Today, many developing countries are seeking to increase investment in infrastructure projects to achieve sustainable development. On the other hand, the countries' success in infrastructure and development projects is what constitutes their progress. In recent decades, with the development of high-speed lines, railway transportation has seen major developments, including reduced time of dispatching trains, increased capacity, and, most importantly, increased speed of trains. Considering high-speed lines and limited aerial fleet, most countries have begun to use high-speed trains as the most reliable and most cost-effective method of transportation. Accordingly, this study mainly aimed to examine and prioritize pavement systems suitable to high-speed trains. For data analysis, first, major high-speed train pavement system techniques were identified using library studies, while for the analysis process, experts, including 3 employers, 4 contractors, 4 consulting companies, and 11 academic professors, were interviewed. In this study, 7 most frequent techniques were selected. Then, using the fuzzy DEMATEL method, each of the techniques was scored, and finally, it was determined how each factor affected and was effective on the systems. The findings revealed that the Rheda MRT (B1) system was most affected, with the Studiengesellschaft Asphalt-Oberbau design (B5) method, most effective on the implementation of the high-speed railway pavement system.
