A road roller is a type of heavy-duty construction machinery widely used in roads, construction and other engineering projects to compact various materials to ensure structural stability and
durability. There are various types of road rollers, each with its own specific uses and advantages.
Static rollers: rely on their own weight for compaction and are used for compaction of various soil and asphalt concrete pavement layers. They are divided into bare wheel rollers, tire rollers, etc. .
Vibratory rollers: compaction of soil is carried out by the impact force generated by high-frequency vibration of vibratory wheels, which can improve the compaction effect and efficiency. They can
be driven by single or double steel wheels and are suitable for compaction of asphalt pavement and various soils.
Tire rollers: use special pneumatic tires for compaction, with the advantage of flexible compaction, suitable for compaction of asphalt concrete, sand and gravel mixture and other materials .
Impact roller: with the features of high pressure, deep impact depth and high construction efficiency, it is suitable for the foundation compaction of large-scale projects such as high-grade highways,
high-speed railroads, reservoirs and dams.
Drag type vibratory roller: it is suitable for the construction of modern highways, airports, embankment filling and other engineering construction, and can effectively compact all kinds of soil and
rock filling.
The following factors should be considered when choosing a suitable roller:
Soil structure: different types of rollers are suitable for compaction of different soil structures.
Construction efficiency requirements: the construction efficiency of vibratory rollers is usually higher than that of static rollers.
Construction process: Different construction processes may require different types of rollers.
Tonnage selection: The tonnage of the roller affects its compaction capacity and efficiency, and large tonnage rollers are suitable for high-grade road construction.
Manufacturer's technical level and service quality: choose a well-known brand and a manufacturer with good after-sales service.
The final choice of roller should be decided according to the specific project requirements, construction conditions and budget.
