Recently 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 ...

reflecting the expansion and shrink of soil such as liquid limit, plasticity index I p and shrink limit, and four direct relative indexes such as free expansion ratio F s, swell shrink ratio P c, swell shrink ratio e p50 under the pressure of 50 kPa and swell shrink total ratio e ps ...
Shrink-swell index ( I ss ) is commonly used as a measure of soil reactivity and it is used in Australian standard of residential footing design to calculate ground movement. The shrink-swell test estimates the strain change per unit suction of an undisturbed soil sample; assuming the strain ...
The paper by Lopes (2007) proposes an alternative method to the now widely used swell/shrinkage index test (AS1289.7.1.1-1992). On the basis of results obtained from his alternative test, the author asserts that the strain versus suction relationship for clay soils is substantially non-linear,...

Tests such as shrinkage limit test, free swell index test, and oedometer tests were performed as per IS 2720 to study the swell鈥搒hrink and consolidation characteristics of locally available soil and the soil treated with incinerated ash. The shrinkage limit of virgin soil, which was initially...
Based on the obtained comprehensive database of results, ten (10) equations expressing relationships among different engineering properties of unsaturated shrink-swell soils in Egypt are proposed and discussed. Also, the effect of some factors influencing of the swelling behaviour of expansive soils in...
Density and severity of problems associated with the presence of shrink-swell soils differ from region to another. Many factors contribute to the problem such as: soil type, soil engineering properties, foundation type, nature of development project, and the extension of development zone.. .etc. ...
Compacted soil specimens were allowed to swell and either shrank fully or partially shrank to several predetermined heights in each cycle. The tests were carried out at a surcharge pressure of 50kPa. The test results revealed that shrinkage of compacted saturated soil specimens to predetermined ...
