Rehabilitation of the track formation layer with the RPM 2002 in Romania Using high-output track formation rehabilitation machine
Rehabilitation of the track formation layer with the RPM 2002 in Romania
Rehabilitation of the track formation layer with the RPM 2002 in Romania Existing Situation: • the thickness of the ballast prism range between 0,40 – 1,10 m • formation protection layer range between 0,10 - 0,70 m • earth in the embankment is mainly mixed with clayey silts
Rehabilitation of the track formation layer with the RPM 2002 in Romania Designed solution: • improve the plain line • improve the route geometry in longitudinal profile • improve the track geometry in cross-section • increasing the bearing capacity at the formation level
Rehabilitation of the track formation layer with the RPM 2002 in Romania General work schedule: • Construction period 600 working days • 190 km of complete track renewal • laying of 310.000 new sleepers • installing of 20.000 tons of rails • laying of 150 new turnouts • laying of 600.000 m³ of new formation layers
Rehabilitation of the track formation layer with the RPM 2002 in Romania Stations:

Rehabilitation of the track formation layer with the RPM 2002 in Romania Transport Logistics: Rail bonded transport with MFS spoil wagons
Rehabilitation of the track formation layer with the RPM 2002 in Romania The following advantages can be achieved by using high output track formation rehabilitation machines like RPM 2002: • Insertion of the new formation layer without removal of existing track • Recycling of old ballast • No movements on the substructure formation with machines • Compaction and levelling of substructure formation by RPM 2002
Rehabilitation of the track formation layer with the RPM 2002 in Romania The following advantages can be achieved by using high output track formation rehabilitation machines like RPM 2002: • Possibility of simultaneous insertion of geotextile and /or geogrid and formation layer • Performance of the machine from 40 up to 70 m/h, depending on the thickness of the track formation layer • On 2-tracks sections the train operation on the open track is possible • Short, open excavation pit (approx. 6m long and 1m deep)
Rehabilitation of the track formation layer with the RPM 2002 in Romania The following advantages can be achieved by using high output track formation rehabilitation machines like RPM 2002: • Saving up to 50% new material by mixing recycled material • Reducing the line closure time • No construction of temporary access roads • Assuring a hand back speed of 40 km/h on the rehabilitated track
