DD Form 1212. Laboratory California Bearing Ratio (CBR) Test Data
DD Form 1212 - Laboratory California Bearing Ratio (CBR) Test Data is used to record data from laboratory California Bearing Ratio (CBR) tests conducted on soil samples. This information is essential for assessing the load-bearing capacity of soils for pavement design and construction.
The form consists of sections where users can document details about the soil sample, test type, and the CBR value obtained from the test. It also includes spaces for recording the test procedure, moisture content, and dry density of the soil.
Important fields in this form include the CBR value, test procedure, moisture content, and dry density. Accurate data collection and documentation are crucial for reliable assessment of soil load-bearing capacity.
Application Example: Civil engineers and pavement designers use DD Form 1212 to collect and analyze CBR test data, which is vital for designing and constructing durable pavements.
Related Form: DD Form 1213 is related, as it involves compression tests on unconfined soil specimens.
Alternative Form: ASTM D1883 is a standard test method used for determining the CBR of laboratory-compacted soils.
