Abstract (en)

[origin: EP0733738A1] The rail support sleeper comprises a block (2) of reinforced concrete (38) and a visco-elastic bedplate (8). The block upper face takes the rail and its lower face (6) supports the block on ballast. The bedplate covering the lower face acts as an intermediate support between the ballast and the block. The manufacturing procedure involves a visco-elastic plate (18) having the same dimensions as the bedplate is prefabricated. During this phase chippings (27) are regularly distributed and attached onto one face (20) of the plate. The block is made by moulding concrete in a mould and the prefabricated plate integrated with it to form the bedplate. During moulding the plate is placed so that its chipping face coincides with the block lower face so that the chippings are integrated into the concrete.
