    Abstract

    This study provides the theories and viable modelling techniques for predicting and simulating intrinsic causes of delamination failure in Bonded Concrete Overlays. Optimum overlay mixture was formulated using Composite Desirability Analysis (CDA). The experimental treatments considered both structural and elastic stability requirements of the BCOs. Through serial material and interface fracture testing, the optimum overlay material was characterised and used to predict the restraint capacities of the overlay and the interface to delamination failure under Mixed-Mode fracture process. The numerical analysis was implemented using Interface Cohesive Zone Model (ICZM). The FEA results showed that the delamination driving force increases with increase in BCO structural scale and mismatched elastic parameter.
