DETERMINATION OF THE THICKNESS OF RIGID PAVEMENTS AND RUNWAYS - GENERAL INTRODUCTION AND CRITICAL STUDY OF PAVEMENT DESIGN METHODS

DETERMINATION DE L'EPAISSEUR DES CHAUSSEES ET PISTES RIGIDES - INTRODUCTION GENERALE ET CRITIQUE DES METHODES DE CALCUL

The first part of this report consists of a general introduction to the problems involved in determining the thickness of rigid pavements and runways. The second part, which consists of three sections, deals with the theories of Westergaard and associated theories: they constitute the first phase of a study in progress of pavement design methods. Chapter 1 reviews the hypotheses which are the basis of Westergaard's theories and gives the formulae for stresses and deflections for three typical cases of loading under a single static load. Chapter 2 is devoted to the critical analysis of Westergaard's theory and hypotheses. The modifications made to these formulae, as a result of experimental work, are indicated. The case where the tyre-road contact area is in the form of ellipse is treated also. Chapter 3 is devoted mainly to a discussion of the most unfavourable loading case: some remarks are added on values arising in practice. The appendices contain two charts, which are complementary to the demonstration of Westergaard's formulae, as well as tables of numerical values. /TRRL/
