Bituminous ballasted track

[edit]

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.[1] 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.[2]
