Abstract
The life cycle cost analysis (LCCA) of road related projects commonly considers financial investment required for the design, construction, implementation, maintenance, rehabilitation and end of life. Although LCCA has been widely studied over recent years, sustainability has not received enough attention in this regards. No comprehensive sustainability index has been developed to assess the road related projects over the life span in terms of economy and environment. This research aims to develop such an index using the analytical hierarchy process (AHP) to analyze the costs associated with road life cycle from a sustainable perspective to be able to select the best option from a list of alternatives for road related activities. Finally, this index is successfully validated through application of real case studies.
