What are the important roles of road rollers in engineering construction?

The road roller has a small operating radius and can operate in a smaller area, and is suitable for trench backfilling; it is equipped with a brand-name diesel engine, with superior performance and easy start-up; it adopts international brand hydraulic components, stepless speed change, forward and backward travel, and easy reversal; the diesel engine is started electrically, The vibration of the whole machine is controlled by electromagnetic clutch, making the operation simpler and more convenient; the luxurious seat is installed, which is easy to adjust and comfortable to work; the surface is spray-painted, beautiful and elegant, and is rust-proof and corrosion-resistant. Roads are subject to erosion and weathering by natural forces all year round, such as heavy rain, wind and sand, sun, floods, ice and snow, wheel wear and impact, etc. These damages and wear, both large and small, are effortless in front of the roller. Rollers can repair tight areas promptly, easily and quickly, thereby extending the life of the road. Flexible and convenient, the effect is better. The roller adopts a new design concept and can achieve good rolling effects in a small area; it is easy to transport. Compared with large rollers, small rollers are more efficient in transportation, handling, driving, operation, etc. The process is more convenient; small rollers play an important role in engineering construction. The purpose of compaction by rollers is to eliminate gaps in the soil, reduce permeability, reduce soil softening and expansion caused by water infiltration, and keep the soil in a stable state. Stabilizes embankment slope and maintains sufficient strength on fill to support loads resulting from traffic. Reduce the amount of filler settlement under pressure. In domestic railway and highway construction, subgrade subsidence is mostly caused by insufficient compaction machinery or poor compaction quality. Examples are not uncommon, and these have resulted in rework and great waste. At each friend's place, some roads are built and then rolled over with a small roller. In recent years, people have gained a new understanding of the importance of compaction work in practice. As far as road construction is concerned, poor road quality will reduce the service life of vehicles, and vehicles will have to drive at low speeds to adapt to road conditions, thereby increasing transportation time; at the same time, it will increase road maintenance costs. There are many reasons for poor pavement quality, poor compaction quality being the most important. Focusing on the overall situation, making careful calculations, and increasing investment in compaction operations will improve the economic and social benefits of the project. Road rollers are mainly suitable for working environments such as channels, ditches, underground, trimming, backfilling, and compaction. Not all are created equal. Therefore, before purchasing a small roller, it is necessary to have a relatively accurate positioning of the construction requirements and environment of the project, so that it can be targeted and will not cause idleness and waste of resources. The compaction operation of the road machine is an important process in the foundation construction of many construction projects, which directly affects the quality and service life of the project. Compaction machinery should play an important role in construction projects.
