| 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 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. | en_US |
