In general terms, warm mix asphalt (WMA) technology presents a wide potential for successful use in road works construction projects. However, concerns remain regarding the durability and behavior of WMA mixtures in the long term, which need to be addressed. This review focuses on the technical, economic and environmental advantages and disadvantages. The review concludes that the main advantage, at the moment, of this technology concerns the environment. At the end of this work, the authors include certain recommendations for future works to continue strengthening the development of WMA technology.      

En términos generales, la tecnología de mezcla asfáltica tibias (WMA por sus siglas en inglés) presenta un gran potencial para ser usa-da con éxito en proyectos de obras de construcción de obras viales. Sin embargo, aún existe preocupación en temas concernientes a la durabilidad y al comportamiento a largo de plazo de esta tecnología. Con base en una revisión bibliográfica, el artículo presenta los aspectos más importantes concernientes a la tecnología WMA. Se reportan las ventajas y desventajas técnicas, económicas y ambientales de utilizar esta tecnología reciente. Al final del documento los autores exponen algunas recomendaciones como apoyo para continuar fortaleciendo el desarrollo de la tecnología WMA.
