Due to the varying sizes and haul capacities of dump trucks, load sizes vary greatly and can range from a few cubic yards to hundreds of cubic yards, depending on the truck in question and the material being hauled. Typically, a tandem dump truck can hold up to 18 cubic yards of material.
However, there are different sizes of truck beds, which greatly affects the amount of material able to be hauled. Weight is also a factor, as trucks are loaded according to weight and not volume. If the material is heavy, the bed may not be filled to volume capacity in any one load.
