The rigid pavement is a concrete slab that constitutes at the same time the bearing layer and the means to support and distribute the load. by two layers of granular material of different quality, consists of stone material cemented with asphalt that is covered with the base. marks on the pavement longitudinal and transverse marks. signs in the road longitudinal lines are continuous and interrupted lines, the continuous restricts the circulation in such a way that no vehicle crosses said line or will circulate on it, the dashed lines on the contrary allow to pass by sections on the road., the traffic of a of the roads, must give way to that of the other, this can be achieved by means of luminous signs in each of the roads, when they are not used, the order of crossing can be done with the criterion to be considered preferable the traffic that comes through the Right or indicating the preference of the passage to certain roads., complementary works, complementary plantations, crosses with rotating circulation when converge more than two ways can be the satisfactory solution the order of a crossing of rotating circulation. advantages: they are the circulation within the crossing zone and it is done in only one direction, the exit from the circulation zone is always made turning to the right depending on the traffic capacity of the interaction can be equal to the total vehicular traffic. The main disadvantage is the large space that is needed, another inconvenient is the pedestrian traffic in considerable quantities and make these take a longer route to cross because it does not allow to do so to the central area. crossings of different levels when the intensity of the traffic is great the most perfect form of a crossing to reduce layer levels of the roads and achieve greater safety is to make different levels, sometimes even with traffic not very intense the topographic conditions of the terrain impose this exit as well as the most convenient, crossing at different levels at any angle they cross, the main drawback of this type of crosses is the high cost it has, another is that it does not apply when there is more than one double crossing otherwise it is better it is better to group them by means of secondary roads and main roads, crossing with different levels, crossing with rotating circulation, crossing with highway, canalized intersection, non collinear intersection, diamond crossing, roundabout, trumpet junction, elevated train cut, area of maneuver, superior via, inferior via, metal, simple of concrete, types of slabs, concrete, suspension bridge, arch in half point, wood, of pi edra, classic
