<p>A method for manufacturing a resilient rail support block assembly (1), which assembly is adapted to be mounted embedded in or mounted on a railway substructure and which assembly comprises a prefabricated resilient member (10) as well as a moulded block (20) of a suitable mouldable material, preferably of concrete, having a top, a bottom and peripheral wall, said block being adapted for fastening one or more rails on the top of said block. The prefabricated resilient member (10) has an outer tray (12) and inner tray (13) arranged within said outer tray, and comprises a resilient intermediate structure (15) arranged between said outer and inner trays (12, 13). The block is moulded in a block mould into with the mouldable material is introduced and allowed to harden. The block is fixed in the inner tray so as to extend under the bottom of the block as well as along at least a lower region of the peripheral wall of the block. The prefabricated resilient member is used to form a part of the block mould, so that one or more additional mould members combined with said prefabricated resilient member delimit the mould for the block, the mouldable material being introduced into said block mould and thereby adhering directly to the inner tray of the prefabricated resilient member.</p> |
