Title: RESULTS OF INDIRECT TENSILE TESTS RELATED TO ASPHALT FATIGUE
Accession Number: 00211768
Record Type: Component
Abstract: THE PURPOSE OF THIS INVESTIGATION WAS TO DEVELOP A CORRELATION AMONG FATIGUE LIFE, MAGNITUDE OF STRAIN, AND INDIRECT TENSILE STIFFNESS FOR 4 ASPHALTIC CONCRETE MIXES PREPARED AND TESTED IN THE LABORATORY. CONSTANT STRAIN FATIGUE TESTS WERE PERFORMED ON 2.5 X 3 X 14- INCH BEAMS AT SEVERAL STRAIN LEVELS TO DEVELOP A STRAIN-FATIGUE LIFE CORRELATION FOR EACH MIX. INDIRECT TENSILE TESTS WERE CONDUCTED ON MARSHALL SPECIMENS AND THE STIFFNESS MEASURED IN THE REGION OF TENSILE FAILURE. STIFFNESS VALUES RANGED FROM 5,431 PSI FOR A FLEXIBLE MIX TO 29,070 PSI FOR AN AGED STIFF MIX. THERE WAS A TREND FOR THE STIFF MIXES TO YIELD SHORTER FATIGUE LIVES THAN DID THE FLEXIBLE MIXES IF AGGREGATES AND GRADATION WERE SIMILAR. THE CORRELATION DEVELOPED BETWEEN STIFFNESS AND FATIGUE LIFE INDICATES POSSIBILITIES FOR USING THE INDIRECT TENSILE TEST TO DESIGN ASPHALTIC CONCRETE WITH THE FLEXIBILITY REQUIRED TO WITHSTAND REPEATED STRAIN APPLICATIONS. /AUTHOR/
