Nettetcoefficient of linear extensibility (COLE) or a potential volume change (PVC or swell index). Numerous methods have been proposed in the pastto measure shrink –swellpotential of expansive soils (Franzmeier and Ross, 1968; Grossman et al., 1968; Yule et al., 1980; Schaffer and Singer, 1976; Ross, 1978; Groenevelt and Grant, 2004; … NettetExtensibility can be determined by use of an ‘‘extension diagram,’’ where the drawdown force needed for elongation of an extruded strand is measured as a function of a slowly …

Nettet14. mar. 2024 · Linear extensibility is used to determine the shrink-swell potential of soils. It is an expression of the volume change between the water content of the clod at 1/3- or 1/10-bar tension (33kPa or 10kPa tension) and oven dryness. Volume change is influenced by the amount and type of clay minerals in the soil. The volume change is the percent ... NettetCoefficient of Linear Extensibility — Coefficient of linear extensibility (COLE) is used as a measure of the shrink/swell potential of Vertisols. COLE values between 0.06 and 0.09 are considered HIGH shrink-swell; values greater than 0.09 are considered VERY HIGH. Nettet14. feb. 2005 · Among the methods used to measure soil bulk density, the following have been prominent: paraffin sealed clod (PS), volumetric ring (VR), and the modern methods like gamma ray computed tomography (GCT) and the neutron/gamma surface gauge (SG). The objective of this work was to compare soil bulk density values obtained through … how to score the tinnitus functional index
