Different types of vibratory roller used for soil compaction

A vibratory roller is a compactor having a drum used to densify soil, asphalt or other materials through the application of combined static and dynamic forces to increase the load-bearing capacity of the surface. Vibratory rollers can fully cover the area underneath the wheel. It’s more efficient compared to other road roller types when it comes to compacting. The vibration of the roller can arrange the particles and exerts direct pressure on the specific layer. When the vibratory roller is in reverse, the vibration is briefly turned off to avoid disturbing the compacted area. This roller is best used to reduce air voids and for densifying granular soil.

There are different types of vibratory rollers used in compaction which are explained below.

Different types of vibratory rollers

 Towed Vibratory Roller:

A modern towed vibratory roller is exclusively developed for the compaction of earthworks; frequency, amplitude and vibrating mass were determined accordingly. The steel frame with its high ground clearance together with the transversely arranged diesel engine allows compaction work on slopes of up to 40 degrees. High reliability is achieved by the oscillation free mounted vibration drive. The machines come with – Electric starter, Electric remote control for vibration, Acoustic engine monitoring for oil pressure, V-belt, generator, Adjustable scraper Fuel gauge, Operating hour meter and Dry air cleaner.

Self Propelled Roller

Self propelled roller is ideal for the compaction of ditches and underlayments for the construction of foundations, streets and parking lots. Modern machines show its strengths especially in cohesive soils, since the kickstand, together with the high centrifugal force adjustable, the drum offers the best compaction results. The drums are available in two different widths. The remote control works with technology by infrared, which offers a high degree of security: the team stops as soon as the user loses visual contact. Latest models come with ergonomic driver seat for perfect all-round visibility, clear information display, excellent climbing ability via a self-locking differential, 3-point swivel joint for optimum driving comfort and hydrostatic steering,

Tandem Vibratory Roller

Tandem vibratory rollers are used primarily to compact paving materials, such as asphalt mixes and roller-compacted concrete. Modern machines feature two steel drums that vibrate via an internal, eccentric mechanism, which often can be adjusted to vary the frequency and amplitude of the vibratory action. Some tandem vibratory rollers are also equipped with satellite-navigation and proprietary software systems, continually report the degree of compaction and can map the job site’s compaction values for future reference. Modern models come with a 1.7 metric ton utility roller with 900 mm (35”) tandem vibratory drums. Modern tandem rollers weigh between 1680 kg and 9250 kg. Hybrid models also come with a free vibration system and articulation joint.

Combination Vibratory Roller

A combination roller is a double-treat of a machine with the compacting power of a vibratory roller and the asphalt finishing ability of a pneumatic roller. Together with its no-overhang frame and maneuverable design, it’s an ideal fit for walkways or bike paths, driveways, small parking lots, or any application where the efficiency of a single machine is preferred. Modern series of combination roller comes with a 2.6-ton model that comes standard with dual-frequency, auto vibration control, a pressurized water system and a no-hassle emissions solution. An inline drum with tapered edges and high curb clearance sits ahead of an oscillating articulation joint, providing precise and agile compaction capabilities in tight spaces. The drum delivers 10,566 lb. of centrifugal force and is assisted by standard features such as dual frequency and auto vibration stop, which (when activated) will turn off vibration in neutral to reduce the risk of divots. To reduce the risk of asphalt pickup, a pressurized water system with two-stage filtration provides reliable and constant flow to the drum and tires.

Walk – Behind Vibratory Roller

Walk-behind vibratory rollers are designed for the compaction of all sorts of soils as well as for the compaction of asphalt. Modern machines feature an optimal combination of centrifugal force, vibration frequency and static weight, resulting in excellent compaction effect. Travel of the machine is ensured by the hydrostatic system, consisting of a regulating hydraulic pump and a hydrometer. Travel speed and direction can be controlled infinitely by the travel control level, within the range from zero to maximal speed. The engine, hydraulic pump, hydraulic oil tank, centrifugal clutch and water tank of sprinkling are located at the base plate which is isolated to the vibrating part of the machine by four rubber mounts. It has a very compact design and offers great visibility to the operator at any angle which allows precise work near to walls and sidewalks.

Light Tandem Vibratory Roller

Light tandem vibratory rollers work perfectly against curbs and other obstructions and eliminate the need for special edge compaction efforts. Modern models come with double-drive and double-vibration is standard and helps deliver optimum compaction results. An electronic drive lever makes for smooth starting and stopping and is among the reasons the roller is popular with operators. Other operator benefits include a rubber-mounted platform that limits vibration and an intuitive instrument panel to help make even an inexperienced operator successful. Hybrid models feature vibration-insulated operator’s platforms with intuitive controls and a system for smooth starts and stops on asphalt. A smart compaction system and easy serviceability also fulfill customer needs. Light tandem vibratory rollers excel in tight spaces and maximize productivity when in the open. The rollers also are productive on soil, aggregates and asphalt

For vibratory rollers, manufacturers are now focusing on engine performance for fuel-efficiency. Fuel efficiency is a bonus that helps reduce your operating costs and has a direct impact on profitability. water-cooled and diesel-powered engines are therefore trending. Additionally, operator friendliness is a prime focus. A good design can help make operators comfortable and machine loading easy. One of the most important design benefits is the ease of use. Putting controls in easy-to-access locations and making displays visible and intuitive help operators is being focused.
