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, asph alt or concrete in 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 method of movement are different for different equipment. There are trailed and self-propelled equipment, static and vibration. The road roller is equipped with specific working bodies.

It can be rigid steel rollers or pneumatic tires. The rollers, in turn, are divided into smooth, lattice or with special cams on the surface.

Road roller compacts road building materials by rolling its working bodies. The machine, moving along the road surface, carries out the process of compacting the road surface of its ownmass. The asph alt road roller is indispensable for construction work at stadiums, for compacting sand and pebbles on roads, for laying asph alt and in small-sized construction.

To perform some types of work, a vibratory road roller is used, capable of periodically vibrating the working bodies. Such a machine is equipped with a hydrostatic transmission, hydraulic control is carried out using an electrical system.

For the full operation of the vibration functions, the mechanism of the so-called crab move is used.

Road rollers are endowed with excellent performance, they are reliable in operation. It should be noted that the own weight of the unit has a certain value when exposed to the compacted material. In a number of special construction equipment, there are combined road rollers with compacting bodies, which are typical for devices of various types.

Among roller road rollers, which are hinged shoes on the rim of the drum, there are plate, cam, ribbed and lattice types.

For lattice roller road rollers, the working surface of the drum rim is characteristic in the form of a lattice, and in cam rollers, several rows of cams are rigidly fixed on the drum rim.

Asph alt laying, road construction work is carried out mainly on the latest foreign equipment. This is due to the high technical characteristics of this road specialized equipment, its convenience and maximum simplicity.control, pleasant appearance, appropriate equipment. This technique confirms high performance and maximum efficiency when working on asph alt road surfaces, when compacting asph alt mixtures along walls.
