- Abstract
- In this study, damping performance of polymer concretes was verified. The polymer concretes consisted of epoxy monomer, hardener and aggregates. To improve damping characteristics of polymer concrete, various additives were used. To predict rolling noise reduction performance of the polymer concrete sleepers, the double beam model was investigated. The vibration response was predicted from the effects of supporting stiffness and l oss factor of sleeper. The radiated sound power was predicted using calculated rail vibration response. Finally, radiated sound powers considered effect of moving sound source were compared for rails supported by different polymer concrete sleepers.
