria
  • Mixture performance tests and criteria emphasizing Idaho requirements
  • Use of RAP in asphalt mix designs
  • plus an overview of SMA mixtures

In-class exercises will be assigned. All attendees will receive a Certificate of Attendance from the Asphalt Institute.

Attendees will receive one electronic copy each of the Asphalt Institute’s MS-2, Asphalt Mix Design Methods (a $75 value), and electronic pdf copies of all the presentations.

Who Should Attend

This course has been developed to meet the needs of those actively involved in mixture design, material specifications and field management of asphalt mixtures in the state of Idaho. State and local transportation agencies, consultants and contractors who are involved in asphalt materials and mix design will benefit from this course.
