Quality of Infrastructure became indispensable to the innovation-driven development.
Poor infrastructure quality means more extra costs for operation and maintenance, in addition to unstudied
impacts on the surrounding environment and society. To eliminate the bad impacts and the
extra costs, sustainability must be applied in all infrastructure projects. Sustainability represents one
of the latest degree subjects that have various trials to connect the social science with the
engineering and the environmental science with the future technology. The objective of this
research is to provide an integrated sustainable evaluation system (ISES) for quantifying all impacts
of road projects. The proposed evaluation system took into consideration the different phases of
project including construction phase and operational phase. The different impacts of road projects
were divided into three main classifications; the project economic costs to include costs of project
construction and operation; the environmental impacts; and the social impacts. Furthermore, a real
case study was discussed to validate the research methodology, where it was concluded that the
environmental and social impacts have the main impact on project decision and according to the
ISES value, the case study road has a sustainable impact on the surrounding environment and
society.
