Benefit of Using Recycled Plastic in Road Construction in Bangladesh

Abstract: In the Introduction chapter, a comprehensive overview of the entire study is provided. The significance of the research findings, which focus on the utilization of waste plastic components in road construction in Bangladesh, is highlighted. The importance of identifying the challenges associated with infrastructure development and appropriate management of waste in the country has been outlined. These challenges are directly connected with the SDGs ("Sustainable Development Goals") of Bangladesh. The introduction chapter also stated the aim and objectives of the research.
The literature review chapter examines the use of waste plastic in road construction, focusing on local and global efforts in Bangladesh. It discusses the socio-economic benefits, environmental impacts, and technological advancements of incorporating waste plastic into asphalt. Additionally, it addresses the advantages, challenges, and regulatory frameworks influencing the adoption of plastic-modified roads as sustainable construction materials. The chapter also includes a critical analysis of existing literature and presents a conceptual framework with theoretical foundations.
In the Methodology chapter, primary data collection was utilized. The research study has conducted primary qualitative data collection and data analysis. Ten different participants were selected to participate in the interview process. They were provided with a questionnaire that had ten questions. To obtain this research's final aims and objectives, the study has utilized the "Inductive Research Approach." Positivism has been utilized as a research philosophy. As previously mentioned, the study's data collection and analysis process followed was primary qualitative data collection and analysis.
In the 4th chapter of Primary data collection, collected data from the ten different interviewees who participated has been analyzed. Their answers provided were initially analyzed and then critically discussed. Their answers were linked with the sub-sections of the literature review part to obtain the primary aim of the research. As a wholesome finding, it can be stated that according to the answers gathered from the selected interviewees, the utilization of waste plastic materials as one of the associated raw materials will be immensely beneficial to road construction procedures in Bangladesh and other countries. Using waste plastic as a raw material for road construction will enhance the durability of Bangladesh's highways. It will also be immensely cost-effective, boosting the country's socio-economic growth. Another positive impact associated with the utilization of waste plastic in road construction is that the entire environment of the country will benefit as less carbon emission will be generated from this procedure.
The research's primary conclusions, consequences, and solutions for using waste plastic in the Bangladeshi construction of roads are presented in the conclusion chapter. It evaluated the significance of the research's findings for preventing pollution caused by plastic, strengthening the adaptability of infrastructures, and fostering environmentally conscious development. This chapter also suggested possibilities for further investigation and advocacy that would encourage the utilization of waste plastic materials in the road construction procedure in Bangladesh. This chapter also included the limitations of the study, along with a recommendation section.
