Sustainability is commonly described as meeting the requirements of today’s society without compromising the ability of future generations to meet their needs. Sustainable practice is laid as a foundation of the current engineering field, and it is also adapted into the road construction sector, where the application of Warm Mix Asphalt (WMA) is one of the most practical approaches currently available. An increased usage of WMA has been spurred by the increased focus on sustainable infrastructure systems. It is known as a practical solution in the asphalt pavement industry to reduce the energy consumption and emissions by reducing the mixing and compaction temperatures of asphalt mixtures (e.g. through lowering the viscosity of the asphalt binder).  It has also significantly reduced the emissions and fumes from asphalt plants and makes the working conditions better for the construction crews and plant operators.  The drastic reductions in temperature have obvious benefits, including cutting the fuel consumption in manufacturing asphalt pavement.  In addition, potential engineering benefits include better compaction of the road, the ability to haul paving mix longer distances, and the ability to pave at lower temperatures.
