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
Following works can be carried out in one operation process:
• Excavation of the old ballast layer
• Cleaning the ballast of cohesive material and metal pieces
• Sharpening and cleaning the pre-cleaned ballast
• Excavation of the remaining formation material
• Levelling the sub grade
• Building in the geotextile
• Inserting and compaction of the formation layer
• Inserting the recycled ballast
• track tamping and recording the achieved track geometry

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:
• 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)
• Possibility of simultaneous insertion of geotextile and /or geogrid and formation layer

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:
• Reducing the line closure time
• No construction of temporary access roads
• Assuring a hand back speed of 40 km/h on the rehabilitated track
• Saving up to 50% new material by mixing recycled material
