USE OF ELASTIC THEORY TO PREDICT VARIATION IN DEFLECTIONS OF SOME MINNESOTA ASPHALT PAVEMENTS

A BRIEF REVIEW IS PRESENTED OF THE THEORY USED TO ANALYZE REPEATED LOAD TEST RESULTS ON ASPHALT CONCRETE CYLINDERS AND ASPHALT PAVEMENTS. THE ULTIMATE GOAL IS TO COMPARE THE PERFORMANCE OF THE MIXTURE IN THE FIELD TO THE LABORATORY PROPERTIES OF THE MIXTURES. THE EFFECT OF VARIOUS CONDITIONS ON THE PARAMETERS USED IS SUMMARIZED. THE RESULTS OF THE TESTS ON THE CORES ARE GIVEN AND THEN THE METHODS USED TO OBTAIN THE MODULI OF EACH LAYER ALONG WITH THE RESULTING VALUES ARE GIVEN. THE 15-LAYER ELASTIC SYSTEM IS SUMMARIZED AND A COMPARISON IS SHOWN BETWEEN SOME PRELIMINARY PREDICTIONS OF DEFLECTION AND DEFLECTIONS ACTUALLY MEASURED IN THE FIELD DURING THE SPRING AND FALL PERIODS. THE 15- LAYER ELASTIC SYSTEM PROGRAM HAS BEEN ADOPTED TO THE 1604 COMPUTER AND IS BEING USED ALONG WITH PROPERTIES OF THE TEST SECTION'S MATERIALS DETERMINED IN THE LABORATORY AND IN THE FIELD TO PREDICT FIELD DEFLECTIONS.
