Implementación de escoria negra de horno de arco eléctrico (ENHAE) como agregado grueso en la mezcla asfaltica

Abstract

The various metallurgical processes generate a series of materials, among which is the black slag, being a by-product from steel and waste from the manufacture of cast iron and industrial steel. When carried out a high production of the same, is established in a predominant context the incentivation of its consumption as a potential alternative of incorporation within the composition of the asphalt mixture to subsequently present the consolidation of the components that make up the structure of the layer rolling, in order to generate a positive impact not only to the design of the same, but in environmental aspects, by providing an area of implementation of this type of steel waste; all this supported by a series of laboratory tests that include the study of the basic element petrography, and the response to various real physical and mechanical constraints, implementing material sample (ENHAE) from the SIDERNAL "SIDENAL SA" located in The city of Sogamoso, a municipality adjacent to the city of Tunja, will ensure that the results obtained are suitable for the conditions of Tunja-Boyacá to be implemented in the construction of flexible pavements based on the INVIAS-13 standard.
