2025 AACP Airfield Laboratory Technician Course

NEW ALT Course - Instruction days: 10/17 to 10/19 (3.0 days) Exam day: 10/20 (0.5 day)

This course consists of interactive lectures, demonstrations, and hands-on training of fundamental aggregate and asphalt mixture tests used during asphalt mixture production. The course will be split between classroom lectures and hands-on work using the testing equipment in the laboratory. The course will provide engineers, technicians and testing personnel with an understanding of the sampling and testing requirements associated with airfield asphalt mixture production and construction. Approximately 1 1/2 days will be spent in the classroom and 1 1/2 days will be spent in the laboratory. A brief outline of the course follows.
