COEFFICIENTS OF RELATIVE STRENGTH FOR IOWA GRANULAR BASE MATERIALS

THE PURPOSE OF THIS INVESTIGATION WAS TO USE THE CONSOLIDATED-UNDRAINED TRIAXIAL TEST TO RELATE UNTREATED AND ASPHALT-TREATED IOWA GRANULAR BASE MATERIALS TO THOSE USED IN THE AASHO ROAD TEST. THE PRIMARY OBJECTIVES WERE TO (A) OBTAIN A MEASURE OF THE RELATIVE BEHAVIOR OF IOWA MATERIALS FROM DIFFERENT AGGREGATE SOURCES FOR COMPARISON WITH 2 AASHO ROAD TEST MATERIALS ALSO SUBJECTED TO THE SAME TRIAXIAL TEST TECHNIQUE AND (B) DEVELOP A LABORATORY TRIAXIAL TEST TECHNIQUE AND FORM OF ANALYSIS TO INDICATE A GRANULAR MATERIALS VARIABILITY FOR ASCERTAINING AN ASSIGNED COEFFICIENT OF RELATIVE STRENGTH. RESULTS INDICATED THAT VOLUMETRIC STRAIN-AXIAL STRAIN RELATIONS WERE APPROPRIATE EVALUATION PARAMETERS FOR DETERMINING COEFFICIENT OF RELATIVE STRENGTH AT WHAT WAS TERMED MINIMUM VOLUME FAILURE CRITERIA; MINIMUM VOLUME IS CONSIDERED AS A POINT OF "PROPORTIONAL LIMIT" WHEN VIEWED IN CONJUNCTION WITH A STRESS-STRAIN DIAGRAM. /AUTHOR/
