Reliability, durability and strength of roads to a large extent depend on the quality construction of the road surface. To facilitate this process, a special technique is used.
To compact, level, compact, soil or gravel, asphalt or concrete in the foundations, as well as road structures, a road roller is used. The scope of use of special construction equipment is quite extensive - it is industrial, hydraulic, road, urban, railway, airfield construction.

The principle of operation and the way of moving different equipment is different. There is a trailed and self-propelled technique, static and vibration. The road roller is equipped with specific working bodies.
It can be steel rigid rollers or
pneumatic tires. Rollers, in turn, are divided into smooth, trellised or with special cams on the surface.
The road roller compacts road building materials by rolling its working bodies. The machine, moving on the surface of the road, carries out the process of compaction of the pavement with its own mass. The asphalt road roller is indispensable for construction work in stadiums, for compacting sand and pebbles on roads, for laying asphalt and in small-sized construction.
To perform some types of work , a vibratory road roller is used, capable of periodically producing vibrations of working bodies. Such a machine is equipped with a hydrostatic transmission, hydraulics are controlled by an electrotechnical system.
For the full-fledged operation of vibration functions, the mechanism of the so-called crab course is involved.
Road rollers are endowed with excellent characteristics, they are reliable in operation. It should be noted that the self-weight of the unit has a certain value when it affects the material being sealed. Among the special construction equipment, there are combined road rollers with compacting bodies, which are characteristic for devices of various types.
Among the roller road rollers, which are pivotally mounted shoes on the rim of the roller, stand out lamellar, cam, ribbed and trellised types.
Lattice roller road rollers are characterized by the working surface of the roller rim in the form of a lattice, and in the cam rollers several rows of cams are rigidly fixed to the roller rim.
Asphalt laying, road construction works are carried out mainly on the latest foreign equipment. This is due to the high technical characteristics of this specialized road equipment, its convenience and maximum ease of management, pleasant appearance, appropriate equipment. This technique confirms high productivity and maximum efficiency when performing work on asphalt pavements, while compacting asphalt mixtures along walls.
