Ballasted tracks generally need periodical track maintenance work, because they are gradually destroyed by repeated trainloads. Enormous expenditure is spent, therefore, to maintain tracks under good conditions. However, the noise levels on slab tracks are about 5dB(A) higher than those of ballast tracks. In order to solve this problem, the authors proposed a low-noise solid-bed track on the asphalt pavement for new railway lines, and carried out performance tests. This paper describes the structure, results of performance tests and basic design of this track.
