Mejoramiento de la carpeta asfáltica a base de escoria siderúrgica para pavimentos flexibles (mezcla asfáltica)

In the world and in our country, research has been carried out in order to improve the behavior and durability of the asphaltic folder of the different roads designed for the intercommunication of the towns. From the asphaltic one, it is necessary to have the same effect as the one of the asphalt mixture, which is positively and sustainably derived from its technical and scientific applicability. Folder and especially to its period of durability. For the analysis of the behavior of the mixtures, the study was based on the design of a hot asphalt mixture (standard) by the Marshall method, which served as reference for the comparison of its physical - mechanical properties with respect to asphalt mixtures added with Certain percentages by weight and / or volume of slag. Concluding in two tentative scenarios when comparing them with sample "A" (standard sample), for the design of the asphalt mixture with steel slag, as sample "B" and "E". According to the results obtained and its relation to Stability - Fluency, adequate able to maintain its shape under repeated loads, making this a flexible pavement suitable for Ecuadorian highways. Sample "B" was determined for its design. This sample complies with the design parameters established with proportions of 37.80% of coarse aggregate (slag), 48.87% of intermediate - fine aggregate, 5.53% of Filler and 7.8% of AC - 20 asphalt cement. Allowing this way to give an alternative solution in its reuse and its problematic concerning its location and final deposit of steel slag.
