Sistemas de certificación para pavimentos sostenibles: Una revisión crítica internacional

Abstract

Roads provide the network in which public development can take place and the economy can progress. Each year public entities invest significant amounts of economic resources for their maintenance and expansion. Coupled with the fact that the transportation sector accounts for 20% of all greenhouse gas emissions globally, it is necessary the resources invested in these networks are done so in the most effective and efficient manner possible. Tackling these issues, various institutions have established systems to quantify the sustainability of roads, such as GreenPave, Greenroads, CEEQUAL and BE2ST-in-Highways. The objective of this study is to establish an understanding of these systems to properly identify their effectiveness, their benefits and their limitations. This will be obtained via a systematic literature evaluation of all relevant academic publications and scheme manuals. The outputs of this study provide an in-depth understanding of these key rating systems, enabling project managers to better implement sustainability straight from the design stage of a project. Furthermore, sustainability is not a theme present in current pavement design manuals. From the evaluation and diffusion of these rating systems, sustainability can be incorporated and made mandatory in all pavement projects.
