Uso de escorias de alto horno y acero en mezclas asfálticas: revisión

Abstract

En la fabricación de mezclas asfálticas se consumen grandes cantidades de agregados pétreos de origen natural lo que impacta negativamente el ambiente. Estos agregados pueden ser sustituidos parcial o totalmente por otros que son desechados en escombreras y producidos por las compañías siderúrgicas, como las escorias de alto horno (BFS) y acero (SS). Estos dos últimos materiales poseen propiedades químicas y físicas que los hacen aptos para ser utilizados en múltiples aplicaciones como la construcción, mantenimiento y rehabilitación de carreteras. En el artículo se presenta una revisión del estado del conocimiento del empleo de BFS y SS en la producción de mezclas asfálticas, se describen y definen ambos materiales, se presenta la problemática ambiental, su riesgo toxicológico de uso, sus propiedades químicas y físicas, las ventajas y limitaciones de uso y la forma como han sido estudiados para ser empleados como agregados pétreos de mezclas asfálticas. Con base en la revisión bibliográfica realizada, los autores al final del artículo exponen algunas recomendaciones para continuar los estudios tendientes a sustituir agregados pétreos naturales por BFS y SS en la fabricación de mezclas asfálticas.
