Abstract:
THE TRIAXIAL-COMPRESSION TEST CAN BE USED TO DETERMINE THE FUNDAMENTAL STRENGTH CHARACTERISTICS OF MATERIALS USED IN THE CONSTRUCTION OF FLEXIBLE PAVEMENTS. BY DETERMINING THE STRENGTH PROPERTIES OF SURFACE, BASE COURSE, SUBBASE, AND SUBGRADE MATERIALS BY THIS MEANS, AN OPPORTUNITY IS AVAILABLE TO UTILIZE THESE MATERIALS ON A BASIS OF RESISTANCE TO STRAIN AND SHEAR, COMPARABLE TO THE METHODS USED FOR OTHER STRUCTURAL MATERIALS, SUCH AS STEEL, CONCRETE, AND TIMBER. THE THEORETICAL REQUIRED THICKNESSES OF PAVEMENT, AS DETERMINED BY THE RESULTS OF TRIAXIAL TESTS ON FIVE TYPICAL SOILS OF THE DRIFT-COVERED AREA OF INDIANA AND ON SEVERAL SOIL-AGGREGATE MIXTURES, WERE OBTAINED AND COMPARISONS OF THE TWO METHODS WERE MADE. THE EFFECTS OF COMPACTION AND RATE OF APPLICATION OF LOAD DURING TEST ON THE THEORETICAL REQUIRED THICKNESSES OF PAVEMENT WERE INVESTIGATED. THE EFFECTS OF THE VARIABLES, SURFACE TEXTURE (ROUNDNESS OR ANGULARITY OF PARTICLES), DENSITY, AND GRADATION, ON STRENGTH CHARACTERISTICS OF BASE COURSE MATERIALS WERE INVESTIGATED. /AUTHOR/
