Splet01. mar. 2024 · The shrink-swell index and the associated laboratory test are routinely used in Australian geotechnical engineering practice. The core shrinkage index described above is sensitive to the initial moisture content of the specimen, which may lead to unreliable estimations of ground movements [13], and the shrink-swell test addresses this limitation.

SpletRecently the loaded shrink/swell (S/S) test has gained popularity for the calculation of S/S index (Iss) since it does not require measurements of soil suctions and assumes a simple linear relationship. To test this assumption, a modified linear shrinkage test (MLS) was used to measure strain at various suction “sign posts”. sleeper fantasy projectionsSplettest values is more than 10 above the mean of the lowest three soaked CBR test values. 7.1.2.
