CBR (California Bearing Ratio) Design of Flexible Airfield Pavements with Case Study

摘要

It is the purpose of this paper to state the fundamentals involved in the design of flexible airfield pavements utilizing the U.S. Army Corps of Engineers CBR (California Bearing Ratio) design method. This paper also discusses concepts that are considered to be prerequisites to any discussion of the subject, including basic pavement theory, aircraft loading effects, subgrade strength, and aircraft characteristics related to design. The CBR method of design is outlined, and an actual design performed in order to more clearly illustrate this method of designing flexible airfield pavements.
