TKUAPAV: A NEW THICKNESS DESIGN PROGRAM FOR RIGID AIRFIELD PAVEMENTS. IN: ADVANCING AIRFIELD PAVEMENTS

The study's goal was to develop a new thickness design program for rigid airfield pavements based on the conventional plate theory approach. The paper reviews the proposed approach that has been implemented in a user friendly computer program TKUAPAV using Microsoft Visual Basic software. Alternative prediction models which are dimensionally correct and applicable to both of U.S. customary system as well as metric system are proposed and verified for the estimation of critical edge stresses. The concept of cumulative damage factor is used to account for the combined damage effects of different aircraft types and departures. The fatigue relationship is in very good agreement with the performance trend of the existing fatigue curves.
