A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of sleepers and ballast is replaced by a rigid construction of concrete or asphalt.

The design of a ballastless track is generally made up of the following components: rail; rail fastening; sleeper; concrete or asphalt base layer; hydraulically bound base layer; frost protection layer; subsoil; Over the years, different types of ballastless track have been developed.

The monolithic, ballastless RHEDA 2000® system represents the most advanced stage of development in the RHEDA family. This system is used for mainline tracks, especially on high-speed routes. Chief characteristics of the supporting concrete slab include its lack of a trough, and its use of a modified bi-block sleeper with a lattice truss.

Ballastless track systems: top performance on a firm foundation Rail traffic is reaching out toward new horizons on ballastless track systems. The arguments are indeed convincing: long life cycles, top speed, ride comfort, and great load-carrying capability.

RHEDA 2000® combines high levels of safety and long-term track positioning, with favourable construction costs and low maintenance expenses. The system accordingly fulfils all re-quirements for application on heavily travelled high-speed rail lines, and simultaneously assures optimal ride comfort.

Chinese standard 55Q 30kg/P30 railroad track. The ballastless track design generally consists of the following components. Rail. rail fasteners. rail sleepers. Concrete or asphalt base. hydraulically bonded subgrade. Frost protection layer. Subsoil. largely maintenance-free. Reduced maintenance costs. Increased capacity.

As axle loads and speeds constantly increase in rail transport, new track systems are being developed. One such development is the ballastless track system. Today there are several types and variations of slab tracks, but how do they differ, and which one is the best? This thesis

Dec 1, 2017 · The state of the art of ballastless track for switches, important information on details concerning drainage, transitions, accessibility for road vehicles and experience gleaned from maintenance round off the work.

Feb 5, 2021 · Ballastless track support structures are regarded as possible solutions to the problems of track maintenance and the research and development of these structures is reviewed. The new types of structures include ties embedded in concrete slabs and also beams.

Abstract: This Paper presents the Analysis and Design of reinforcement at the top and at the bottom of the slab, this Ballastless Track Slab for 17t railway loading. Ballastless Track improves the bending strength of the track structure.
