As a construction material
Crushed stone is commonly used as a base material for driveways, roads, and patios. It is also used in construction projects to create a solid foundation for buildings and structures. Additionally, crushed stone can be used for landscaping purposes like drainage and decorative features in gardens.
all of the answers are correct
Rhyolite is commonly used in construction as crushed stone for concrete aggregate, road base, and railroad ballast. It is also used in landscaping as decorative rock and in the production of ceramics and glass. Additionally, rhyolite is sometimes used as a gemstone for jewelry.
Pottery wheels were used in the stone age. Wheels were used on small objects, such as toys. There is evidence of carts from the stone age, but they seem not to have been in widespread use, possibly because there were no good materials for axle bearings until bronze became available.
Hand axes were mainly used during the Lower Paleolithic period, which falls under the Old Stone Age, also known as the Paleolithic era. This period dates back to around 2.5 million years ago to about 10,000 years ago.
Crushed stones are typically referred to as crushed stone or crushed rock. These crushed fragments are commonly used in construction and landscaping for a variety of purposes such as making concrete, paving driveways, and drainage applications.
Basalt can be crushed into crushed stone (aggregate), and used as a material in making concrete or asphalt paving.

The density of 13mm crushed stone can vary depending on the type of stone and the compaction of the material. On average, 13mm crushed stone typically has a density of around 1.5 - 2.0 g/cm3.

The Crushed and Broken Limestone industry mines primarily limestone rocks for processing into construction materials such as crushed stone, sand, and gravel. Limestone is a sedimentary rock composed mainly of calcium carbonate and is widely used in various construction applications due to its strength and durability.
The volume of one ton of crushed stone varies depending on the type and size of the stone, as well as its moisture content and compaction. However, a general estimate is that one ton of crushed stone occupies about 0.5 to 0.7 cubic yards. This means that for typical crushed stone, you can expect approximately 1 cubic yard to weigh between 1.5 to 2 tons.
The density of 11.5 mm crushed stone typically ranges from about 1,500 to 1,800 kg/m³ (or 94 to 112 lb/ft³), depending on the type of stone and its compaction. This density can vary based on moisture content and the specific characteristics of the crushed stone material. For precise applications, it’s best to consult the supplier for the exact density of the specific product being used.
