The main objective of RAILSAND was the design of the chemical composition of steel and the development of thermomechanical and thermal treatments to achieve a new type of rail capable of increasing the abrasion resistance of desert sand and preventing corrosion. It was also intended to define an optimal process of chemical reduction of iron smelting slag for the elimination of CaO to the level that allows its use in desert climate infrastructures. Finally, a SW application would be developed to calculate the cost of the life cycle of the lane taking into account the characteristics of the infrastructure, the characteristics of the service (vehicle, speeds, accelerations, adhesion) and maintenance characteristics (for example, costs lane grinding, rail replacement costs, inspection costs).
