Poorly graded sand characteristics
Soil gradation is a classification of the particle size distribution of a soil. Coarse-grained soils, mainly gravels or sands, are graded as either well graded or poorly graded. Poorly graded soils are further divided into uniformly-graded or gap-graded soils. Fine-grained soils, mainly silts and clays, are classified according to their Atterberg limits. A well-graded soil is a soil that contains particles of a wide range of sizes and has a good repres… WebApr 13, 2024 · They were clay sand (SC) for P1, P2, P5 and SPmG, silty clay (SC) for P3 and poorly graded sand (SP) for P4 according the USCS classification, with low plasticity (CL) for P1, P2, P3 and P5 and high ...

WebCrushed gravel and sand with angular particles have higher friction angle due to better degree of interlocking than the bank run gravel and sand with rounded particles. 3. Gradation: Well-graded soils can be compacted to higher density, leading to better degree of interlocking and higher friction angle than that of poorly graded soils. 4. WebGranular soils consisting of well graded materials (GW, SW) furnish better compaction results than the poorly graded soils (GP, SP). Fine grained soils can also be compacted. For most construction projects of any magnitude, …
