ABSTRACT

The cooperation between layers represents one of the current issues regarding road
pavement analysis on their operational behavior by traffic loads. The bond between road
layers, by most of calculation methods is considered perfect. It is hard to say how true
this statement is, but it is expected the fact that it is unlikely for this bond to be
“perfect” for the entire service life of the road pavement.
A road pavement is calculated depending on a certain number of parameters (traffic,
bearing capacity of foundation soil, the characteristics of materials in road pavement
composition, etc.) so that each road layer will only be loaded on its own level of bearing
capacity. Specific stresses and strains are transmitted in different layers depending on
the characteristics of component materials and the bond between them.
The paper aims to examine the hypothesis of the bounding between road layers on
numerical modeling with ABAQUS 6.8-3, a commercial modeling program, based on
finite element method that was widely applied in road pavements analysis.
