Advanced prefabricated urban slab track systems with application of innovating design methodologies

The main results achieved are the following:
detailed identification of reference performance specification that the new advanced track must have;
design criteria, taking into consideration also specific needs and technical local traditions;
analytical procedures validated that, with advanced finished elements models, consider: structural aspects, soil, track structure, rail interaction and numerical simulation for noise emission and propagation using available numerical codes to contain noise affects;
innovative materials and products (in particular innovative elastomeric mats and reactive concrete silencer);
detailed design, construction and testing methodology for a new advanced track system that reduces vibration adapted to different track-line classification and with technical solutions to contain noise emission;
reliability, availability, durability and easy maintainability of the track system through the use of prefabricated concrete products.

From the results obtained, the system could be easy developed in future without taking into consideration the normal track solutions already available for metro, tram or railways, and also:
high speed train applications for reducing environmental impacts;
small lateral railway walls using specific concrete resonators;
precast elements for external buildings for particular noisy working sites;
special concrete products that can reduce existing vibration and noise emissions.

Economic advantages include:
low cost over the total service life of the track;
low infrastructural costs as a consequence of low weight (this aspects is important for bridges and viaducts);
minimum initial increased cost in comparison with traditional technologies (and they are completely covered taking into consideration only maintenance costs, without considering the environmental aspects).
