The effect of stiffness and duration parameters to the service life of the pavement structure

By Péter Bocz


The goal of this article is to determine the effect of various material parameters to the fatigue life of the pavement structures. Nowadays many types of mixtures can be built in the pavements, with different stiffness moduli. However, the Hungarian asphalt pavement design method can not handle that. The main cause of failure of the asphalt layers is supposed to be caused by the strains coming from the horizontal tensile stresses at the lowest level of layers. Many calculations were made with various attributes of the layers of the pavement structures i.e. subgrade, base course, binder course and surface course. After these calculations, we can clearly see which parameter of which layer is the most important to build a pavement with long fatigue life
