ABSTRACT
One of the important causes of environmental burdens associated with the construction of transportation infrastructures is the energy consumption and air emissions. It is generally believed that, Warm Mix Asphalt (WMA) technology has advantages related to the reduction of fuel consumption and gas emissions, because it produces asphalt at temperatures https://www.w3.org/1998/Math/MathML"> 20 - 40 ∘ C https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq11794.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> lower in comparison to Hot Mix Asphalt (HMA). In order to quantitatively analyze and compare the environmental impacts of HMA and WMA with the addition of Evotherm https://www.w3.org/1998/Math/MathML"> ⊗ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq11795.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> , an asphalt emulsion, a comprehensive life cycle assessment of asphalt pavements was conducted, except for use stage. The LCA analysis suggested that the increased environmental impacts of the materials used by WMA pavements, especially the impacts of the asphalt emulsion agent, are largely offset by the greater impacts resulting from lowered manufacturing temperature.
