Unbound and hydraulically bound mixtures - Part 47: Test method for the determination of California bearing ratio, immediate bearing index and linear swelling
The standard specifies the method for the laboratory determination of the California bearing ratio (CBR) and immediate bearing index (IBI). The standard describes the principle of the tests, the apparatus required, the preparation of the test specimens, the curing of the specimens if required, the testing of the specimens, and the expression and reporting of the results. The preparation of the test specimens for CBR and IBI determination is by dynamic compaction using Proctor or modified Proctor compactive effort as specified in prEN 00227411.
