Resumen

La rehabilitación de carreteras supone un desafío clave para promover el progreso socioeconómico, mejorar la seguridad vial y preservar el medio ambiente. La tecnología de autorreparación de mezclas asfálticas mediante calentamiento por microondas extiende la vida útil de los pavimentos, reduciendo el consumo de combustibles fósiles y ahorrando el uso de recursos naturales durante su vida útil al aprovechar las propiedades termoplásticas y dieléctricas del asfalto para cerrar grietas en pavimentos dañados sin destruir la estructura original. En este estudio se llevado a cabo un Análisis de Ciclo de Vida para determinar los beneficios ambientales del uso de esta tecnología cuantificando sus impactos potenciales y se han comparado diferentes escenarios en los que varía la energía microondas y la adición de escorias. Los resultados muestran que esta tecnología podría disminuir una cantidad considerable de emisiones durante el ciclo de vida en comparación con una carretera convencional.
