WebJun 10, 2012 · GP-GM = poorly graded sand with silt. GP-GC = poorly graded sand with clay. The following symbols are used to classify sand (“S” prefix): SW = well-graded sand. SP = poorly graded sand. SM = silty sand (i.e., nonclay fines). SC = clayey sand. In addition, the description of sand with 5% to 12% fines requires the following dual symbols:
WebCoarse grained soils are further classified into gravels (G) and sands (S). The gravels and sands are further divided into four categories according to gradation, silt or clay content. Fine grained soils are those for which more than 50% of soil finer than 0.075 mm sieve size. They are divided into three sub-divisions as silt (M), clay (c), and ... WebWhat is the range of CBR value for a very poor soil? CBR values for common soil subgrades can be estimated according to the USC soil types, for example: clay around 2%, sand from 7% (poorly graded) to 10% (well graded), well graded sandy gravel 15%, clayey sand 5-20%, silty gravel 20-60%, gravel from 30-60% poorly-graded to 40-80% if well-graded.
WebClay soils will cohere strongly. Sandy soils tend to fall apart. Particle size: Measured as the diameter of the particle. Sizes in soil are grouped as followed of: clay greater than 2 micron (0.002mm) silt 2 to 20 micron; fine sand 20 to 200 micron; coarse sand 200 to 2000 micron. Permeability: Rate at which water will move through soil material. WebCoefficient of uniformity, Cu and the coefficient of curvature, Cc, are the parameters based on D-size to define grading. Coefficient of uniformity, and coefficient of curvature, Where D. Cu = D 60 / D 10. Cc= (D 30) 2 /D 10 ×D 60. Where, D 10 — Particle diameter at which 10% of the soil mass is finer than this size.
