Offered in partnership with the University of Arkansas College of Engineering, the goal of this course is to provide a broad, foundational understanding of asphalt emulsions. This course takes approximately 16 hours to complete and registrants will have 4 weeks to complete the class. Upon completion, if requested, 15 professional development hours will be awarded.

After a brief overview of the history and importance of asphalt emulsion, tools will be provided to understand the classification of asphalt emulsion into cationic versus anionic, rapid versus medium versus quick versus slow setting, and how the type of asphalt emulsion influences breaking and curing. Additionally, a broad perspective of the production of asphalt emulsion will be provided, followed by an overview of existing AASHTO specifications for the testing, sampling, and handling properties of asphalt emulsion, the classification of asphalt emulsion, tests on the recovered asphalt emulsion residue, and performance tests developed for asphalt emulsion pavement maintenance and rehabilitation products. Finally, uses of asphalt emulsion in roadways will be covered, including spray applications and mixture applications, encompassing an introduction to all pavement maintenance and rehabilitation products.

Learning Objectives
Classify asphalt emulsion by physical and chemical characteristics
