A Solid Foundation for Reliable Infrastructure: The Crucial Role of Vibro Rollers in Toll Road Projects

Infrastructure development, particularly toll roads, is what keeps a country’s economy moving forward. Seamless connectivity not only speeds up the delivery of products and services, but it also sets the stage for regional growth and a better quality of life. The quality and endurance of these toll roads are not up for debate. The most crucial part of building them is compaction, which is what makes them successful. Without the right amount of compaction, road infrastructure can deteriorate too quickly, resulting in higher maintenance costs and, more importantly, increased safety risks for road users.

The vibro roller, also known as a tandem vibratory roller, plays a crucial role in this process. This huge machinery is made to compact both dirt and asphalt layers evenly and effectively. Its mechanism combines the static pressure of its weight with high-frequency vibrations to efficiently minimize air voids between material particles. This process boosts the density and strength of the foundation layer and prevents water infiltration that could weaken the structure from below. The speed and accuracy are excellent.

For large projects, such as toll roads, vibro rollers are more effective than regular static rollers.

Three Great Solutions: Choosing the Right Bomag Vibro Roller for Your Project Size

Each toll road construction project is distinct in its scale, challenges, and specific requirements. Knowing this, United Tractors, through Bomag, offers a variety of vibro rollers that can fulfill a wide range of needs. The following three models, the Bomag BW 151 AD-50, BW 161 AD-4, and BW 203 AD-4, exemplify German engineering. They can be used for a wide range of projects, from repairing roads to constructing large-scale infrastructure.

Bomag BW 151 AD-50: The Best Mix of Efficiency and Flexibility

The Bomag BW 151 AD-50 is marketed as the most flexible and practical option, perfect for a variety of road-building and repair tasks that require high accuracy and manageable costs. This machine has a working width of 1,680 mm, an operational weight of 7.6 tonnes (7,600 kg), and a 74.2 HP engine. It is the optimum blend of power and speed.

The best feature of the BW 151 AD-50 is that it can be configured to meet the specific needs of a particular project. This makes it a sensible choice for contractors who undertake a wide range of work.

• Ecomode makes your fuel last longer. One of the most significant challenges of operating heavy equipment is the high cost of fuel. The BW 151 AD-50 features a great Ecomode option that addresses this issue. This mechanism intelligently adjusts the engine speed to match the workload, saving up to 30% of gasoline. This feature also reduces noise levels and automatically turns off the engine when it’s not in use, thereby lowering daily operating costs.
• The Most Advanced Compaction Flexibility: Bomag knows that not all asphalt layers are the same. The BW 151 AD-50 features a “toolki” of compaction technologies that can be customized to meet your specific needs. This isn’t a “one-size-fits-all” strategy; instead, you can work with United Tractors to develop a solution that suits your business. Three possible vibration systems represent a distinctive Bomag advantage:
  • Double Vibration: This is the conventional dual vibration system that achieves deep, even compaction, making it ideal for most asphalt layer jobs.
  • TanGO (Tangential Oscillation): A groundbreaking new technology for delicate areas. This oscillation method offers “gentle compaction,” meaning the drum always remains in contact with the surface. This makes it great for compacting on bridges, thin layers, or near structures without the risk of damaging the structure or aggregate.
  • Asphalt Manager: An innovative system that automatically checks how stiff the material is and changes the vibration energy in real time. This ensures that every part of the road receives the correct amount of compaction, preventing over-compaction and resulting in a flawless surface.
• Quick and easy upkeep: In every undertaking, time equals money. The BW 151 AD-50 is designed so that all of its service points and engine parts are easily accessible from the ground. This significantly reduces the time required for daily maintenance and periodic repairs, allowing the machine to operate for more hours on site.

Bomag BW 161 AD-4: Great for Large Projects That Need a Lot of Work

The Bomag BW 161 AD-4 becomes a better option when the project is larger and the need for it to be completed faster becomes more pressing. This machine is a “workhorse” that is highly reliable for compacting all asphalt layers on toll road projects, as well as suitable for light soil compaction work, such as base and sub-base courses. The BW 161 AD-4 has a working width of 1,680 mm, a 10-ton operating weight, and a 99 HP engine. It has the power and efficiency needed for big jobs.

This device delivers substantial power, yet its design stands out by prioritizing both the end result and the operator’s experience.

• Deep Compaction Power: The BW 161 AD-4 can achieve the correct density with fewer passes due to its 10-tonne weight. This means that the project timetable will move much faster, whether you’re working on the foundation layers or the final wearing course.
• Premium Operator Comfort: United Tractors and Bomag recognize that the operator is the most critical person on site; therefore, they ensure the operator is comfortable so they can work at their best. The person who operates a machine has a significant impact on its productivity. The BW 161 AD-4 features a very comfortable operator’s station, complete with two steering wheels on the left and right sides, and a seat that slides to the side. This design is not only comfortable; it also enhances productivity. During long shifts, a pleasant and less tired operator is more focused, more productive, and more aware of safety.
• Intelligent Compaction Technology: The BW 161 AD-4 can be fitted with optional Bomag Economiser and Bomag Compaction Management (BCM) technology to make sure that every pass counts. These devices provide the operator with real-time data on the compaction process, enabling them to work efficiently and avoid costly rework due to over- or under-compaction.
• Easy to Maintain: Like its predecessors, this model is also easy to maintain. This large machinery can continue to operate with minimal downtime because all its parts are easily accessible. This keeps the project moving smoothly.

Bomag BW 203 AD-4: Maximum Reach and Power for the Largest Infrastructure Projects

For the most ambitious and demanding infrastructure projects, such as inter-island toll roads or airport runways, uncompromising solutions are essential. The Bomag BW 203 AD-4 is the answer.
