Curbs are equipped with projections on the side walls, to enable keeping the distance at the time of stacking. The joints between the curbs should be complemented by flexible masses of synthetic or leave blank. Should not be grouted with concrete curbs. It occurs transmission of loads between curbs resulting in cracks on the surface of the curb. The joints cause the concrete is also impossible to remove dirt on the surface of the curb. Other technical conditions set curbs should be implemented on the basis of the norm: "BN-64 / 8845-02 street curbs. Technical specifications set and acceptance."
Curbs light and heavy are manufactured in a single-layer technology with the addition of crushed aggregates: granite and basalt.
Curb road - a typical feature of road used to finish and protect surface made of cobblestones. Curbs are the apex surface made of cubes and help pave the sewer lines. Due to the fact that it is produced in several sizes can be adjusted to the amount and type of different surfaces.
Characteristic:
Curb road heavy - is in the dimension 100/20 cm, is 30 cm high, the monolayer structure
Curb traffic light - occurs in the dimension 100/15 cm, is 30 cm high, the monolayer structure
Curb road low - appears in the dimension 100/15 cm, is 25 cm high, the monolayer structure
Curb road entrance - is in the dimension 100/15, there is a height of 22/30 cm, the monolayer structure
