CORRELATION OF INDIRECT TENSILE TEST RESULTS WITH STABILITY AND COHESIOMETER VALUES FOR ASPHALT-TREATED MATERIALS AND DISCUSSION

A STUDY WAS MADE TO DETERMINE THE CORRELATION BETWEEN THE TENSILE PROPERTIES OF ASPHALT-TREATED MATERIALS TESTED IN INDIRECT TENSION AND THE STABILITY AND COHESIOMETER VALUES FOR IDENTICAL COMPANION SPECIMENS TESTED IN THE HVEEM STABILOMETER AND COHESIOMETER. THE PARAMETERS OBTAINED FROM THE INDIRECT TENSILE TEST INCLUDED TENSILE STRENGTH AT FAILURE, ESTIMATED TENSILE STRAIN AT FAILURE, POISSON'S RATIO, AND MODULUS OF ELASTICITY. EACH WAS COMPARED WITH BOTH THE STABILITY AND COHESIOMETER VALUES. THE TECHNIQUES USED TO CHARACTERIZE THE RELATIONSHP BETWEEN THE RESPONSES OF THE HVEEM AND INDIRECT TENSILE TESTS AS (1) NO CORRELATION, (2) A TREND, OR (3) ACCEPTABLE CORRELATION ARE ALSO DESCRIBED IN THE PAPER. THE TEST RESULTS FOR ANALYSES FOUND TO BE SIGNIFICANTLY CORRELATED ARE DISPLAYED IN SCATTER DIAGRAMS, WITH THE TENSILE PROPERTIES OBTAINED FROM THE INDIRECT TENSILE TESTS PLOTTED ON THE ORDINATE AND THE STABILITY OR COHESIOMETER VALUES PLOTTED ON THE ABSCISSA. THE LEAST SQUARES LINES OF BEST FIT BETWEEN THE TEST RESPONSES ARE ALSO PRESENTED IN THE SCATTER DIAGRAMS, ALONG WITH THE REGION WITHIN WHICH 95 PER CENT OF ALL DATA POINTS SHOULD FALL. STATISTICAL SIGNIFICANCE TESTS WERE USED TO DETERMINE WHETHER OR NOT THE RESULTS OF THE TWO EXPERIMENTS COULD BE COMBINED TO ILLUSTRATE GENERAL RELATIONSHIPS BETWEEN TENSILE PROPERTIES AND STABILITY AND COHESIOMETER VALUES. CONCLUSIONS BASED UPON THE CORRELATION RESULTS INDICATE THAT CORRELATIONS BETWEEN THE PARAMETERS OBTAINED FROM THE INDIRECT TENSILE TEST AND THE HVEEM STABILOMETER AND COHESIOMETER VALUES ARE DEPENDENT UPON THE CONFINES OF THE STUDY. IN GENERAL STABILITY CORRELATED WITH POISSON'S RATIO AND TENSILE STRAIN WHILE THE COHESIOMETER VALUE CORRELATED WITH MODULUS OF ELASTICITY, TENSILE STRENGTH, AND TENSILE STRAIN. /AUTHOR/
