Essay

Conventional asphalt concrete roads (e.g., Ukraine) face early deterioration due to the sensitivity of asphalt to weather and traffic loads. This condition means expensive and premature repairs. The main purpose of this dissertation is to explore the possibility of improving the performance of asphalt concrete using fly ash fibers from thermal power plants in China. As a low-cost and environmentally friendly material, fly ash fiber provides an effective environmental response strategy. The dissertation includes an introduction, five chapters, a general conclusion, a list of references, and an appendix. The introduction provides a general description of the research, particularly demonstrating the relevance of the chosen topic, the connection with the scientific program, the purpose, object, and subject of the study etc. The first chapter of the dissertation focuses on the research background and related existing studies on fly ash fibers and hot cast, cold cast, and epoxy asphalt concrete. The second chapter of the dissertation explains the application of the three types of asphalt concrete. Chapter 3 focuses on the experimental equipment's initial material characteristics and data and the three types of asphalt concrete used for the experiments. Chapter 4 of the dissertation focuses on the principles of interaction of materials in modified cast asphalt concrete and epoxy asphalt concrete. Chapter 5 of the dissertation tested cast asphalt concrete and fly ash fiber modified epoxy asphalt concrete. Separate experiments were conducted to select compositions and determine each concrete's physical and mechanical properties, shear resistance, and wear mass loss. In summary, fly ash fibers from a Chinese thermal power plant have been shown to improve the performance of the three types of asphalt concrete in the dissertation. They are environmentally friendly and cost-effective enough to be considered for widespread use.
