This test is used to determine the linear shrinkage of soils. Linear shrinkage is defined as the percent of shrinkage of a soil bar when dried from from its Liquid Limit to its Shrinkage Limit.

 

The data entry and calculations for this test are performed on the Shrinkage Bar Method 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 "Texas Department of Transportation TEX-107-E Determining the Bar Linear Shrinkage of Soils" and "California Department of Transportation Test 228 Method of Test for Lineal Shrinkage of Soils (Bar Method). For more detailed information on the methodology and calculations please review these standards.
