If circumstancesGradation Test - Pavement Interactive1. Obtain an aggregate sample of adequate mass from one of the following locations: aggregate stockpiles, bins, dump trucks, conveyor belt, or the roadway. 2. Mix and reduce the sample (Figure 6) to an amount suitable for testing. This process of reducing a sample size is often referred to as "splitting" the sample (Video 1).Homogenization process of field samples of recycled aggregatesA homogenization process of recycled aggregate is analyzed. • The uniformity of the recycled aggregate is compared with reference methods. • The evolutions of the water absorption, granular composition and size are evaluated. • Recommendations could be deduced for a method to homogenize the field sample.Procedures for Aggregate Inspection aggregate testing for state or federally funded projects require Michigan Certified Aggregate Technician (MCAT) training at the level appropriate for the acceptance work.
