Unified Methodology For Airport Pavement Analysis And Design PDF Download

This publication outlines the proceedings of a workshop held in July 1991 at Cambridge, MA. The workshop provided a forum for leading pavement engineers, researchers and materials scientists to present concepts for the formulation of a unified mechanistic methodology for the analysis and design of pavements serving civil aircraft. The need developed from industry's requests for adequate methods to design, analyze and predict performance of pavements serving more demanding aircraft. The publication contains essential elements of papers and reports presented at the workshop. The general agreement was that, given the prevailing state of the art in computer capability, the requirements for increased capacity through more frequent passes and heavier aircraft, and the development of new man-made construction materials, a more realistic and cost-beneficial approach to pavement analysis and design could be accomplished through the use of discrete material elements, faithful representation of actual material behavior and geometry, and dynamic interaction with rates of loading from any gear configuration. The belief was that computer programs capable to perform the task already exist in other areas of engineering mechanics and that they could be tailored for pavement applications. The papers presented would substitute current methods based on empirical data and broad theoretical assumptions with a generally applicable mechanistic approach. The suggested approach would obviate anomalies that result when current methods are applied to certain cross-section configurations.
