The main purpose of road rollers is to roll the asphalt layer during road construction works. This special equipment is indispensable during the construction of highways, and that is why it occupies a special important place in the ranks of road-building equipment along with the order of renting a crane and backhoe loader.
According to the principle of operation, road rollers are divided into static and vibratory. The principle of operation of static rollers is to bind the massif, and with the help of the pressure exerted on it you can achieve a smooth surface of the road surface. Vibratory rollers work by artificial vibration, thereby compacting the road layers. There is a high demand on the market for road rollers with small dimensions, thanks to which it is possible to work in narrow passages next to walls and curbs. These rollers are essential for asphalting cycle paths, sidewalks and small areas. The vibrating mechanism ensures high quality compaction, and if the roller is used for patching, the vibration will give a strong bond between the new and old pavement. Road rollers have the following classification: asphalt, soil and sidewalk rollers.
The soil compactor restores the strength and density of soils that are laid in engineering structures, giving them proper stability, watertightness and bearing capacity. The quality of the work done is assessed by the ratio of the actual density to the maximum standard density of the soil, which is determined using the standard compaction method. The main purpose of asphalt rollers is layer-by-layer compaction of asphalt concrete mixture to give the necessary strength, flatness and water resistance, which are stipulated by technical specifications for airfield and highway asphalt concrete pavements.
Sidewalk rollers are mainly used in the repair and construction of highways, bicycle and pedestrian paths, shoulders, sidewalks, garden entrances, garages, landscaping, etc. Usually, when there is a question about a certain choice of a road roller for any type of work, it is necessary to pay attention to the following characteristics: the area of contact of rollers with the compacted material, weight, speed of compaction width, etc. Of importance is the material for which you are buying a road roller. For example, combination rollers with vibrating rollers or smooth rollers are usually used for asphalt.
