Modern-day compaction equipment is being integrated with advanced technologies. They are being used in soil to rearrange the particles and reduce the void ratio and increase soil density. The compaction of soil increases the shear strength and load-bearing capacity of the soil. Improper compaction of soil results in structural distress from excessive total settlements and differential settlements.
Manufacturers are focusing on coming out with compaction equipment models that are fuel-efficient and require minimal maintenance. With competition, intensifying suppliers are concentrating on coming out with machines that would ideally suit Indian working conditions. These machine models could be put through more work cycles. Performance and productivity maximisation remain the pivotal issues for compaction equipment manufacturers from their latest units. Deciding on the type of compaction equipment is mainly dependent upon the water content of the soil, the type of soil being compacted and the amount of compaction energy used. Apart from regular soil compression activity this equipment is being used in a multitude of activities starting from building roads to constructing industrial complexes. Modified drums and intelligent compaction are the new value-engineered add-ons that promise higher productivity at a lower operating cost. New features also encompass competitive features for superior performance, lower cost of operation, easy access for maintenance, reliability, and safety in operation when working on hilly terrains and gradients. Discussed below are different types of soil compaction equipment used across India in different projects.
Soil compaction equipments in India
Pneumatic tyred rollers with Optional Traction Control
Pneumatic rollers have become more popular with stiffer mixes since they can help you achieve compaction density. These types of rollers consist of tyres that provide better static penetration into the materials. The weight of the machines and air pressure of the tires can be adjusted to meet the specific pressure desired on a particular job. Pneumatic rollers now come with optional traction control that boosts productivity on tough terrain. The proven hydrodynamic propulsion system ensures productivity. The rollers provide the kneading and sealing effect for job sites increasing productivity on tough terrain. The pneumatic rollers perform on both aggregates and asphalt, offering flexibility with air pressure adjustment features. Ballast packages easily can be added or removed to ensure the most efficient machine and process are provided. can be used on several different projects such as subdivision streets, large parking lots, and driveways. Operators would find the machine easy to control as it is very user-friendly and easy to operate, it comes with a spacious cab. Everything can be easily managed by the operator through a control operation station. Pneumatic rollers have become more popular with stiffer mixes since they can help you achieve compaction density.

Soil compactors with Optimum compaction performance
The newer model comes with a drum width of 2140 mm and a high static linear load, the compactors can be used universally in inner-city projects, for compaction on motorways, airports and other large areas. The model ensures that maximum compaction force is always available, and vibration works immediately once the nominal frequency is activated. For the driver, the acceleration of the vibrating unit is imperceptible. The automatic vibration system ensures that the vibration is shut off as soon as the compactors stop moving. This prevents over-compaction and guarantees high-quality surfaces. The three-point articulation in the new compactors guarantees outstanding directional stability, impressive stability when negotiating curves, and a high level of safety against overturning. This means that the compactors deliver outstanding manoeuvrability and excellent compaction, even on uneven terrain. The models are driven by a robust, water-cooled 4-cylinder engine in accordance with CEV Stage IV. During compaction, the operator can choose between three preset engine speeds. If the driver selects the average speed, the machine operates in ECO mode. This mode reduces fuel consumption by up to 20%, as well as lowering CO2 and noise emissions. Yet, in spite of this, frequency and centrifugal force as well as full compaction power continue to be maintained. This is enabled thanks to the large-sized hydraulic components and a smart control system.
Tandem roller for asphalt compaction
Tandem Roller models are designed to fulfil the growing demand of road compaction. It is best suited for applications such as highway road shoulders, retaining the walls of flyovers, footpaths, trenches, service roads, industrial and residential columns, rural roads. This is a versatile roller as it can be used for both earth and asphalt compaction. With an amazing set of features, like great fuel efficiency, 10% higher productivity than any other, unique drum offset, free vibration system & articulation joint. The tandem roller is also equipped with the latest ‘Q’ built hydraulics. This compactor has an auto dust removal system and provides unmatched operator comfort which ultimately increases efficiency and maximise productivity. The model offers greater visibility for ease of operation and is equipped with an automatic water sprinkler system which minimises the effort. The cab platform is mounted on 4 viscous mounts, to isolate it from any vibrations and to make the operator feel comfortable even during high amplitude passes Similarly, the tandem roller comes with optional ROPS, large steps on the chassis for easy access to the seat, and with provision to lock the bonnet.
Single drum vibratory rollers for different lift depths and material types
Single-drum vibratory rollers models are designed for fast and consistent soil compaction on varying lift depths and material types. This is achieved with high centrifugal forces and standard dual amplitude and dual-frequency capabilities that allow the operator to dial in compaction performance to each lift. Both rollers operate at 154 horsepower and weigh in at 33,420 and 36,500 pounds, respectively, with centrifugal forces up to 73,063 and 74,861 pounds. Each model is also compatible with ACE force intelligent compaction technology to further ensure compaction quality, documentation and productivity. The models feature a low-center-of-gravity, as well as an axle-free design that provides constant power to the wheels and drum with an electronic self-adjusting torque control system.
Double drum vibratory rollers with Roll Over Protective Structures
The latest double drum asphalt roller range features everything from the most compact equipment for repair jobs to large machines for the biggest sites. Vibration dampened platforms, swivel seats for better visibility, logically sorted controls and Roll Over Protective Structures (ROPS) all contribute to the manoeuvrability, operator ergonomics and safety. The models are used primarily for small-scale compaction work such as pavements, cycle paths, small roads and small parking areas – places that need compaction but are difficult to reach with a larger roller. These small tandem rollers come with an operating mass of approximately 1.6 tons and drum widths of 800 to 1000 mm. With the large drum diameter and the drive motors connected in series, there is excellent accessibility and hill-climbing capability. Propulsion and vibration are standard on both drums. A spacious, vibration-damped operator platform and an ergonomically positioned step make these machines extremely operator-friendly.
Conclusion
Manufacturers are also focusing on coming out with machines that are fuel-efficient and require minimal maintenance, all adding to the good news for contractors. With competition, intensifying suppliers are concentrating on coming out with machines that would ideally suit Indian working conditions, where typically these machines would be put through more work cycles, as compared to the developed world.
