The Mix Design Technology Certification (MDTC) course provides advanced technicians, designers, and engineers responsible for mix designs with a thorough understanding of the properties of the materials that compose asphalt mixtures, as well as the physical and mathematical processes involved in producing a successful asphalt mixture design. Students will receive training over the entire range of activities related to the design of asphalt mixtures: aggregate and binder selection, material properties, development of trial blends, batching, volumetric calculations and analysis, Superpave mix criteria, mix performance tests and criteria, use of RAP in asphalt mix designs, plus an overview of SMA and open-graded mixtures.

This MDTC course focuses on how advanced technicians, designers, and/or engineers use laboratory and project information in the mix design process to create long-lasting asphalt mixtures, supplemented with videos on tests and laboratory processes involved in asphalt mix design.

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 (BMT) Training course. Unlike MDTC, this course focuses on giving the students a thorough understanding of each test and related processes, while instructing students on the procedures and techniques that will maximize testing accuracy and repeatability.

Optional Certification Testing

For MDTC course offerings held virtually, the optional written exam will be scheduled and proctored virtually. Virtual proctoring includes the use of a webcam which allows for the same level of supervision as in-person proctoring. The exam is designed to be challenging enough to allow only those students who have a good understanding of the design process to pass. A passing score is 80% or higher. Students passing the optional written certification exam will earn the Asphalt Institute’s Mix Design Technology Certification.

Several specifying agencies have accepted the Asphalt Institute Mix Design Technology Certification, either in whole or in part, as meeting the requirements for certification for their agency. Prospective participants should verify the applicability of this certification with their local agency.

Recertification

While Asphalt Institute’s MDTC does not have an expiration date, Asphalt Institute is now offering an MDTC renewal option. MDTC certificate holders needing to renew their certification should inquire by emailing seminars@asphaltinstitute.org. Current certificate holders will be verified prior to recertification registration.
