“…The total reduction in aggregate extraction, gas emission and energy use was 13%-14% after adding 15% of aggregates derived through recycling [67]. According to the National Asphalt Pavement Association (NAPA) adding 25% RAP to WMA could potentially offset the pavement lifecycle greenhouse gas emissions by 15% to 20% [68].…”

Among warm mix asphalt (WMA) technologies, asphalt foaming techniques offer high potential in terms of decreasing production temperature. Reluctance of manufacturers to introduce this technology is connected with the concerns of a large investment costs. However, there are known additives which, through asphalt foaming, allow a decrease in temperatures by approximately 30 • C; the use of these additives do not involve expensive investment in order to change the asphalt mix production method. These additives are zeolites, that is, minerals of the aluminosilicate group, the crystalline structure of which contains water bound in a specific way. Its release, at mix asphalt production temperatures, causes asphalt foaming. It is currently known that zeolites can be used in WMA, including natural and synthetic zeolites obtained using chemical reagents and waste. This review presents the results of studies of WMA technology, including the effects of zeolite addition on asphalt properties and mix asphalt, as well as related environmental, economic, and technological benefits.

The lower aging rate of the asphalt used to manufacture WMA mixtures is presented as an advantage, since an aged asphalt produces a decrease in the adhesion between the stone aggregate and the binder (increasing the increment probability of the "stripping" phenomenon) and a change in the behavior of the binder and the asphalt mixture from ductile to brittle (due to an excessive increase in stiffness and viscosity).…”

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.

“…In the specific case of bituminous materials used in pavement engineering projects, there exist some limited recent efforts that have conducted comparative Life Cycle Assessments (LCA) of bituminous products (e.g., [30,31]). Nevertheless, these works do not analyze the impact related to the characteristics of the used fuels during the production of the materials and the adopted production processes.…”

Abstract:The objective of this work is to compare the environmental impact of two different hot mix asphalt (HMA) materials used for road construction in Italy. The analyses used a "from cradle to gate" Life Cycle Assessment (LCA) boundary system and the methodology included considerations about raw materials and fuel supply, as well as transport and manufacturing processes. Primary data provided by the producers and secondary data available in the literature were used as part of the analyses. The results suggest that the proposed method offers rigorous criteria for a comprehensive assessment of the environmental impact of HMA materials, which could be used, among others, as an evaluation parameter in public bids.
