Processed Coarse Aggregate as Base Course in

The study aimed to utilize the waste crushed concrete pavement as recycled or processed coarse aggregate for base course in concrete roads. Specifically, it aimed to determine the physical properties of the processed aggregate derived from waste crushed concrete pavement in terms of gradation, abrasion loss, Atterberg’s Limits, Compaction test, California Bearing Ratio and Field Density Test.

Aggregates - Types of Aggregates | Coarse

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)
