| Description: | Technical memorandum Synopsis: This memorandum is a report on the California bearing ratio (CER) test which is part of the California method of design for flexible pavements. The method was tentatively adopted by the Corps of Engineers in 1942 for the design of flexible pavements for military airports. The purpose of the CER test, which is a penetration type test, is to determine a modulus of shearing resistance of soils. The modulus value determined by the test is used in conjunction with empirical design curves (based in part on correlation with field performance) to determine the total thickness of base and wearing course required to protect the sub-grade and base course against shear failure. The CER test may be used in the design of new pavements, evaluation of the load-carrying capacity of old pavements, or as a field control in the construction of new pavements. |
