Title:

LABORATORY FLEXURAL-FATIGUE TESTING OF ASPHALT-CONCRETE WITH EMPHASIS ON COMPOUND-LOADING TESTS

Accession Number:

00210643

Record Type:

Component

Abstract:

THAT ASPHALT-CONCRETE PAVEMENT SURFACES CAN EXHIBIT FATIGUE DISTRESS IN SERVICE, HAS PROMPTED THE INVESTIGATION OF SEVERAL LABORATORY INVESTIGATIONS CONCERNED WITH THE PHENOMENOLOGICAL FATIGUE BEHAVIOR OF ASPHALT-CONCRETE TEST SPECIMENS. IN THIS INVESTIGATION EMPHASIS IS PLACED ON THE COMPOUND-LOADING FATIGUE BEHAVIOR, THAT IS, THE FATIGUE BEHAVIOR DERIVED FROM THE APPLICATION OF MORE THAN ONE STRESS LEVEL TO ANY PARTICULAR SPECIMEN. SUCH MULTILEVEL LOADING IS MEANT TO SIMULATE TO A LIMITED EXTENT THE DIVERSE SPECTRUM OF VEHICULAR STRESSES APPLIED TO A POINT IN THE PAVEMENT SURFACE. LABORATORY EQUIPMENT WAS DEVELOPED THROUGH WHICH SEQUENCE, REPEATED-BLOCK, AND RANDOM LOAD HISTORIES CAN BE APPLIED TO BEAM SPECIMENS. A MODIFICATION OF THE LINEAR SUMMATION OF CYCLE RATIOS HYPOTHESIS /MINERS HYPOTHESIS/ WAS FOUND TO BE APPLICABLE FOR PREDICTING THE ARITHMETIC-MEAN FRACTURE LIVES OF THE TEST SPECIMENS FOR BOTH REPEATED-BLOCK AND RANDOM LOADING. /AUTHOR/
