DEVELOPMENTS IN HIGHWAY PAVEMENT ENGINEERING - 1. CHAPTER 1 - FLEXIBLE PAVEMENT DESIGN

The structural design of flexible pavements deals with the determination of the thicknesses at which layers in the pavement structure have to be used having regard to the materials selected for each layer and the loads to be carried. Following a description of the functions of each layer in a flexible pavement, the main features of empirical and analytical design procedures are reviewed. Factors that influence pavement design including traffic loading, environmental effects, materials properties and criteria of design and performance are then discussed. The selection of models to represent flexible pavement structures and their analysis to give the distribution of stress and strain are considered. This is an area in which enormous developments have taken place in the past 25 years. Reference is made to different ways in which solutions to the equations for multi-layer structures can be obtained. The action of such structures is demonstrated by analyses of 2- and 3-layer structures. Considerable attention is given to the design criteria used in structural design procedures. The chapter concludes by describing current design systems and the various forms in which they are presented. /Author/TRRL/
