APPLICATION OF ENERGY CONCEPTS TO PAVEMENTS

THERE IS A FUNCTIONAL RELATIONSHIP BETWEEN THE CUMULATIVE ENERGY AS MEASURED BY CUMULATIVE PEAK DEFLECTIONS IMPARTED TO A GIVEN PAVEMENT SYSTEM AND THE CONDITION OF THAT SYSTEM. THIS HYPOTHESIS WAS TESTED BY APPLYING IT TO LOAD-DEFLECTION AND PERFORMANCE TREND DATA GATHERED IN THE AASHO ROAD TEST. REGRESSION ANALYSIS WAS PERFORMED TO FIND A RELATIONSHIP THAT PREDICTED THE LEVEL OF THE PRESENT SERVICEABILITY INDEX (PSI) AS A FUNCTION OF THE PAVEMENT PROFILE AND A MEASURE OF THE CUMULATIVE ENERGY IMPARTED TO THE PAVEMENT. FIELD TESTING PROVIDED INSIGHT INTO THE EFFECT OF THE THICKNESS OF OVERLAYS ON THE ENERGY IMPARTED TO A PAVEMENT AND LED TO THE DEVELOPMENT OF A PROCEDURE TO PROVIDE THE THICKNESS OF AN OVERLAY SO THAT THE PAVEMENT WILL PERFORM SATISFACTORILY UNDER AN ANTICIPATED TRAFFIC VOLUME.
