Aggregate " is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of HMA and about 70 to 80 percent of portland cement concrete.

commonly used design examples, charts and other pertinent information related to riprap design that has been used and distributed over the years. Section II contains the construction specifications to be used as part of the site-specific design. Add site specific construction specifications as needed.
This specification is for coarse aggregates, intermediate aggregates, fine aggregates, mixed aggregates (both coarse and fine material) and miscellaneous aggregates for use in all types of concrete construction. 1102.2 REQUIREMENTS a. Coarse Aggregates for Concrete. (1) Composition.
blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected. Close to half of the coarse aggregates used in portland cement concrete in North America are gravels;
Stacked gabions are also used to build privacy screen walls (in lieu of fencing).  Use of recycled coarse aggregate in concrete. Recent statistics show that the increasing demand of construction aggregate could reach 48.3 billion metric tons by the year 2015 with the highest consumption being in Asia and Pacific.

Uses of Aggregates Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as dynamic) load, to distribute the load properly to the supporting ground and to drain the water off the surface.
This specification covers quality-controlled graded aggregates that, when hauled to and properly spread and compacted on a prepared grade to appropriate density standards, may be expected to provide adequate stability and load support for use as highway or airport bases or subbases. Coarse aggregate retained on the sieve shall consist of ...
Coarse Aggregates Section 904.03 defines the acceptable limits for all uses of coarse aggregates. Coarse aggregates are divided into classes based on quality requirements as noted on the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which meet the requirements for all INDOT uses.

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.
Provide coarse aggregates for portland cement concrete in accordance with Table 902-1, Table 902-2, and this subsection. A. Slag Coarse Aggregate. Use slag coarse aggregate consisting of iron blast furnace slag or reverberatory furnace slag with a dry (loose measure) unit weight of at least 70 pounds per cubic foot in accordance with MTM 123. 740
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
