Abstract


The maximum surface deflection, the maximum horizontal tensile strain (εt) at the bottom of asphalt concrete (AC) layer and the maximum compressive strain (εc) at the top of subgrade are the most commonly used criteria for flexible pavement design. They were used in this study as the basis of measuring the flexible pavement response. The main objective of this paper was to investigate the effect of horizontal force on the behavior of airfield pavement and new reinforced concrete slab during aircraft ground operation. In addition, the effects of various aircraft’s wheel load configurations on the predicted airfield pavement life were discussed. To achieve these objectives, theoretical analysis, using the finite element (FE) programs SAP2000 and (ADINA) were preformed. The research plan includes studying different sections of airfield pavements, where different AC layer thickness and different AC module were used. Based on the work of this study, modulus of elasticity, E1 had a significant effect on the flexible pavement response and the predicted pavement life. There are three forces acting on the pavement through the tire: 1) longitudinal force (LGF), which is the tractive or breaking force, 2) lateral force (LTF) and 3) vertical wheel load (VL). At critical airfield pavement sections, the pavement life decrease significantly due to existence of horizontal forces at these sections. Also, the new reinforced concrete slab gives better results.
