Non-Cohesive Soil
By non-cohesive soil, the individual mineral or rock grains form a loose cluster as a result of frictional forces that occur when the grain surfaces rub against each other. The characteristics of non-cohesive soil are influenced by the following parameters:
-
Grain size
-
Grain size distribution
-
Grain shape
-
Grain roughness
Sands, gravels, stones and their mixtures count among non-cohesive soils [ASTM D2487-06] if the percentages by weight of the aggregates with particle sizes < 0.002 in (0.06 mm) are less than 15 % [DIN1054:2010].
Depending on their basic material, these soil types are weather-resistant.
