CONCRETE SLEEPER AND SOLID CARRIAGEWAY
A concrete sleeper for a solid carriageway, having a fixing block, which is inserted with the upper section thereof into an underside recess in the concrete sleeper, is mounted elastically by a ring produced from an elastomer and which can be inserted with the lower section thereof into a fillable cut-out in a top layer of the solid carriageway. A base made of an elastic material is arranged on the underside of the concrete sleeper.

15 . A concrete sleeper for a solid carriageway, with an anchor block having a step with a downwardly increased diameter, which block is inserted with its upper section into an underside recess in the concrete sleeper and is mounted elastically by means of a ring produced from an elastomer and which can be inserted with its lower section into a fillable clearance in a top layer of the solid carriageway, wherein a base of an elastic material is arranged on the underside of the concrete sleeper, in that the outer edge of the step of the anchor block is rounded and in that the underside recess in the concrete sleeper has a peripheral step, against which the ring lies with its upper outer corner.
16 . The concrete sleeper as claimed in claim 15 , wherein the base consists of EPDM (ethylene-propylene-diene monomer).
17 . The concrete sleeper as claimed in claim 15 , wherein the base has a thickness of 6 to 20 mm, preferably 8 to 14 mm.
18 . The concrete sleeper as claimed in claim 15 , wherein the base is provided with a nonwoven on one or both sides.
19 . The concrete sleeper as claimed in claim 15 , wherein the base has a clearance in the region of the underside recess for the anchor block or is formed as two parts and is arranged only under sleeper blocks or partially under rail beds.
20 . The concrete sleeper as claimed in claim 15 , wherein less than half the radial width of the ring lies on the step of the anchor block.
21 . The concrete sleeper as claimed in claim 15 , wherein the step is rounded.
22 . The concrete sleeper as claimed in claim 15 , wherein less than half the radial width of the ring lies against the step of the concrete sleeper.
23 . A solid carriageway, comprising a number of concrete sleepers as claimed in claim 15 , which are embedded in a top layer or a supporting layer, the top layer or the supporting layer having clearances for the anchor blocks that are filled with a casting compound.
24 . The solid carriageway as claimed in claim 23 , wherein the top layer and the supporting layer are produced from asphalt or in that the supporting layer is produced from concrete.
25 . The solid carriageway as claimed in claim 23 , wherein the concrete sleepers have rail fastenings with means for vertical and lateral compensation and/or a hard intermediate layer of EVA (ethylene vinyl acetate).
