2020-6-18 The aggregate is generally regarded as an inert filler, which makes up 60 to 80% by weight of the concrete volume and 70 to 85% by weight. The unit is divided into two different types: rough and fine. Coarse aggregates are usually larger than 4.75 mm, while fine aggregates are smaller than 4.75 mm.

Multi-digit specifications represent a blend of one or more of the ten basic specifications (i.e. AASHTO 57 is a blend of AASHTO 5 and AASHTO 7). AASHTO Specifications are technically open graded or clean aggregates. • PA Specifications are maintained by PennDOT and most can be found in their “Publication 408”, section 703.

concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate
