DESIGN OF FLEXIBLE PAVEMENTS BY THE VISCOELASTIC "VESTRA" METHOD

A design methodology for flexible pavements developed at the Snamprogetti Laboratories of a general viscoelastic type that can take into account both the real properties of materials as they are defined through viscoelastic functions derived directly from laboratory uniaxial creep tests, and the actual loading conditions (i.e., moving vehicles) is described. The method is mainly directed to the solution of individual problems related to the prediction of asphalt layers deformability and hence takes into consideration the mechanical properties of asphalt concretes which can be suitably described in terms of linear viscoelastic theory and can be evaluated by means of experimental techniques easily accessible in most research laboratories. The required measurements and calculations are described, as well as applications of the method to the design of highway and viaduct pavements. The report also includes a description of an experiment verifying this design method.
