Application of Triaxial Compression Test Results to Highway Soil Problems


The solution of many highway problems requires a knowledge of the stress-strain relationships to be found in various parts of the highway structure including not only the pavement and base course but also the subgrade and foundation soils. Examples of the utilization of this knowledge will be found in the design of retaining walls and bridge abutments (1), the design of cuts and fills (3, 4, 6, 7), the computation of bearing values (5, 8), and the design of flexible pavements (9). One commonly used method of evaluating the stress-strain characteristics of soils, flexible bases, and bituminous pavements is the triaxial compression test. The essential features of this test have been described in detail elsewhere (2).
