Nineteen construction professionals from Ohio, Michigan and Indiana attended an aggregate technician certification training program held at Gilson Company in Lewis Center, Ohio. The attendees represented construction businesses working in asphalt, concrete, aggregates, soils and paving. The group participated in the Ohio Aggregates & Industrial Minerals Association (OAIMA) Ohio Level II Aggregate Technician Training on March 20 and 21. This was the first OAIMA certification training program held at Gilson for 2019; generally three are held each year.
On the morning of the first day, attendees took classroom training, and a written examination in the afternoon. On day two, participants performed various procedures through hands-on activities held in Gilson’s Application Center. The attendees rotated through different stations which included Crush Count, #200 Wash, Sieve Analysis of Coarse Aggregates, Sieve Analysis of Fine Aggregates and Relative Density/Unit Weight.
The aggregate training, testing and certification program is the same that is required by the Ohio Department of Transportation of its technicians. The OAIMA is a trade association that represents all the mining operations, except coal, in Ohio.
