This virtual Mix Design Technology Certification (MDT) course 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 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 MDT 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
