This research project focuses on the systematic classification and analysis of English terminology used in the field of road construction. It aims to develop a structured understanding of the specialized vocabulary, encompassing various aspects of road design, materials, construction processes, and maintenance. The study will involve a detailed examination of existing literature, including technical manuals, academic papers, industry standards, and relevant online resources. The core of the research involves the identification of key terms, their definitions, and their usage within the context of road engineering. The project will also consider the relationships between different terms, the formation of semantic clusters, and the potential for ambiguity or overlap in meaning. Furthermore, the description will include the analysis of the evolution of terminology, noting changes that reflect technological advancements and shifts in industry practices. The project will lead to a comprehensive classification system. The system can be used as a reference for students, professionals, and anyone interested in road construction.
