Abstract
En muchos países desarrollados, resulta cada vez más habitual el uso de pavimentos drenantes
para la construcción de veredas, estacionamientos y entradas de vehículos, pudiendo ser de asfalto u
hormigón.
El pavimento drenante se produce utilizando componentes convencionales. Es fundamental una elección
sensible de los mismos en su diseño para garantizar durabilidad, satisfacción en su uso y sostenibilidad del
proyecto, dada por su ciclo de vida, costo energético de la obtención de materiales, impacto
medioambiental de su fabricación, su puesta en obra y su uso durante su vida útil. La elección de los
componentes dependerá de las necesidades de respuesta (mecánica e hidráulica), posibilidad de
mantenimiento, tecnología de equipos y materiales disponibles en cercanía a la planta de hormigón o
asfalto o al predio del proyecto, y del presupuesto económico asignado al proyecto.
Este artículo presenta experiencias de hormigones drenantes que incluyen la consideración de los
conceptos de ciclo de vida para establecer un mecanismo de toma de decisión que pueda adaptarse a los
diferentes escenarios constructivos del hormigón drenante y destaca la importancia de la selección de los
materiales componentes.
Los estudios de ciclo de vida en pavimentos drenantes aún se encuentran en etapa inicial, aunque ya es
posible visibilizar que el ACV es fundamental para orientar la planificación y la toma de decisiones en la
elección de los materiales constituyentes.
Abstract: In many developed countries, it is increasingly common to use draining pavements for sidewalks, parking lots and driveways construction, which it can be made of asphalt or concrete. Draining pavements is produced using conventional constituents. A sensible choice of these in its design is essential to guarantee durability, satisfaction in its use and sustainability of the project (given by its life cycle, energy cost of obtaining materials, environmental impact of its manufacture, its implementation and its use during its useful life). The components choice will depend on response needs (mechanical and hydraulic), possibility of maintenance, equipment technology and materials available close to the concrete plant or the project site, and the economic budget assigned to the project. This article presents experiences of draining concrete that include the consideration of life-cycle concepts to establish a decision-making mechanism that can be adapted to the different construction scenarios of draining concrete and highlights the importance of the selection of constituent materials. Life-cycle studies in draining pavements are still in the initial stage, although it is now possible to see that LCA is essential to guide planning and decision-making in the choice of constituent materials.
