Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.

3. Shape of Coarse Aggregate. Coarse aggregates may be round, angular, or irregular shape. Rounded aggregates have lowest water demand due to lower surface area, and also have lowest mortar paste requirement. These properties make rounded aggregate to yield the most economical mixes for concrete grades up to M35.
5.4.1 Determine the density of the coarse aggregate extracted from the RAP using duplicate samples. Calculate the density of the coarse aggregate in the asphalt mixture by using a calculation based on the density of the coarse aggregate determined following 5.1 or 5.2 and the density of the RAP coarse aggregate.
The physical properties of coarse aggregates, such as bulk density, specific gravity, soundness, flakiness, elongation, 10% fineness, and Los Angeles abrasion, were evaluated to assess their suitability for concrete production. The observed percentage loss during the sodium sulphate soundness test was within the acceptable range …
The binder, fine, and coarse aggregate mix ratios in the mixes were 1:1.54:2.4, where the binder consisted of OPC and 10% OPC replacement by silica fume. The eight concrete mixes were prepared and subdivided into two groups. Two control mixes were taken considering the two size ranges of coarse aggregate.
Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. This method covers the procedure for the determination of particle size distribution of fine, coarse and all-in-aggregates by sieving or screening. Apparatus
