Considering the joint loading-transfer effect, a 3-D finite element model which consists of thirty full-scale slabs is established. Making the aircraft loads act on different positions and calculating their vertical displacements. The results indicate that the loading area is compressive and the regions far away from loading area are tensile and that the vertical displacement curves change dramatically when aircraft wheels act on different locations.

Considering the future development trend of the airport pavement, a 3-D finite element model with 45m×20m×11.62m full-scale slabs is established to analyze the displacement response of asphalt concrete airport pavement under aircraft loads. Under different aircraft tire pressure levels, the vertical displacement and vertical displacement curve of the pavement in the region between 9 m and 13 m outside aircraft wheels is analyzed. The mechanical response of flexible pavement is studied, and the influence of various parameters on asphalt pavement.

Pavement Response

Purpose Given the importance of airports and the need to develop this issue in runway, the purpose of this study, pavement response values under loading of different aircraft have been obtained using tire and pavement modeling by finite element method (FEM). To predict the actual behavior of pavements under aircraft loading, dynamic analysis of runway flexible pavement was performed using Abaqus software version 6.10. Design/methodology/approach The method is based on finite element analysis and software simulation. And the main goal to obtain the amount of pavement stress and deflection at different speeds. Findings The results of modeling showed that aircraft movement at a speed of 5-8 km/h leads to the highest stresses and deflections in the pavement. Moreover, the effect of elastic modulus variations of the asphalt concrete on the tensile strain under advisory circular layer was calculated for Airbus A380 by using FEM. To validate the results of the runway pavement dynamic analysis, the results of modeling have been compared with the field test results of National Airport Pavement Test Facility. Originality/value Stresses and deflections of pavement during aircraft movement at different speeds of 5, 8 and 20 km/h on the runway have been presented, and the critical points in length, width and depth of runway pavement, as well as the most critical speed of aircraft in terms of induced damage to the pavement, have been obtained.

Safety Operation

Preserving airport pavement means guarantying the safety operation of aircraft movements. There are four aspects that cause progressive pavement deterioration, i.e. the construction design and process, selected material, and maintenance management. One of the traffic aspects, jet engine exhaust, has not been discovered yet. The load pattern of the jet exhaust follows the schedule of aircraft traffic. The assumption held in this research is that the thermal load during aircraft movement may generate a high temperature, which is induced into pavement layers. The objective of this research is to determine the temperature gradient in the pavement, caused by the jet exhaust. This paper discusses the process of determining the temperature gradient in four stages, i.e. by carrying out the gap analysis, evaluation of pavement structures, determination of the load path and the magnitude, and defining the temperature gradient. The temperature gradient in the pavement layer is determined through the development of a model of cyclic loading. The thermal cyclic load follows the aircraft schedule pattern. The pavement temperature receives the thermal cyclic load of the sinusoid of solar radiation. The results indicate that the temperature of the pavement is increased and pavement temperature rises by 35 °C. However, after 60 seconds the remaining temperature of the pavement layer decreases to the initial temperature, which is caused by solar radiation.
