The quarry is operated on an as required basis and Rapid currently oversees the whole operation from quarry face to stockpiling road base, sealing and concrete aggregates ready for sale by the client.

"Aggregate" is commonly employed in the phrase "in the aggregate," which means "considered as a whole" (as in the sentence "In the aggregate, the student's various achievements were sufficiently impressive to merit a scholarship").

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete.

Asphalt concrete pavements consist of a combination of layers, which include an asphalt concrete surface constructed over a granular or asphalt concrete base and a subbase. The entire pavement structure, which is constructed over the subgrade, is designed to support the traffic load and distribute the load over the roadbed.

For the construction of the WBM roads aggregates are used in the subbase, base and surface course and so the aggregates ... (II) WMM(Wet mix macadam) road construction: Aggregates used are of the smaller sizes, varies between the mm to 20 mm sizes and the binders( stone dust or quarry ... contracts and Modified designbuild (turnkey ...

Generally, CTAM as a road base material is produced by using coarse natural or crushed aggregates and designed as a heavy traffic base or a heavy traffic wearing course. Recently, in order to protect the natural resource and reduce the environmental pollution of solid waste, recycling aggregates, such as crushed concrete and crushed masonry ...

Thousands of years ago, civilizations built entire cities with stone, sand and gravel, and many of these ancient structures exist today. Our construction aggregates are used in a number of ways. As a base material underneath highways, walkways, airport runways, parking lots and railroads.

Hendricks Road Maintenance added 4 in. of new base material and then added the Base One stabilizing agent to the base using a pressurized water tanker. This process was done in two 2in. lifts. The material was mixed using the blade mix method and compacted to density specs.

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.

When the mineral aggregate mixture is bound with cement or lime, the resulting base layer is called a hydraulically bound base layer. Mineral aggregate mixtures used for this type of base layer consist of uncrushed gravel or coarse aggregate, chippings, and crushed or natural sand.
