Application of Westergaard Method for assessment of interaction of Hercules C-130 plane on airport pavement

Abstract

The following paper describes original solution and methodology of calculating elastic pavements loaded by aircraft’s leg in arrangement of wheels in tandem.Using Border Load Capacity State Method, the authors have developed nomographs for determining the equivalent load, which could be further applied in Westergaard’s pavement calculation approach. Derived the state-of-the-art equation and nomographs have not been considered yet. For this reason, they are valuable sources of information for aircraft pavement designers.Considering the pavement loaded by military cargo aircraft (HERCULESERCULES C-130), the authors performed calculations of pavement stresses and its deflection in the function of pavement thickness and soil parameters. These computations resulted in obtaining diagrams presenting pavement stress variation in the function of parameters described herein.Diagrams obtained using Border Load Capacity State Method will certainly accelerate the procedure of calculating the construction of stiff pavements loaded by the aircrafts with tandem arrangement of wheels.[b]Keyword[/b][b]s[/b]: concrete airport pavements, capacity limit state method, system wheels in tandem
