- Sensitivity of the Superpave mix design method to different methods for determining the maximum specific gravity Tamyres Karla da Silva Heraldo Nunes Pitanga Taciano Oliveira da Silva Geraldo Luciano de Oliveira Marques Luis Eduardo Causado-Mendoza Dario Cardoso de Lima Ingeniería Hot asphalt mixture Superpavemix design method theoretical and maximum measured specific gravity This study aimed to analyze the influence of different methodologies to determine the maximum specific gravity on the Superpave mix design method. The comparative analysis focused on the volumetric parameters, on the choice of the design particle size and, consequently, on the respective design asphalt binder contents of the studied asphalt mixtures. Regarding the particularities of the research, there were no significant differences in the design binder contents obtained using the two adopted methodologies for determining the maximum specific gravity. From a practical point of view, the adoption of any of the methods interfered little with the results of the application of the Superpave mix design method. This fact demonstrates a quality of this method since similar researches based on the Marshall design method evidences the sensitivity of the protocol for determining the asphalt binder content in relation to the used type of maximum specific gravity. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49663345022 https://www.redalyc.org/journal/496/49663345022/ https://www.redalyc.org/journal/496/49663345022/html/ https://www.redalyc.org/journal/496/49663345022/49663345022.epub https://www.redalyc.org/journal/496/49663345022/movil 10.15446/dyna.v86n211.7771 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.211 Vol.86
