Evaluación mecánica de una mezcla asfáltica tibia (WMA) utilizando aditivos modificadores de viscosidad
Resumen
La tecnología de mezcla asfáltica tibia (WMA) ha sido un incentivo en la industria asfáltica ya que contribuye a minimizar las emisiones de gases de efecto invernadero al medio ambiente, ayudando a reducir el calentamiento global y la huella de carbono. En esta investigación se evaluó experimentalmente el impacto de dos aditivos WMA sobre las características del ligante asfáltico y la mezcla asfáltica. Entre los resultados, se destacó el impacto de los aditivos en la propiedad de viscosidad del ligante asfáltico. Ambos aditivos redujeron la viscosidad a medida que aumentaba la temperatura en la mezcla. Con respecto a las mezclas asfálticas, la adición de aditivos wma tendió a aumentar la densidad aparente, los vacíos llenos de asfalto, la estabilidad Marshall y a reducir el contenido de vacíos de aire. La incorporación de estos aditivos puede reducir entre un 0.2 y un 0.4% el contenido óptimo de betún.
