The word "border" in French translates as "edge", "frame" or "border". In construction, "road curb" is the name of the profile divider between the sidewalk and the carriageway. Relatively recently, it was not possible to purchase this product of good quality, since road curbs were made of low quality concrete. This made the road stones unaesthetic, and they also did not meet the performance requirements for them.
The road border has long been an integral part of the roadway. When purchasing paving slabs, it must be remembered that the curb stones must be designed in the same style. In addition, it must be remembered that this road element serves not only to restrict the movement of vehicles, but also to protect the tiles, and also prevents gravel and sand from entering the nearby lawn. Therefore, a road curb of good quality serves as a delimiter between the sidewalk and the roadway, and therefore is a guarantee of convenience and safety.
Modern manufacturers produce high quality road curbs and the latest technology. The most demanded technology is vibrocompression,because this process can provide an optimal ratio of cost and performance, such as aesthetics and durability. You can also change the color of the mixture by adding the necessary coloring pigments.
The curb is laid using special equipment, but it also requires crushed stone, concrete and sand. Only after laying these auxiliary materials, you can start laying out the tiles, and hence the paving stone. It is the quality of these manipulations that will further affect the durability.
The need to use a road curb while paving a sidewalk has been proven by many examples. The functional load of this road element also includes the removal of water, both melt and rain, from the gaps between the tiles. Therefore, it is strongly advised to apply such framing of surfaces.
The Institute for the Construction of Prefabricated Urban Roads has issued a document that has been in force since 1996, in which the universal phrase “side stone” is used. However, it means the same border. The name "curb" is also common among the people.
The curbs, which in themselves are a kind of road markings, can also be applied with color markings corresponding to GOST on “The side surfaces of the curbs and its top.”
Curbs can not only mark the boundary between the roadway and the sidewalk, but also the so-called "safety islands" or "guidesislands.” Safety islands must be at least 10 cm high and level with the main surface of the pavement. However, in modern construction, it is allowed to lay a curb below this value to give an aesthetic appearance to the streets of the city.
