Bituminous ballasted track

Bituminous ballasted track is considered an improvement of conventional ballasted track. The main advantage is reduced maintenance, as the ballast will maintain its geometry longer. Other advatages include lower ballast height, which increases clearings under bridges and in tunnels, and reduced noise and vibration. It is primarily used for heavily loaded tracks and high-speed rail.
