Thesis Abstract

Abstract
The construction industry plays a significant role in the global economy and is a major contributor to environmental degradation. In recent years, there has been a growing emphasis on sustainability in construction practices, particularly in the road construction sector. This thesis focuses on the application of sustainable materials in road construction as a means to reduce the environmental impact of infrastructure development. The study investigates the potential benefits, challenges, and opportunities associated with the use of sustainable materials in road construction, with a specific focus on asphalt mixtures and pavement design. Chapter 1 provides an introduction to the research topic, presenting the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter 2 presents a comprehensive literature review that explores existing studies, theories, and practices related to sustainable materials in road construction. The review covers ten key aspects, including the environmental impact of traditional road construction materials, the benefits of sustainable materials, challenges in implementation, and case studies of successful sustainable road construction projects. Chapter 3 outlines the research methodology employed in this study, including research design, data collection methods, data analysis techniques, and sampling procedures. The chapter also discusses ethical considerations and limitations of the research approach. Chapter 4 presents a detailed discussion of the findings, including analysis of data collected through field studies, laboratory experiments, and interviews with industry experts. The findings highlight the performance, durability, cost-effectiveness, and environmental benefits of using sustainable materials in road construction. Finally, Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications for practice and policy, and offering recommendations for future research. The conclusion emphasizes the importance of adopting sustainable materials in road construction to achieve long-term environmental sustainability and economic viability in the construction industry. Overall, this thesis contributes to the growing body of knowledge on sustainable construction practices and provides valuable insights for engineers, policymakers, and stakeholders involved in road infrastructure development.
