Roller manufacturer Hamm has introduced the Smart Compact Pro under the motto “Measure it right. Measure it now.”

For the first time, real-time density is being used as a decisive parameter for qualitative assessment and integrated into automated compaction. Smart Compact Pro makes a significant contribution to extending the service life of road surfaces and, in the long term, reduces construction and repair costs, as well as potential additional expenses for the contractor.

Automated compaction with Smart Compact

Despite advances in digitalisation, asphalt compaction has so far been heavily dependent on empirical data and the experience of the roller driver. Consistent double passes and the correct use of dynamic compaction were often dependent on the driver’s knowledge. Since 2022, the Smart Compact digital compaction assistant from Hamm has been simplifying the compaction process in asphalt construction by controlling the compaction modes and forces based on the selected layer type – base, binder or surface course – automatically and separately for both drums.

The system continuously monitors the asphalt’s physical properties, such as temperature and rigidity, as well as its complex cooling behaviour, to ensure homogeneous compaction by applying the optimum compaction energy and modes in each case. There is even the option of incorporating local weather data.

Smart Compact Pro with real-time density measurement: Higher quality, lower costs

Hamm is now expanding Smart Compact to incorporate an essential measured value – real-time asphalt density. Industry experts agree that it is the decisive parameter for qualitative assessment during the compaction process and will become the key indicator for rigorously meeting regulatory requirements and minimising financial deductions.

Smart Compact Pro closes this gap by integrating the new “Realtime Density Scan” sensor into the automated compaction process. It determines the asphalt density in real time by measuring the dielectric conductivity of the asphalt mix to be compacted, therefore forming the basis for the correlation with the asphalt density or the porosity. Both parameters are crucial for self-monitoring or control testing. With the help of real-time density, Smart Compact Pro is able to provide construction companies with a decisive advantage by accurately implementing regulatory requirements.

This can significantly reduce potential financial deductions due to inadequate quality in the construction work and also save costs for premature repairs. Using Smart Compact Pro also significantly reduces the costs for extracting drill cores.

In summary, the world-first integration of real-time density into automated compaction represents a significant step forward for asphalt compaction. Even inexperienced operators can achieve optimal compaction results with Smart Compact Pro, with no need for extensive prior knowledge. This offers a significant boost for construction companies in times of an increasing shortage of skilled workers.

At CONEXPO-CON/AGG, John Deere Power Systems debuted the latest additions to its Next Generation Engine (NGE) range, where they formed the cornerstone of a versatile lineup designed to meet the industry’s evolving demands

The upcoming JD5 and JD8 industrial engines will offer more flexible power solutions to meet the diverse needs of its OEM customers, reflecting the company’s commitment to customer choice and providing the right power for the right application. The JD5 and JD8 will enhance power options in key mid-range applications where power density and installation flexibility are critical.

The JD5 5.0L engine will offer an anticipated power range of 125–268 hp (93–200 kW), and the JD8, a 7.5L engine, will offer an anticipated power range of 250–389 hp (187–290 kW). They will be compatible with renewable diesel fuel and biodiesel blends.

The lead application for the JD8 is anticipated to be launched in 2029, followed by the JD5.

JDPS also showcased the latest in KREISEL Electric (KREISEL) batteries, an advanced battery technology designed to prioritise runtime, energy density, and seamless integration, as well as highlighting a versatile charging ecosystem to support the transition to electric, with the development of both stationary and mobile charging options with varying power outputs.

Speaking to African Review at CONEXPO-CON/AGG, David Wendt, account manager at John Deere Power Systems, underlined the company’s commitment to investing in diesel engine technology as part of a multiple-pathway approach which includes advancing next-generation diesel engines, enabling compatibility with renewable fuels, and integrating battery technology in applications where it delivers the most value — all supported by comprehensive aftermarket and customer support solutions. This strategy allows OEMs to leverage advanced diesel technology alongside emerging power solutions, providing the flexibility to thrive in an evolving landscape without compromising performance. There is no one size fits all solution.

“Over the past five years, we have introduced three new John Deere diesel engines in addition to the two we’re showcasing here,” said Wendt. “This marks a new era of power and an expanded displacement range for our engine lineup. It’s important for our customers to see John Deere’s continued commitment to investing in diesel technology.”

Wendt also highlighted a focus on serviceability and maintainability within the NGE engines. This is evidenced by extended service intervals and a design that prioritises accessible, cost-effective maintenance for common repair items — all aimed at reducing the customer’s total cost of ownership.

“What is important for customers, whether in Africa, the Middle East or anywhere around the world, is not only engine performance, but serviceability. This is something we are really focused on,” he stressed.

He explained that common design characteristics across its JD series mean that technicians are able to address issues and get machines back up and running faster. Often engines will have identical part numbers or common systems, which makes it much easier for technicians to service different engines.

“These engines were all designed to be power dense, to be electronically controlled, to meet emissions requirements and to be easy to service,” he said.

Wendt added that certain features have been designed into the NGE engines to help reduce maintenance and downtime, helping customers to keep their operations up and running. One of these is hydraulic valve lash adjustment, which allows for the elimination of a maintenance interval that usually takes place between 2,000 and 2,500 hours. It also allows for quiet operation, contributing to a better operator experience, and reduces wear and tear on the valve train, resulting in better durability and reliability. Additionally, the gear train has been moved from the front of the engine to the rear, which not only eliminates torque and torsion, but also allows for a belt-driven water pump at the front, eliminating the possibility of coolant entering the oil system should the pump fail.

“Ultimately, it is about keeping the customer’s overall experience at the forefront of everything we do,” he concluded.
