What is a road roller?

Also called roller compactor. It uses the weight of the drum and the power of the engine to apply compaction force through vibration. The main purpose is to compact and stabilize surface materials on roads and construction sites. By increasing the density of the material, road rollers help reduce voids and achieve an even, level surface. This process creates durable and smooth roads, minimizes the risk of future subsidence or damage, and ensures the durability of infrastructure, whether it is on a highway, driveway, parking lot or large industrial site.

Road roller functions and components

Drum: The heavy cylindrical component responsible for the compaction process. Smooth rollers are used for asphalt and other smooth surfaces.

Engine: Provides the power needed to drive the drum and the machine itself, and is usually available in a variety of power levels to suit different project sizes.

Cab: The section where road roller is operated, designed to prioritize operator's comfort and view. Generally, it's equipped with cutting-edge control systems for effortless handling.

Water tank and spray system: These are incorporated to avert the adhesion of asphalt onto the drum and furnish lubrication, facilitating a seamless process of rolling.

Vibration system: An important feature that improves compaction efficiency (especially on double drum road rollers) by applying additional vibration forces to the surface material.

Understanding these components and their functions is essential to selecting the right road roller to meet your specific project needs, ensuring optimal efficiency and results in any construction environment.

Types of road rollers

Road rollers come in a variety of types, each designed for a specific application and suitable for different types of compaction projects. Here is a detailed description of the main types of road rollers from BISON:

Vibratory road rollers

Equipped with one or more vibrating drums, vibratory road rollers function through the oscillation during their operation. The combination of this vibration and road roller's weight substantially enhances impact of compaction.

Vibratory road rollers are especially effective for compaction of granular, mixed soils, and asphalt due to extra force derived from vibrations which work to lessen air gaps and bolster the density of substance.

Advantages:

• Capable of compacting a broad spectrum of materials effectively.

• Deep compaction can be achieved, suitable for thicker soil layers.

• Adjustable vibration amplitude and frequency to suit different materials and conditions.

Single drum road rollers

Single drum road rollers, consist of a broad cylindrical drum at the front and a pair of wheels at the back. The compaction of material is facilitated by drum's weight, and in certain cases, an integrated vibration mechanism may also play a role.

The primary use of single drum road roller is to compact soil, gravel and subgrades, during construction of roads and foundations. Excel in compacting vast areas and exhibit superior handling characteristics on irregular terrain.

Advantages:

• Highly maneuverable.

• Effective in deep compaction of the base layer.

• Typically robust and able to manage compact and coherent terrains efficiently.

• Adaptable to a wide range of landscapes.

Double drum road rollers

Also known as tandem road rollers, double drum road rollers are identifiable by their two steel drums positioned at the front and rear. Both drums can vibrate, providing additional compaction force.

Perfect for compressing asphalt to achieve a flat and uniform surface. They ensure even compaction across the entire drum width, making them ideal for road finishing.

Advantages:

• Ideal for creating a smooth, well-finished surface.

• Even pressure and compaction on both drums.

• Effective for areas with heavy traffic due to consistent surface quality.

Every kind of road roller serves a particular purpose, making each indispensable in numerous construction circumstances. Gaining insight into the distinctive attributes and uses of vibrating, single-drum, and double-drum road rollers can guide you in selecting the appropriate machinery for your construction requirements.
