This process results in a product that is highly compactable and sturdy, making it a popular choice for various applications.
Crushed limestone is often used as a base material for road and driveway construction. Its compact nature helps to stabilize the surface and provide support to heavy loads, such as vehicles. The smaller particles interlock together, creating a solid and durable foundation.
In addition to its use in road construction, crushed limestone is also commonly utilized in the construction of buildings and homes. It can be used as a base material for laying concrete and asphalt, providing a solid and level surface. It is also commonly used as backfill material for underground utilities, helping to provide stability and prevent shifting.
Crushed limestone is available in a variety of sizes, ranging from fine dust particles to larger rocks. The specific size and grade being used depend on the intended application. It can also be graded and mixed with other materials, such as sand or gravel, to create a customized blend that meets specific project requirements.
Overall, crushed limestone is a versatile and cost-effective material that provides strength, stability, and durability to various construction projects.
The word "crushed" comes from the Middle English word "crusshen", which in turn comes from the Old French word "croisir", meaning "to break into small fragments". The term "limestone" originates from two Old English words: "line" (meaning "flax") and "stan" (meaning "stone"). Over time, the word "line" evolved to "limestone", referring to a type of sedimentary rock that contains high proportions of calcium carbonate. So, the term "crushed limestone" combines the Old French origin of "crushed" with the Old English origin of "limestone" to describe limestone that has been broken or fragmented into smaller pieces.
