APPLICATION OF THE INDIRECT TENSILE TEST TO STABILIZED MATERIALS

THE IMPORTANCE OF THE TENSILE CHARACTERISTICS OF THE SUBBASE OF RIGID PAVEMENTS CAN BE DEMONSTRATED BOTH FROM THEORETICAL CONSIDERATIONS AND FROM FIELD OBSERVATIONS. INFORMATION ON THE TENSILE BEHAVIOR AND PROPERTIES OF TREATED AND UNTREATED SUBBASE MATERIAL IS LIMITED PRIMARILY BECAUSE OF THE LACK OF A SATISFACTORY TENSILE TEST. ON THE BASIS OF A LITERATURE REVIEW CONCERNED WITH TENSILE TESTING, IT WAS CONCLUDED THAT OF THE CURRENTLY AVAILABLE TENSILE TESTS THE DIRECT TENSILE TEST HAS THE GREATEST POTENTIAL FOR THE EVALUATION OF THE TENSILE PROPERTIES OF HIGHWAY MATERIALS. THIS PAPER DISCUSSES TENSILE TESTING, THEORY OF THE INDIRECT TENSILE TEST, AND FACTORS AFFECTING THE TEST. IN ADDITION, THE RESULTS OF A LIMITED TESTING PROGRAM TO EVALUATE THE EFFECT OF SUCH FACTORS AS COMPOSITION AND WIDTH OF LOADING STRIP, TESTING TEMPERATURE, AND LOADING RATE ON THE INDIRECT TENSILE TEST PARAMETERS OF STRENGTH, VERTICAL FAILURE DEFORMATION, AND A LOAD VERTICAL FAILURE DEFORMATION MODULUS FOR ASPHALT-STABILIZED AND CEMENT-TREATED MATERIALS ARE INCLUDED. ON THE BASIS OF THE LITERATURE REVIEW AND EXPERIMENTAL INVESTIGATION, IT IS RECOMMENDED THAT THE INDIRECT TENSILE TEST BE USED FOR EVALUATING THE TENSILE PROPERTIES OF STABILIZED MATERIALS AND THAT THE TEST BE CONDUCTED UTILIZING A 1.0-IN. WIDE STAINLESS STEEL LOADING STRIP, A LOADING RATE OF 2 IN./MIN, AND A TESTING TEMPERATURE OF 77F. /AUTHOR/
