THE ANALYTICAL DESIGN OF BITUMINOUS PAVEMENTS

The paper describes a practical and implementable analytical procedure for the design of asphalt pavements. The method makes use of the considerable knowledge which exists on the mechanical properties of the materials, together with site and laboratory data. As the main structural layers in the pavement are bituminous, linear elastic theory is used with due account taken of temperature and rate of loading effects. Detailed studies of asphalt pavement design against fatigue cracking and permanent deformation have led to the development of design criteria for both failure modes. Cumulative damage techniques are used to evaluate the interaction of variations in traffic loading and temperature and to determine equivalent annual values of temperature for design purposes. The design procedure is described and reference is made to main frame and micro computer programs which have been developed to apply it. A comparison is provided between designs carried out using this procedure and those in the Shell Design Manual, Road Note No. 29 and the TRRL design method. A brief review is also given of the Asphalt Institute design procedure. The paper also indicates the benefits arising from the use of novel or modified materials with improved mechanical properties developed during this research, which can either increase the life of a pavement or reduce the required layer thicknesses.
