This paper addresses key issues regarding important factors affecting the sustainability and long-term performance of Portland cement concrete (PCC) pavement structures. Key distress types and their associated features are discussed in terms of their effect on performance and sustainability in terms of specific pavement components. Relevant material properties are also identified and discussed as to how they are represented in laboratory and field testing. A process to manage inspection resources is described and illustrated with the aid of a sustainability worksheet. This paper does not represent a guide or a standard for design or analysis.
