Gravel for Path or Lane

The Gravel Needed for a Path or Lane calculator computes weight (tons) and volume (cubic yards) of gravel needed for a driveway or lane based on the length and width of the lane and the desired depth of gravel.  

INSTRUCTIONS: Choose units and enter the following:

• (L) Length of Lane
• (W) Width of Lane (7' default for truck width)
• (D) Depth of Gravel (3" default for thin layer)

Gravel Needed (GR): The calculator returns the weight of gravel in tons (U.S. tons = 2,000 lbs) and volume of gravel in cubic yards.  However, both values can be automatically changed to compatible units via the pull-down menu.

The Math / Science

Gravel is a loose aggregation of rock fragments that are larger than sand but smaller than cobbles. It typically ranges in size from about 2 mm to 64 mm in diameter. Gravel can be naturally formed by the erosion of larger rocks over time, or it can be artificially crushed from larger stones.Gravel 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.  

The volume of gravel calculation is a simple three dimensional calculation, where 

    volume = length • width • depth

The weight of the gravel is based on the formula

    mass = volume • density

where:

• volume is the volume of stone for the driveway or lane
• Density of #57 (1.25") Gravel ( 1,429.796 kg/m³)
