WebbPlasticity is the putty-like property of a cohesive soil that allows it to be remoulded without rupture. Because higher plasticity soils exhibit this characteristic over a much wider range of moisture contents than do low plasticity soils, the Atterberg Limits are typically the basis on which plasticity determinations are made. Webb27 dec. 2024 · Silt is widespread in the Yellow River alluvial plain; however, its engineering performance (small and uniform particles, high roundness, low plasticity index, poor cohesion, and high liquefaction susceptibility) make it unsuitable for subgrade filling [].To improve the engineering performance of such problem soils as silt, scholars added … Webb19 sep. 2024 · IP = 0.73 (WL – 20).
