INVESTIGATION OF PRESSURES AND DEFLECTIONS FOR FLEXIBLE PAVEMENTS. DEVELOPMENT OF REPRESENTATIVE SOIL STRENGTHS FROM LABORATORY TESTS

Abstract

This report describes a triaxial test program conducted to establish a test method or procedure whereby stress-strain curves developed from laboratory tests on small samples would duplicate the field data curves. By trial and error it was found that curves developed in variable-confining-pressure triaxial tests on (1) undisturbed samples from the clayey silt test section and (2) prepared samples of sand from the sand test section yielded stress-strain curves duplicating the field data so closely as to be identical for practical purposes. It is believed that a theoretical loading curve can be used with the variable-confining-pressure triaxial test to develop stress-strain relations for soils of the type used in the tests reported, and perhaps for other types as well.
