© 2021 Elsevier LtdRail operations today have become more difficult due to increasing operating speeds and decreasing maintenance times. Today's higher frequency train loads are more detrimental, and prestressed railway sleepers especially are susceptible to these dynamic loads. Laminated carbon fiber reinforced polyurethane (L-CFRPU) reinforced concrete railway sleeper models (LCR concrete sleepers) have the potential to exhibit higher damping and resonance resistance more economically and practically. In this study, experimental modal analysis was performed on a large number of samples produced to understand the damping characteristics of sleepers. According to the results, new LCR concrete sleepers have extremely higher damping ratios of over 50% and are expected to be beneficial in extending the service life of the railway components, reducing maintenance needs and harmful effects on the environment.
