Summary
This paper discusses synthetic railway sleeper technology from glass fibers and polyurethane. Fiber-reinforced foamed urethane (FFU) technology was developed in 1978 in Japan. The first field tests were made in 1980 and since 1985 it is a standard product for Japanese railways. A lot of researching and testing has been done on FFU technology already, including the work in 2008 from the Technical University of Munich. Results of this test will be shown in this paper. Since 2004 it is also used in Europe for bridge and switch projects. Included in this paper are examples of the first installations in Austria, Germany, Switzerland, Belgium, Netherland, France, United Kingdom, Serbia and Hungary.
