ANALYSIS OF TRIAXIAL TEST DATA ON ASPHALT CONCRETE USING VISCOELASTIC PRINCIPLES

SOME OF THE POSSIBILITIES AND LIMITATIONS OF THE USE OF VISCOELASTIC PRINCIPLES TO RELATE THE STRESS- STRAIN-TIME PROPERTIES OF ASPHALT CONCRETE HAVE BEEN DISCUSSED IN THE LIGHT OF THE RESULTS OF TRIAXIAL COMPRESSION TESTS. THE CONCEPT OF DEVIATORIC STRESS AND STRAIN, AS IT MIGHT BE USED TO EVALUATE THE EFFECT OF LATERAL PRESSURE ON THESE PROPERTIES, HAS BEEN INVESTIGATED. ACTUAL TEST DATA ARE PRESENTED TO SHOW THAT THIS CONSIDERATION MAY NOT BE VALID FOR ASPHALT CONCRETE, DUE TO THE LARGE EFFECT OF CONFINING PRESSURES. THE USE OF TWO MATHEMATICAL MODELS WITH THE DATA OBTAINED FROM FOUR TYPES OF TRIAXIAL COMPRESSION TESTS IS SHOWN, TOGETHER WITH A COMPARISON OF VALUES PREDICTED FROM VISCOELASTIC THEORY AND THOSE OBTAINED IN THE LABORATORY. IN GENERAL, CONSIDERABLE EVIDENCE IS PRESENTED TO SUPPORT THE VALUE OF THIS FORM OF ANALYSIS IN ITS POSSIBLE APPLICATION TO THE STRUCTURAL ANALYSIS OF FLEXIBLE PAVEMENTS. /AUTHOR/
