Valuation of Aggregate Operations for Banking Purposes (Sand and Gravel and Crushed Stone) Aggregate consists of sand and gravel and crushed stone. The principal consumers of sand and gravel and crushed stone materials are the highway and building construction industries. The principal construction uses include:
AGGREGATE PRODUCTION This chapter discusses the total process of aggregate production from extraction through processing. Also discussed is the handling, stockpiling, and shipping of the product up to the point where the material leaves the Producer's …
The superheated aggregate is used to heat the RAP materials. The aggregate temperature drops as the RAP material is heated and its moisture evaporated. The recycled mix is brought up to discharge temperature in the last portion of the drum. The parallel flow drum mixers were effectively used for recycling in the '70s and '80s.

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.
Before rock aggregate is mixed with other ingredients to make HMA, it is thoroughly dried. The drying and mixing process can be accomplished with one piece of equipment or the functions can be separated. Mixing can take place in a continuous process or in a batch process.

A process flow diagram for construction sand and gravel processing is presented in Figure 11.19.1-1. The following paragraphs describe the process in more detail.
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes.

MAERZ Rock Mechanics and Explosives Research Center, University of Missouri-Rolla Abstract Aggregate size and shape measurements are increasingly becoming important issues in the mining, comminution, materials handling, and construction industries.
and drying process move toward the upper end of the dryer, against (counter to) the flow of the aggregate. As the aggregate is tumbled through the exhaust gases, the material is heated and dried. Moisture is removed and carried out of the dryer as part of the exhaust gas stream. The hot, dry aggregate is then discharged from the dryer
