Although aggregates are most commonly known to be inert filler in concrete, the different properties of aggregate have a large impact on the strength, durability, workability, and economy of concrete. These different properties of aggregate allow designers and contractors the most flexibility to meet their design and construction requirements.

Uncrushed aggregates such as natural sands and uncrushed gravels produce mixtures with lower stability and decreased durability, whereas a wellgraded aggregate fits together more tightly during compaction, resulting in a lower required asphalt content and improved stability and durability.

Aggregates for Mineral Aggregate Base and Surface Courses shall be crushed stone, crushed slag, crushed or uncrushed gravel, or crushed or uncrushed chert, together with such material as manufactured sand or other fine materials naturally contained, or added thereto as needed to conform with these Specifications.

Concrete's selfweight is a major aspect of a structure's overall weight. Recently, the use of lightweight concrete (nofines, ed and cellular concrete) has been increased. Normally nofines concrete is produced with crushed coarse aggregate of uniform gradation.
