Abstract : Pavement engineers have not been able to predict the performance of pavement systems prior to actual construction and operational utilization. A solution to this problem was obtained by verifying the following hypothesis developed from energy concepts: A functional relationship exists between the cumulative energy as measured by cumulative peak deflections imparted to a given pavement system and the condition of that system. Because of the paucity of airfield condition and deflection data, indirect means has to be used to test the working hypothesis for airfield pavements. Traffic records and construction histories for two Air Force Bases were analyzed, and indicated a threshold cumulative total peak deflection at which cracking develops in airfield pavements.
