Description	The California Bearing Ratio (CBR) test program is an Excel Worksheet and is part of a complete Laboratory Testing Workbook with a full range of Integrated Geotechnical Soils tests. It reduces data and drafts reports for the CBR test results using ASTM D-1883 test and calculation procedures. Nine specimens over a range of water contents are used per test. After piston load data is entered, the program displays the load-penetration curves to check for non-linearity. If corrections are needed, the user must manually input the corrected stress values. The test report presents the sample information and bearing ratio for each sample and three graphs including CBR vs. Moisture, Density vs. Moisture, and Density vs. CBR. The user must manually draft curves for the range of moisture contents on the Density vs. CBR graph and interpret the data for the desired level of compaction. The X and Y axis on all graphs are user adjustable.
