Walking and roads are built like this, that their design withstands the load on medium -sized truck vehicles without showing cracks or deformation of the surface of the surface. Material, from which this type of surfaces are made are sometimes less pleasant to use for passers -by (np: concrete cube called trill).
Driving surfaces are adapted to move heavy vehicles on them. They are usually built on small sections as traveling to various outbuildings and other buildings, where it is planned to bring larger amounts of heavy materials. Such roads can be located in this way, that they are inaccessible to the users of the facility, np. in the economic part.
In terms of the type of material used to build the surface and the method of execution, they are divided into: of land, hard, unpaid and hard improved.
The ground surfaces are made of local soil by properly leveling and giving the required decreases. Various materials can be added to the land used for such surfaces by improving mechanical properties, np. permeability, cohesion.
Hard hard surfaces are built with (natural or artificial stones with varying degrees of fragmentation, stones are not connected with the help of binders. Such surfaces are most often made of several layers of aggregates with varying degrees of fragmentation.
Improved hard surfaces are built. (np. ankle, plates), and also from homogeneous masses that do not contain stone aggregates. Such surfaces can be made as single -layer or multilayer.
For plastic and decorative reasons, mosaic combined surfaces are often built. They are often made of many materials requiring different connection methods and different foundations.
