PROCESS OF MAKING BALLAST-FREE SUPERSTRUCTURE AND BALLAST-FREE SUPERSTRUCTURE MADE IN SUCH A MANNER

摘要

In order to produce a chipless superstructure, an asphalt backing layer (3) is applied to the sub-base of the rolled concrete layer (2), and sleepers (5) are laid on the asphalt backing layer (3) and are provided with a recess on their underside (4). ). In order to secure the sleepers (5) against transverse forces and to ensure tight and wear resistant anchoring, the sleepers (5) in the middle are provided with a through hole (8) and underlaid with a blind hole (9). An adhesive is introduced into the blind hole (9) and then an anchor pin (13) is inserted into the blind hole (9), which is guided by the spacer and sliding sleeve (11) inserted into the through hole (8).
