    Abstract
    One of the world's greatest natural resource exploiters relies on the building and materials sectors for physical and biological support. The concept of sustainable development has been around for more than 30 years, and it connects development and the environment. The road industry emits the most greenhouse gases, both directly and indirectly, due to the usage of fossil energy in mining, transporting, and paving operations. As a result, road development contributes significantly to pollution in Sri Lanka's environment. However, the success of environment-friendly road construction is not at a sufficient level in Sri Lanka mainly a low level of attention given to sustainable development. Hence, this research focused on enhancing road construction success through a better understanding of sustainable development. An extensive literature synthesis was carried out to review the concept and key features of sustainable road construction globally and with reference to Sri Lanka. Following that, an expert interview and a survey were used to continue the study using a mixed research approach. Expert interviews and questionnaire surveys were conducted as the data collection method. The data analysis was done through manual content analysis and Relative Important Index (RII) techniques. The findings revealed what are the existing sustainable features in Sri Lankan Road construction and its advantages and disadvantages. Then identify challenges and opportunities of Sri Lankan Road construction for sustainable development. Thus, the applicability of existing sustainable features to Sri Lankan Road construction shall be reviewed further in empirical research.
