  • Chapter 3 Aggregate Sampling, Testing, and Quality

    For coarse aggregates used in concrete applications, Kansas DOT also requires addi- tional tests for durability (KTMR-22) and wetting and drying (KTMR-23) (Kansas DOT 2017). Alaska DOT runs its own test method (ATM 306) for determining the percentage of flat and elongated particles in coarse aggregate (Alaska DOT 2016).Aggregates Types of Aggregates Coarse Aggregate, Fine,Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)
