Table-4 Grain size parameters From the test data it is observed that increase in the percentage of crusher dust decreases C u and C c values i.e. C u values from 11.04 to 4.04 and C c values from 2.72 to 0.75 respectively. At higher percentage of crusher dust with respect to aggregate a wider variation in range of particles were observed these may lead to higher values of C u and C c whereas ...

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)

Increased particle index value or uncompacted voids in coarse aggregate also provide increased rutting resistance. The latter combine the effect of shape, angularity, and texture. â ¢ The current Superpave specification levels for coarse aggregate angularity have been adopted by 39% of the agencies that specify ASTM D5821 or an equivalent.

With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.
