More About Materials Sold and Accepted at Miles River Sand & Gravel
Construction aggregates, including sand and gravel as well as limestone, are vital components for all building and infrastructure needs. While aggregate is used primarily in asphalt and concrete (94% of asphalt pavement and 80% of concrete is aggregate), virtually all construction in America involves the use of aggregate.
Processed Gravel - Man-made gravel with controlled amounts of clay, sand & stone. Stone size is controlled, allowing full control over the composition of the final product.
- According to a case study conducted by the Natural Stone Council, each year the construction industry generates over 160 million tons of waste that includes stone and concrete. The Environmental Protection Agency (EPA), states that environmental stewardship is the responsibility for environmental quality shared by all those whose actions affect the environment. Environmental stewardship is designated as a major focus area for several government agencies and the overall ‘green’ strategic plan.
- Raw materials for crushed stone come from a number of sources, and any given load can contain a mix. Using crushing equipment and screens, Miles River Sand & Gravel break the rock up into small chunks.
- Screening is the separation of material into different sized products. The material is separated by passing through a vibrating 'screen box' which has a number of different sized screens, or meshes which the material falls through like a sieve. The material falls onto conveyors which stock piles the end products. These end products can then be used in the building and construction industries.
- A rich, crumbly soil containing a relatively equal mixture of sand and silt and a somewhat smaller proportion of clay. Gardeners are often advised that a loamy garden soil is best for just about all plants
– Sand consists of tiny particles of rock between 0.002 and 0.08 inch in diameter, which is about the size of a grain of salt. In the natural world, sand results from larger particles of rock that has been weathered down to this size. Most commonly, sand contains igneous rocks, such as quartz, feldspar and mica, which come from a granite source. Sand also can be made mechanically by crushing larger pieces of rock.
- Gravel particles are larger than sand, ranging from 0.08 to 4 inches in diameter. It can be further classified by diameter size as granules (0.08 to 0.16 inches)
, pebbles (0.16 to 2.5 inches)
and cobbles (2.5 to 10 inches)
. Rock particles larger than 10 inches in diameter are considered boulders.
- Crushed stone production was about 1.20 billion tons in 2013, and valued at more than $11 billion, according to the U.S. Geological Survey (USGS). (More can be found at the U. S. Geological Survey and Mineral Resources Program
- A rock is a naturally occurring solid aggregate of one or more minerals or mineraloids.Fill
- Fill dirt is soil obtained from an off-site location and brought to a construction site for the purpose of using it to "fill" holes or serve other construction needs.Stumps
- The base part of a tree trunk left standing after the tree has been felled or has fallen.CRM
- Crushed Road Material, Inch and a half and three inch.Processed Asphalt
- When asphalt road needs to be replaced, the old material can be reused for new construction. This requires less new material, is cost-effective and creates a surface that performs as well as new material.
