Poorly graded
WebWell graded sands (SW) usually also have good bearing capacity. Poorly graded sands and silty sands (SP, SM) have variable capacity based on their density. Some soils containing silts and clays (ML, CL, OL) are subject to … WebA poorly graded soil is a soil that does not have a good representation of all sizes of particles from the No. 4 to No. 200 sieve. A poorly graded gravel is classified as GP while a poorly graded sand is classified as SP. Poorly graded soils are more susceptible to soil liquefaction than well graded soils.
