An Assessment on the Current Practices for the Sustainable Construction of Road Infrastructure Projects

In the present day, the implementation of sustainable construction practices in infrastructure projects should not be viewed as a ‘ticking of the box’ or perceived as achieving compliance through implementing the bare minimum of the environmental requirements. Within road infrastructure projects, there has been a lack of inadequate implementation of sustainable construction practices due to various reasons. This study aims to assess the adoption of existing sustainable construction practices in road infrastructure projects using an in-depth literature review technique named as the Systematic Literature Review (SLR) approach. The qualitative data analysis is conducted with the QSR NVivo software. The findings are analysed using this software, highlighting some of the major existing practices for sustainable construction of road infrastructure projects such as various sustainable design practices, sustainable materials practices, government’s participations, and sustainable lighting practices which are detailed in the results section. The results show that there is insufficient research that has focused on sustainable construction approaches in road infrastructure projects especially in developing countries, yet these projects consume a huge number of resources during their construction and post-construction stages. This study enhances the use of more sustainable materials in road infrastructure projects by shedding light on the existing practices applied.
