Modernization of the railway line No 273 Wrocław Pracze - Brzezinka Średzka – Księginice section.
Gogrid POLGRID BX 30/30 has been used as reinforcement in the structure of railway track road.
To perform the modernization specializated equipment was necessary. AHM 800R Formation Rehabilitation Machine is the only one in Poland and one of the five European machinery for continuous replacement of the subgrade. It’s able to replace from 400 to 600 meters of substructure without removing the rail tracks per 1 day. Machinery moving along a rail track removes waste gravel’s subgrade layer.
