Crushed Rock
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from naturally occurring gravel, which is produced by natural processes of weathering and erosion and typically has a more rounded shape. Use * Angular crushed stone is the key material for macadam road construction, which depends on the interlocking of the individual stones' angular faces for its strength. * As riprap * As railroad track ballast * As filter stone. * As composite material (with a binder) in concrete, tarmac, and asphalt concrete. * In landscaping as a groundcover, walkway and driveway pavement, and infill for permeable pavers.

Charmeuse Lime & Stone
Charmeuse (), from the French word for female charmer, is a lightweight fabric woven with a satin weave, in which the warp threads cross over four or more of the backing (weft) threads. These float threads give the front of the fabric a smooth, shiny finish, whereas the back has a dull finish. Charmeuse differs from plain satin in that charmeuse has a different ratio of float (face) threads, and is of a lighter weight. Charmeuse may be made of silk, polyester, or rayon. Charmeuse woven from blended fibers has also become more common. It is used in women's clothing such as lingerie, evening gowns, and blouses, especially garments with a bias cut. It is occasionally used in menswear. Characteristics Charmeuse is lightweight and drapes easily. It has a satin side, which is shiny, and a matte side, which is dull.

Construction Aggregate
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. Aggregates are a component of composite materials such as concrete and asphalt; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost exte ...
