    Circular Economy Practices in Road Rehabilitation and Development in Sri Lanka
    (Faculty of Engineering, 2025-09-09) De Alwis, L. M.; Gunarathna, K A N; Kalugala, C.
    The integration of Circular Economy principles into road rehabilitation and development offers a sustainable alternative to traditional linear construction practices. In Sri Lanka, where road infrastructure is crucial to economic growth and connectivity, the Circular Economy offers opportunities to reduce reliance on virgin materials, minimise environmental impact, and enhance long-term cost efficiency. This study explored applicable Circular Economy strategies, assessed current implementation practices, identified key challenges, and proposed viable solutions to support Circular Economy adoption in the Sri Lankan Road sector. A mixed-methods approach was employed, combining a comprehensive literature review with data from semi-structured expert interviews and a questionnaire survey of construction professionals. The findings indicate that while awareness of the Circular Economy is growing, its practical application remains limited due to barriers such as the absence of standardised technical guidelines, insufficient government incentives, limited stakeholder knowledge, logistical challenges in material sourcing and storage, and reluctance to shift from traditional methods. Data also highlights substantial potential benefits, including cost savings, reduced construction waste, increased material efficiency, and environmental improvements. Participants emphasised the importance of pilot projects, training programs, and policy support in promoting Circular Economy practices. To overcome existing barriers, the study recommends the development of clear Circular Economy specifications, financial incentives, capacity-building initiatives, and the establishment of centralised recycling infrastructure. These strategic actions can facilitate the transition toward a more circular and sustainable approach in Sri Lanka’s Road construction and maintenance sectors.

    Driving Towards Sustainability During the Construction Phase of Roads in Sri Lanka by Mitigating CO2 Emission: A Systematic Literature Review Approach
    (SLIIT, Faculty of Engineering, 2024-10) Yaparathnea, I.H.G.Y.M. Udari; Guruge, K
    Climate change has become a pressing concern for humanity in the contemporary era. Scientists believe that the acceleration of global warming and climate change is directly linked to the rising concentration of greenhouse gases, particularly carbon dioxide (CO2). This has become a challenge for many developing countries. The construction industry is one of the sectors that significantly contributed to heightened carbon emissions into the environment. Road construction involves various activities and processes that release substantial amounts of CO2 into the atmosphere. Addressing these issues are crucial for mitigating the adverse effects of climate change and fostering sustainable development. The development of road infrastructure generates CO2 emissions across various stages. Notably, the construction stage is responsible for a significant portion of these emissions. Despite this, research efforts in Sri Lanka have primarily focused on reducing CO2 emissions in building construction projects, with limited attention to strategies specifically targeting road construction projects. The construction phase of road development has thus far been overlooked in terms of CO2 emission reduction strategies. Consequently, this study seeks to raise awareness among academics, professionals, and practitioners involved in road development projects about the factors influencing CO2 emissions during the road construction phase. The objectives of this study are to examine the factors affecting CO2 emissions during road construction development, identify the activities and processes contributing to CO2 emissions during the construction phase of road projects, explore existing sustainable strategies used in road construction to mitigate CO2 emissions, and assess their applicability to the Sri Lankan Road construction sector. A systematic literature review was conducted to achieve these objectives, selecting the fifty-six most relevant past research studies.
