For various soil types, the heaped capacity is usually about what percentage of the struck capacity?

Heaped capacity is a term used to describe the volume of material that can be carried by a bucket or scoop when the material is piled above the rim, while struck capacity refers to the volume of material that can be contained in the bucket when it is filled to the brim in a level manner.

For various soil types, heaped capacity is typically around 130% of struck capacity. This percentage accounts for the extra volume that can be achieved when the material is dumped into the bucket in a sloped, heaped manner, as opposed to being filled in a flat, even layer.

Understanding this ratio is important for contractors as it affects how much material can be moved in one trip, impacting efficiency and costs. Additionally, the percentage can vary slightly depending on the specific characteristics of the soil being moved; however, 130% is a commonly accepted standard across different types of materials. This knowledge is practical for calculating material quantities and understanding loading techniques in construction projects.
