Introduction To Road Roller Types & Their Suitability For Working Conditions

Road roller is widely used in the fill compaction operation of high-grade highway, railway, airport runway, and other large-scale engineering projects, which can crush sandy, semi-viscous and viscous soil, roadbed stabilised soil and asphalt concrete pavement layer. Road rollers are mainly divided into vibratory rollers, hydraulic rollers, pneumatic tyre road roller and so on. This article will introduce you to a variety of road rollers, so that you can choose the right road roller according to the working conditions.

 

1. Pneumatic Tyre Road Roller

 

Pneumatic tyre road roller is a kind of engineering machinery widely used in asphalt concrete surface construction. This kind of road roller carries out compaction operation on the road through its pneumatic tyres, generally 3 to 5 front wheels and 4 to 6 rear wheels, and the grounding pressure can be adjusted by changing the inflation pressure, and the pressure adjustment range is 0.11 to 1.05 MPa. This design makes the pneumatic tyre road roller produce kneading effect during the compaction process, so that the particles of the compaction layer are embedded without destroying each other, so as to realise the effect of uniform densification.

 

 

2. Vibratory Rollers

 

Vibratory rollers use their steel wheels to vibrate, and the vibration action improves the compactness of the soil or asphalt, as well as the load-bearing capacity and durability of the road. Vibratory rollers are mainly used on roads, motorways, airport runways and large yards. Its advantages include the ability to achieve high compaction results, high speed, and suitability for various terrains.

 

 

3. Double Drum Vibratory Roller

 

Double drum vibratory roller is mainly used in construction stage, asphalt pavement, cement pavement and other occasions, with good stability and smoothness, can achieve high construction quality, but compared with other rollers cost is a little higher.

 

 

4. Fully Hydraulic Road Rollers

 

Fully hydraulic road rollers, with advanced hydraulic technology, are able to pave roads and compact the ground efficiently and quickly. Its function is to compact the road or ground through the drive of hydraulic system to make it flat and firm. It performs well in some road compaction work with high quality requirements. It is mainly suitable for cohesive and non-cohesive materials, such as asphalt concrete, gravel mix, various kinds of stabilised soil and crushed cement concretes.

 

 

There are many types of road rollers, TRUCKMAN as a professional construction machinery experts can recommend the right roller for different applications, which can improve the quality of the project and construction efficiency while reducing the purchase and maintenance costs.
