ULTRA RESISTANT MONOLITHIC RAILROAD TIES MADE OF REINFORCED CONCRETE IN AN INTEGRAL MANNER WITH OPTIMUM GEOMETRY FOR TRACK BALAST IN REAILROADS.

摘要

The monolithic railroad ties made of concrete have the technology to achieve a high performance during operation. The steel structure is formed by ultra-resistant steel plates embedded into the concrete and cold rolled pre-stressed wires pressed in the end portions of the plates with Chinese button knots that make a synergy with the monolithic concrete for supporting higher loads even when the length of the ties is reduced, also maintaining a prestressed system. The faceted geometry enables an optimal use of the material and increases the adherence of the ballast to the support surface.
