CONSTRUCTION AND EXPERIENCE OF ASPHALT BASED TRACK ON BRITISH RAILWAYS

This paper describes the design and construction of an experimental asphalt based track installed by the Research and Development Division of British Railways in collaboration with Esso Research Centre. The track construction comprises a 230 mm thick asphalt base overlying a sand blanket on a marl formation, supporting four different types of concrete superstructure to which the rails are fixed. Details of the various types of track superstructure are described together with measurements of the strains in the asphalt under test trains and their relation to theoretical strain predictions. The overall performance of the asphalt based tracks so far has been good and in particular the retention of the initial track geometry under traffic has been excellent. The initial costs were higher than those of conventional ballasted track, and the paper concludes with some ideas for reducing the costs of asphalt based tracks.
