Abstract (en)

[origin: EP0624697A1] In order to avoid permanent cracks in the case of prestressed-concrete sleepers with post-tensioning which are subjected to high loading, it is proposed to use as stressing reinforcement, in place of the hitherto-used smooth hairpin-shaped stressing bars, those of profiled cold-drawn steel. <IMAGE>
