Bulking Factor – EXCAVATION EARTHWORK

26/04/2017  Bulking factor is a ratio comparing the volume of a quantity of moist granular material to the volume of the same quantity when dry. There are many ways of classifying the soil in terms of it’s ease of excavation including seismic techniques. The most common in the United Kingdom at present however is the Ease of Digging scale or diggability. This classifies the soil

Explain the swell factor of soil, Civil Engineering

The swell factor equations are found in the Table below: Swell: A soil increases in volume when it is excavated. Applying the equation, soil with a swell of 25% would have a load factor of 80% (the inverse of 1.25). The load factor can be used to show the relationship between Loose and Bank density by dividing the loose density by the load ...

Impacts of Sand Mining

Sand-and-gravel mining in stream channels can damage public and private property. Channel incision caused by gravel mining can undermine bridge piers and expose buried pipelines and other infrastructure. Several studies have documented the bed degradation caused by the two general forms of instream mining: (1) pit excavation and (2) bar skimming. Bed degradation, also known as channel
