Abstract

This study investigates failure due to interfacial delamination in a bonded concrete overlay system comprising Polymer Modifies Roller Compacted Concrete (PMRCC) overlay and substrate Ordinary Portland Concrete (OPC). Optimum overlay mix was designed using Composite Desirability Analysis (CDA). Intrinsic complex stresses along the plane of the interface resulting from differential length change and elastic mismatched properties between the two bonded layers were investigated. Distinct delamination cases involving variable structural scales were investigated using both laboratory determined fracture parameters and ANSYS zero thickness Interface Cohesive Zone Model (ICZM) concept. The FEA results showed that the restraint capacity of the interface varies as a function of overlay structural scale and its associated mismatched elastic parameters.
