This test is used to determine the bar linear shrinkage of soils. Linear shrinkage is defined as the percent of shrinkage of a soil bar when dried from its Liquid Limit to its Shrinkage Limit.
Data entry and calculations for this test are performed on the Constant Head Permeability form described in the next section. After the data and calculations have been performed the results are displayed in a test report as described in the reporting section below. The format of this report is controlled by the geotechnical template used for the test.
The methodology and calculations for this test adhere to "ASTM D2434-68 Standard Test Method for Permeability of Granular Soils (Constant Head)". For more detailed information on the methodology and calculations please review this standard.
