List of Bulking/Swell factors for various materials. The swell factor expressed in percentage is the amount of volume increase from Bank volume (undisturbed, in place state) to Loose volume (disturbed, excavated state) of the material due to voids (air pockets) added to the material after excavation.
Soil texture—The textural designation of a soil is determined by its relative portions of sand, silt, and clay particles, and indicates which of the three most influence the soil''s, silt, and clay soil properties are obviously dominated by those respective fractions. For example, clay soils (generally more than 40 percent clay) are often poorly drained.
3. If the dispersion percentage is <10% and the soil contains appreciable fines (>5% clay), then the soil may be subplastic. Report this fact and use Particle Size Analysis NonDispersed (P7C/3). 4. The same graph may also be used to derive the ''very fine sand fraction'' (– mm) for calculation of the USLE.
