FOR MATERIALS TESTING TECHNICIANS Aggregate Qualification is designed for those individuals responsible for field sampling and testing of aggregate for bases, bituminous mixes, or Portland cement concrete. Participants include contractor and supplier quality control personnel, consulting engineering and materials testing firm personnel, quality assurance technicians, and public agency personnel. The Process for Qualifying in Aggregate: Meet the prerequisites. (see below) Pass the written and performance examinations. Course Length: approximately 5 days Course Size: 12-15 recommended Prerequisites for being Qualified in Aggregate: None Recommendation: The participant should exhibit basic mathematics and reading comprehension skills.
