ROCS - the prefabricated slab track of the proven RHEDA 2000® system

The system ROCS has been developed to extend the basic RHEDA 2000® principle - a bi-block precast element monolithically integrated in an in-situ concrete layer - to a system with a higher precast proportion. The monolithic bond between the precast element and the in-situ concrete layer is equally done by means of steel lattice girders half embedded in the precast element and half inside of the in-situ concrete layer for both systems RHEDA 2000® and ROCS. Insofar ROCS follows the philosophy of RHEDA 2000® system in terms of creating a monolithic track slab. The system ROCS is a precast concrete slab that carries two pairs of rail support points. Thanks to its compact design, the panel weighs only around one ton, which means that no special machinery is required to transport, lift and install the system on site. The system ROCS is designed like a concrete highway slab with just shear dowels under the slab joints, which acts at the same time as dummy joints. No other crack width limiting measures are required for the entire system. The ROCS slabs are transversally prestressed to provide the slabs with more stability and safety during production, transport, and installation on site. The regular RAILONE spindle brackets apply to the new system in same manner.
