This system consists of proposing a tool for helping the user firstly to size the body of the roadway, with several analytical methods and models \(Pre\-project, Boussinesq, Westgaard, and Burmister\), and secondly, to offer different design possibilities \(thickness and type of the material\) that make up the layers."]
