Sustainable Benefits of Concrete Pavement

Portland cement concrete pavement (PCCP) has long been known as a long lasting, durable pavement surface with low maintenance costs. Although DOT's sometimes consider these advantages by including Life Cycle Cost Analysis (LCCA) in the tender process, currently, they do not consider the many sustainable benefits of using PCCP. Including sustainable performance of different pavement types provides government agencies with a better understanding of the true cost of the roadway structure. This paper looks at the sustainable performance characteristics of concrete pavement by examining and documenting some of its many social, economic and environmental advantages. Some of the social benefits of concrete pavement that are identified in this paper include: reduced potential for hydroplaning and good night time visibility. Several environmental benefits of PCCP are examined and presented including: findings of the Athena Institute study on the life cycle embodied primary energy use for PCCP and hot mixed asphalt (HMA) roadways; findings of several studies on truck fuel savings from traveling on PCCP compared to HMA pavements and the resulting reduction in greenhouse gas (GHG) and smug emissions; and the recyclable nature of PCCP. Use of supplementary cementing materials (SCM) is also be discussed to show how industry by-products such as fly ash, blast furnace slag and silica fume can be used in PCCP to improve performance characteristics and divert their disposal to landfill sites. Economic benefits such and life cycle cost, advantage of two-pavement system and potential for reduced lighting requirements for PCCP are also provided. La deuxième partie illustrera à partir des résultats de l'étude Athena quels sont 1:l'énergie nécessaire et 2: les gaz à effet de serre générés lors de la construction, de l'entretien sur 50 ans et de la considération de l'économie de carburant appliqués aux 16 tronçons types définis par le MTQ dans le cadre du renouvellement de l'orientation sur le choix des types de chaussées.
