A basic guide to particle characterization
particle size for a given percentage volume of the sample. Percentiles are defined as XaB where: X= parameter, usually D for diameter a = distribution weighting, n for number, v for volume, i for intensity B = percentage of sample below this particle size 50%, sometimes written as a
Crushing of Soil Particles | Journal of Geotechnical ...
The amount of particle crushing in a soil element under stress depends on particle size distribution, particle shape, state of effective stress, effective stress path, void ratio, particle hardness, and the presence or absence of water. Data are analyzed for single mineral soils and rockfill‐like materials and equations are presented that can ...

Maximum Aggregate Size Nominal Maximum Aggregate Size
24/01/2013 · In the gradation example above, the nominal maximum particle size is 3/4" because the 3/8" is the first sieve to retain more than 10% of the material (11%) under the MS2 definition. In yet another definition, the Asphalt Institute's SP2 guide for Superpave Mix Design defines maximum size as "one sieve size larger than the nominal maximum size".
