¿Qué hemos hecho para conservar nuestras carreteras?

Hoy 5 de abril de 2018 se celebra el día internacional del mantenimiento de carreteras (International Road Maintenance Day). Bajo la etiqueta #IRMD2018 y bajo el lema “Conservar las carreteras es preservar el medio ambiente” muchos colegas e investigadores están aportando su conocimiento e ideas para concienciar de la importancia de conservar nuestras infraestructuras, especialmente las carreteras.

Pues también quiero colaborar con mi granito de arena. A continuación tenéis recopilados los posts y trabajos que sobre conservación de pavimentos hemos desarrollado en nuestro grupo de investigación. Como podréis ver, nuestro grupo se ha especializado en la optimización heurística de todo tipo de infraestructuras (puentes, estructuras de hormigón, pavimentos, etc.), incluyendo la toma de decisiones, el análisis del ciclo de vida y la sostenibilidad social y ambiental. Si alguien está interesado en alguno de estos artículos, y no lo encuentra, que no dude en pedírmelo que se lo mando. Espero que os resulte útil y de interés.

¿Es posible un mantenimiento sostenible de las carreteras cuando apenas existen presupuestos para ello?

A continuación os dejo el enlace a un artículo científico que nos acaban de publicar donde se muestra la posibilidad de utilizar técnicas de optimización heurística para conseguirlo.

Abstract:

Transport sector constitutes the second largest source of global greenhouse gas (GHG) emissions, being the road transportation the main contributor of these emissions. Efforts in the road sector have traditionally focused on vehicle emissions and infrastructure is typically not included in the emissions account. Road environmental impact is estimated to increase by 10% if the stages of road design, construction, and operation were considered. Previous literature has widely study sustainable practices in pavement design and construction, with little attention paid to maintenance. Current state of practice reveals that pavement managers barely consider environmental performance and their evaluations solely rely on technical and economic criteria. This situation creates the need to incorporate, in an integrated manner, technical, economic, and environmental aspects in the design of maintenance programs. The main objective of this research is to develop a tool for the optimal design of sustainable maintenance programs. Given a maintenance budget, the tool aims to maximize the long-term effectiveness of the network while minimizing GHG emissions derived from the application of maintenance treatments. The capability of the proposed tool is analyzed in a case study dealing with an urban pavement network. In comparison to the traditional maintenance policy, the proposed tool designs maintenance programs that increase the average network condition by up to 22% and reduces GHG emissions by 12%. This application also analyzes the effect of different budgetary scenarios in the technical and environmental performance of the network. This application helps pavement managers in the trade-off between budget and network performance.
