摘要
This paper presents the development of a bitumen-stone adhesive zone damage model for the design of ravelling resistant porous asphalt concrete. New set-ups that allow fatigue characterization at meso-scale on the adhesive zone were developed. Use was made of the Dynamic Mechanical Analyzer (DMA) and Dynamic Shear Rheometer (DSR). A damage model was proposed based on a linear damage rule to explain the damage behavior of the adhesive zone in combination with the Mohr-Coulomb failure criterion. The proposed model allows to translate complex adhesive zone stress signals obtained from finite element modelling into life expectancies. (C) 2011 Elsevier Ltd. All rights reserved.
