ANALYSIS OF STRESSES IN FLEXIBLE PAVEMENTS AND DEVELOPMENT OF A STRUCTURAL DESIGN PROCEDURE

A PROCEDURE IS DEVELOPED FOR THE ANALYSIS AND DESIGN OF FLEXIBLE PAVEMENTS, BASED ON THE PREMISE THAT THE LATERAL STRESS PRODUCED IN THE PAVEMENT STRUCTURE BY SURFACE LOADS MUST NOT EXCEED THE PASSIVE LATERAL RESISTANCE PROVIDED BY THE COMPONENTS OF THE PAVEMENT STRUCTURE. STRESS CONSTANTS OF COHESION, C, AND ANGLE OF INTERNAL FRICTION, OBTAINED FROM A STRENGTH ENVELOPE FOR THE FLEXIBLE PAVING MATERIAL DEVELOPED FROM TRIAXIAL OR DIRECT SHEAR TEST DATA, ARE THE PREDOMINANT FACTORS INFLUENCING THE RESISTANCE OF THE PAVING MATERIAL TO DEFORMATION. THE PROCEDURE IS APPLICABLE TO THE STABILITY ANALYSIS OF BITUMINOUS MIXTURES OR TO THE THICKNESS DESIGN OF THE PAVEMENT. EXAMPLES ARE GIVEN TO ILLUSTRATE THE APPLICATION OF THIS DESIGN PROCEDURE. /AUTHOR/
