Characteristics required for use in the construction of roads and other trafficked areas.
The design of a road is basically conditioning - in addition to the structural assessment - by its resistance to dynamic loads . This type of cyclic phenomena define the durability of the floor itself. This is a function of the limit of exercise, which for a paving can be defined as the time horizon in which they occur cracks or an excess of deformations occur; all these phenomena depend on the nature of the embankment. The research in the field of road embankments tend therefore to analyze the behavior under the effect of repeated loads, that is in conditions similar to those of exercise, in order to design the structure considering the initial construction costs and the maintenance. It is evident that at a lower cost and low initial investment correspond to a greater burden of maintenance and greater discomfort for users. In the design phase, normally the engineers act both on the composition of the layers of the pavement, and foundation materials used, but you can also choose to add elements, such as geotextile Hipertex® , able to perform the function of separation and drainage. Doing this is possible to improve the overall bearing capacity, reducing the permanent deformation and retards of the cracks development.
