Goals and Objectives

The purpose of this 4.5 day workshop is to provide engineers, testing personnel, and inspectors a basic understanding of the asphalt mix design process. This will be accomplished through a review of materials specifications, test procedures, and general mix design requirements for a Superpave or Marshall volumetric mix design and will include hands-on training using standard test procedures and specification criteria. Upon completion, attendees will be able to develop a volumetric mix design in their laboratories. The primary focus of the course will be on the Superpave mix design system. This course includes NCAT certification or mix designer certification for the Georgia Department of Transportation.

Program Content

This course consists of intensive lectures, demonstrations, and hands-on training using Superpave and Marshall design methods and volumetric mix design procedures. The course will be split between classroom lectures and hands-on work in the laboratory. Approximately 2 1/2 days will be spent in the classroom and two days in the laboratory. A brief outline of the course follows.

Lecture:

  • - Overview of asphalt mix design methods
  • - Superpave binder testing and specification
  • - Testing and requirements for aggregate properties
  • - Volumetric analysis
  • - Superpave mix design
  • - Moisture susceptibility testing
  • - Other laboratory performance tests for rutting and cracking resistance

Laboratory:

  • - Demonstration of binder testing procedures
  • - Aggregate tests associated with Superpave
  • - Volumetric mix design using the Superpave gyratory compactor
  • - Moisture susceptibility testing
  • - Rut testing with Asphalt Pavement Analyzer and Hamburg Wheel Tracker

Exam and Certification

An exam will be given on the last day of class. Participant must score 75% or better to receive certification.

Materials

Each participant will be provided a workbook and a copy of the Asphalt Institute's "Asphalt Mix Design Methods" (MS-2) manual.

Fees, Refunds, & Deadline

The registration fee of $1400 includes the training program, course materials, and breaks. Costs for housing, food and transportation are the responsibility of each participant. Registration fees must be paid at time of registration. Registration closes 2 weeks prior to start date of course or when class is full, whichever comes first. Cancellations received at least 2 weeks prior to the course start date will result in a full refund. No refunds will be provided for course cancellations after that date; however, substitutions will be accepted.

Eligibility

NCAT will accept applications from any individual who would like more information about asphalt mix design procedures. To get the most out of the course, it is recommended (but not mandatory) that the attendee have some experience with mix design procedures.

Continuing Education

The course will provide 36 Professional Development Hours.

Location

This course will be conducted at NCAT's research facility at 277 Technology Parkway in Auburn, Alabama. Hotel accommodations are close by.
