INVESTIGATION OF ADHESION PROPERTIES BETWEEN ASPHALTIC-CONCRETE LAYERS

The state of adhesion at the interfaces between the various layers of flexible pavements affects the performance of flexible pavements through its influence on the stressing level of the materials. According to available solutions of stress distribution in the interface regions is highly influenced by the adhesion conditions at these interfaces, and especially at the upper layers of the pavement. The knowledge of the degree of adhesion, especially in the interfaces at the upper layers, is essential. This paper deals with the adhesion properties at interfaces of asphaltic layers derived from laboratory test results. Solutions of stress distribution in the elastic and the plastic state are presented, indicating the influence of the material parameters, as derived from the tests on the overstressing and failure phenomena.
