Abstract
With recent unprecedented environmental deterioration becoming more adverse worldwide,
discussions by the international community for establishing an appropriate response policy
against this menace has become more urgent. This has led the world to focus on a new
sustainable development agenda tagged Sustainable Development Goals (SDGs). A
significant section of the SDGs focuses on sustainable infrastructure development. Therefore,
the road infrastructure sector cannot be left out of the sustainability agenda since it forms a
significant part of infrastructure development. Though there are a few sustainability
interventions in road infrastructure development, they are limited and unclear. Therefore, the
purpose of this research is to develop an integrated framework to guide the implementation of
sustainable road infrastructure projects in developing countries. The study will adopt a mixed
method approach. Face-to-face interviews on selected representatives of key stakeholders
will be carried out to select and classify, confirm and prioritize a list of sustainability
performance targets that will be identified through literature and past research. A Delphi
technique through questionnaire survey will be used to explore the extent to which the
sustainability criteria and indicators impact or influence on Sustainable road infrastructure
project implementation in developing countries. Through the identification and integration of
different perceptions and priority needs of the stakeholders, as well as key sustainability
indicators and solutions for critical issues, a set of decision-making guidelines will be
developed to promote and drive consistent sustainability deliverables in road infrastructure
projects. The study is expected to provide an innovative and practical framework which will
aid road infrastructure development stakeholders in the implementation of Sustainable Road
Infrastructure projects.
