The study of geocomposite influence on wearing course asphalt mixture behavior at permanent deformation

Elena Diaconu, Carmen Racanel

Abstract


Following the research, it was demonstrated that can be used the octahedral shear stress theory to analyze the premature deformation that appear in pavement asphalt layers.
This paper has an intention to study the influence of the place of geocomposite under the asphalt layer on the values of octahedral shear stress ratio.
To solve this problem we use the material characteristics obtained in laborator from triaxial test and an analyze of stresses and strains state in pavement structure, with and without geocomposite obtained using an elastic linear software.
The conclusion that can de drawn is the following: the placement of geocomposite lead to smaller octahedral shear stress ratio values in wearing course than in the case of structure without geocomposite.
