Abstract:
This paper analyzes the formation, failure mechanism and mechanical properties of the transition layer. And it points out that the interface separation, base layer vertical cracking and surface layer invaded by base layer interface horizontal crack are the three kinds of basic forms of the transition layer failure. The experimental results show that: the transition layer attached on surface layer will decrease the flexural tensile strength and fatigue property of the surface layer concrete; the flexural tensile strength is decreased 0.2～0.4 MPa, trabecular flexural fatigue life is decreased one or two order of magnitudes; setting isolation layer to prevent cement slurry from entering basic layer on the surface of basic layer can effectively prevent the formation of the transition layer thus avoid it from the three kinds of failure modes on pavement structure induced by the transition layer. 3 tabs, 1 fig, 8 refs.
