Abstract
The purpose of this study was to examine the validity of Durability Index (DI) based performance specifications as a practical approach in the control of quality, with regard to durability, in reinforced concrete structures. The DI-based specifications entail provisions for limiting values on the relevant DI test parameters (oxygen permeability index (OPI), water sorptivity index (WSI) or chloride conductivity index (CCI)) and cover depth, depending on exposure conditions for a given service life. These specifications have been implemented by the South African National Roads Agency Limited (SANRAL) in major infrastructure projects e.g. the Gauteng Freeway Improvement Project (GFIP), which provided the main case studies considered in attaining the research objective.
