This paper is aimed at identifying constructs that influence sustainable road infrastructure project implementation (SRIPI) in developing countries and to predict which of these constructs determine SRIPI outcomes. A sequential mixed-method approach comprising Delphi study and questionnaire survey was conducted amongst road infrastructure development professionals. Multiple regression was utilized in predicting the effects of the 12 constructs in determining SRIPI outcomes. The study established nine constructs (Social sustainability; cultural sustainability; Economic Sustainability; Environmental Sustainability; Institutional Sustainability; Health & Safety; Project Management; Resource Utilization and Management; and Engineering Performance) from literature and three new constructs (public participation, climate change response and stakeholder management) as influential in SRIP implementation in developing countries. The results revealed that eight of the constructs contributions are not significant in predicting SRIPI outcomes. The other four constructs (Stakeholder management; Public participation; Project management; and Resource utilization and management) make a significant unique contribution in predicting SRIPI outcomes.
