“…For example, Hossain et al (2011) report an increase in the maximum service temperature performance grading (PG) of 6 °C (from PG 64 °C to 70 °C) when the base asphalt cement was modified with 2 % Sasobit ® by weight of asphalt. A similar conclusion is reported by Prowell and Hurley (2005) and Zelelew et al (2013). This increase in the resistance to permanent deformation can produce a significant decrease in the cracking resistance at low service temperatures and fatigue Medeiros et al 2012).…”

In general terms, warm mix asphalt (WMA) technology has great 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 advantageof this technology, at the moment, concerns the environment. At the end of this work, the authors include certain recommendations for future works in order to continue strengthening the development of WMA technology.Keywords: Warm mix asphalt, WMA, manufacturing, design, additives. RESUMENEn términos generales, la tecnología de mezcla asfáltica tibias (WMA por sus siglas en inglés) presenta un gran potencial para ser usada 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.

“…Gandhi et al [13] found that WMA additives did not seem to have any significant effect on the moisture susceptibility of the mixes as they aged but significantly increased the resilient modulus values of the mixes as they aged. Zelelew et al [14] found that plant-produced WMA mixtures exhibited increased resistance to moisture damage, as shown by laboratory evaluations of the mechanical properties of WMA. Sargand et al [15] conducted laboratory tests on core samples and found that WMA mixtures had higher indirect tensile strength compared to HMA mixtures, after 3 months of service.…”

Moisture susceptibility is one of the key issues of warm mix asphalt (WMA). In this research, the moisture susceptibility of asphalt mixtures and binders containing Sasobit warm mix additive was investigated in comparison to that of hot mixture asphalt (HMA) through laboratory aging experiments. The WMA asphalt mixtures were aged in the laboratory at three aging temperatures and times. The moisture susceptibility of the asphalt mixtures was measured through the laboratory immersed Marshall test and freeze-thaw splitting test. The surface free energy (SFE) of asphalt binders extracted from WMA asphalt mixtures was determined by the sessile drop method. The results show that the aging time and temperature have a significant effect on the improvement in moisture susceptibility in terms of both the freeze-thaw splitting strength ratios and the residual Marshall stability of asphalt mixtures containing Sasobit warm mix additive. The SFE of asphalt binders extracted from Sasobit warm mix increased with the aging time and temperature. The moisture susceptibility of the asphalt mixtures and binders containing Sasobit warm mixes was similar to or even greater than that of HMA aging under certain conditions.
