As the foundation of whole railway track system, railroad track provides a plat for train. In general, railroad track is consists of rail, rail joint, railroad tie and railroad fasteners, etc. Railroad track is also known as track or railway track. As we all know, ballasted track and non-ballasted track are two typical kind of railway track. There are plenty of differences between ballasted track and non-ballasted track, such as composition, construction, maintenance, cost, and so on. As a proportional railway components manufacturer in china, agico Rail contrast ballast track and non-ballasted track.
Ballasted track is a type of traditional railway tracks. Ballasted track is commonly composed of steel rail, railroad tie, railway fasteners and ballast bed. Theoretically, ballasted track is the creation of railway track development. In 1865, the basic structure of the modern track structure was completed. Generally, laying ballast under the railway sleepers to reduce the stress on the ground. A layer of gravel was laid between ground and railway sleeper to form the track bed. Track bed (ballast bed) can improve the flexibility and drainage performance of railway track. Ballasted track also make track easy to repair. The traditional track whose bed is made up of ballast, also called ordinary track and what is often known as ballasted track.
Non-ballasted track, also called ballastless track, is the railway track whose bed is composed of concrete and bituminous mixture, etc. Generally, non-ballasted track is made up of steel rail, railway fasteners and slab. Non-ballasted track’s railway sleeper is formed by concrete casting. Instead of ballast bed, steel rail and railway sleeper is laid on the concrete track. There is no doubt that non-ballasted track is the advanced track technology in the world. Slab track is one of the most important types of non-ballast track structure.
As two common types of railroad track, ballasted track and non-ballasted track both have their merits. When it comes to application, ballasted track is used in the normal speed railway and fast speed railway. Non-ballasted track high speed railway normally adopt non-ballasted track. There are some exceptions, for example, in China and France, ballasted track is individually applied in the high speed railway.
