Wegh Group has expanded the range of products for railway infrastructure, with the approval, by RFI (Italian Railway Network) of concrete sleepers with USP (Under Sleeper Pad).
The pad is applied on the lower surface of the sleeper, or turnout bearers, in contact with the roadbed and it is composed of an attaching surface to the sleeper and a resilient portion in contact with the ballast. The correct positioning of the USP on the lower face of the sleepers takes place automatically with a special machine, approved by RFI and built by Wegh-Techology Division Olmi, which guarantees the quality and homogeneity of the production process. Avoiding the friction between the concrete and the ballast, pad improves the distribution of the loads and allows to obtain a significant increase in the life cycle of the track. The tests required for the approval of these new products have been carried out in collaboration with RINA certification body, and ended by 2016 as planned.
The USP sleepers allow to reduce the frequency of tamping and ballast replacement.
