Nevertheless, Europe’s current railway infrastructure will not be able to attract, much less accommodate, the anticipated demand unless we solve the main disadvantages of railway transportation versus highway transportation.
As we are anticipating the next boom in investment in railway transportation, conscious of the important role that slab track is to play in that, and aware of the drag on competitiveness caused by the use of commercial systems, ACCIONAConstrucción has promoted the development of its own slab track system. The system is articulated around prefabricated concrete slabs, each of which contains two pairs of prefabricated blocks with premounted elastic fastening.
In order to attenuate the vibrations inherent to slab track and enable adjustment of the vertical rigidity, the FASTRACK system has up to three planes of elasticity of scalable rigidity.
Under-track pad, with standard commercial range of rigidities (60-120 kN/mm), under-block pad and elastic boot surrounding the block/pad assembly. Elastic mat under the slab.
Horizontal efforts are transmitted to the ground by a steel stopper or fastening system, made of two concentric cylinders that slide along each other, allowing the free vertical movement of the slab.
Additionally, to enable optimum adaptation to potential deformations in the ground, the system will be installed on a 160 mm thick asphalt sub-base.
Over the last decades, there has been growing concern regarding environmental pollution in large cities.
The optimisation of the construction process includes the use of tools such as BIG DATA. This tool allows the collection of large amounts of data, its analysis and the prediction of situations based on statistical patterns.
