Special ballastless track systems
for attenuation of vibration
Ballastless system for vibration filtering, compliant with RFI specification DTCSI SF AR 08 002 1
Nominal top of rail height from the top surface of the pavement: 670 mm
Prestressed Concrete Slab:
Compliant with RFI specification DTCSI SF AR 08 002 1
Plan dimensions: 2400 x 4760 mm
Fastening spacing: 600 mm
Vertical, rotational, and transverse adjustment of each rail seat
Reinforced Concrete Additional Mass:
Additional structural mass to achieve the system's natural frequency: f0 ≈ 20 Hz
Plan dimensions: approximately 2500 x 4760 mm
Elastomeric elements:
Closed-cell polyurethane
Between additional mass and pavement
Between additional mass and lateral stoppers
Stoppers:
Internal: between slab and additional mass, made of reinforced concrete
Lateral: ribbed steel plates, anchored to the pavement
Bedding Mortar:
It fills the space between the additional mass and the slab, helping to make them structurally integral.
Reinforced concrete Pavement:
The pavement forms the base of the ballastless track system and distributes the railway loads to the substructure.
Fastening System:
Vossloh 300-1 type. Dynamic Stiffness: k=100 KN/mm
