REPORT ON FEASIBILITY STUDY

DURING PHASE I, UNCONFINED COMPRESSION (UNIAXIAL) TESTS OF 1 IN. X 2 IN. ASPHALTIC CONCRETE CYLINDER SAMPLES WERE MADE AT THREE TEMPERATURE LEVELS, 73.4 F, 86 F AND 104 F. ACCELERATION FIELDS, ESSENTIALLY MULTIPLES OF GRAVITY, WERE VARIED OVER A WIDE RANGE OF VALUES FOR EACH TEMPERATURE LEVEL. THE VALUE OF THE UNCONFINED COMPRESSIVE STRENGTH WAS DETERMINED FOR A DESIRED TEMPERATURE LEVEL AND ACCELERATION RATIO. IN EACH CASE A LOSS IN STRENGTH WAS NOTED WITH INCREASED ACCELERATION. HOWEVER, AFTER A CERTAIN CRITICAL VALUE OF ACCELERATION IS REACHED THE TREND IS REVERSED AND SOME STRENGTH IS REGAINED, EVENTUALLY APPROACHING AN ASSYMPTOTE AT ABOUT 90% OF THE STATIC UNCONFINED STRENGTH. /FHWA/
