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

摘要

The goal of this article is to determine the effect of variousmaterial parameters to the fatigue life of the pavement struc-tures. Nowadays many types of mixtures can be built in the pave-ments, with different stiffness moduli. However, the Hungarianasphalt pavement design method can not handle that. The maincause of failure of the asphalt layers is supposed to be caused bythe strains coming from the horizontal tensile stresses at the low-est level of layers. Many calculations were made with variousattributes of the layers of the pavement structures i.e. subgrade,base course, binder course and surface course. After these cal-culations, we can clearly see which parameter of which layer isthe most important to build a pavement with long fatigue life.
