Abstract [en]

Asphalt production consumes considerable amount of fuel and electric energy as significant amount of materials (bitumen and aggregates) are blended together for the construction of flexible pavements. Bitumen is used in asphalt as a binder but can also be used as an alternate energy source. Feedstock energy of bitumen becomes relevant in the life cycle cost (LCC) study, as cost of the binder would be reflected in its alternative value as fuel. In this study, a method was suggested to calculate energy content of the bitumen. Importance of choosing electricity not produced in local diesel generators was also demonstrated. Replacing fuel with inefficiently produced electricity for heating the materials in the asphalt plant would result in high environmental impacts. The calculation of feedstock energy and the understanding of efficient energy production and use could be utilized in the life cycle assessment (LCA) of the roads.
