The Mean Density of Crusher Run approximately 2,200 kg/m.
Crusher run is a type of aggregate made from crushed stone. It consists of various sizes of crushed rock and stone dust, which together create a highly compactable and stable base material. Typically used in construction, landscaping, and road building, it provides a solid foundation for driveways, pathways, patios, roads and building foundations. Crusher run has some useful characteristics:
- Blend of Sizes: Crusher run contains a mixture of crushed stone of various sizes, typically ranging from small fines to larger stone.
- Compaction: The stone dust fills in the gaps between the larger crushed stones, allowing it to compact and become a stable surface.
- Drainage: While compact, it still allows for some water to pass through, helping prevent flooding or pooling.
It's commonly used as a base layer before laying concrete or asphalt, and because of its versatility, it’s a popular choice for DIY projects and construction alike.
USE OF METRIC (Mean Density of Crusher Run)
The Crusher Run Needed for a Lane calculator computes weight (tons) and volume (cubic yards) of crusher run needed for a driveway or lane based on the length and width of the lane and the desired depth of crusher run (crushed stone).
INSTRUCTIONS: Choose units and enter the following:
- (L) Length of the Lane
- (W) Width of the Lane (7' default for truck width)
- (D) Depth of Crusher Run (1.5" default for thin layer)
Crusher Run Needed (CR): The calculator returns the weight of crusher run in tons (U.S. tons = 2,000 lbs) and volume of crusher run in cubic yards. However, both values can be automatically changed to compatible units via the pull-down menu.
The Math / Science
Crusher run is usually delivered via at dump truck, such as the 20 ton truck pictured. An experience operator will spread the stone by chaining the dump door to be open by a few inches. The opening will dictate how thick the stone is laid. A delivery of 22 tons at the farm laid a 7 foot wide swath that was between an inch and two inches deep for about 350 feet in one pass. This is not uncommon.
The volume of crusher run calculation is a simple three dimensional calculation, where
volume = length • width • depth
The weight of the crusher run is based on the formula
where:
- volume is the volume of stone for the driveway or lane
- density of crusher run ( 2195.12 kg/m3)
