● Surface static stiffness up to 12 N/mm²
● Extremely high dynamic efficiency
● Excellent mechanical properties
● Outstand

Main features and advantages

By installing VIAB ballast mats, higher track elasticity can be achieved. Vibrations and structural noise are effectively reduced, and the ballast is protected — more information: Ballast mats are easy to handle, quick to install, and can withstand heavy construction equipment. Combined with special techniques, ballast mats can also be used for renovation work. With over three million square meters installed worldwide, the economic and technical efficiency of VIAB ballast mats is well proven! They have been widely used on high-speed, heavy rail, and short-distance traffic routes.


Advantage

● The most effective way to achieve specific elasticity within a lower ballast height range
● Improvement in track laying quality
● Reduction of vibration and structure-borne noise in the upper ballast structure
● Optimal ballast embedding and improved load distribution
● Quick and convenient installation



Application scenarios:

  • Seismic Isolation for Public Buildings
