| dc.description.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 amounts if 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 the pollution of Sri Lanka's environment, and as the success of
environment-friendly road construction is not at a sufficient level, mainly a low level
of attention is given to sustainable development in Sri Lanka. Hence, this research
focuses 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 data collection methods. The data analysis
was conducted through manual content analysis and Relative Important Index (RII)
techniques. The findings revealed the existing sustainable features in Sri Lankan
Road construction and their advantages and disadvantages. The challenges and
opportunities of Sri Lankan Road construction for sustainable development were
identified. Thus, the applicability of existing sustainable features to Sri Lankan Road
construction shall be reviewed further in empirical research. | en_US |
