Paving for two lanes, each measuring 13 m
A Vögele paver and Hamm rollers deliver first-class results in the construction of the Ningpan Expressway
A well-coordinated team performs impressively with top-quality results and high efficiency.
In order to build the new Ningpan-Panzhihua Expressway, the construction company undertaking the work opted for the powerful combination of the Vögele SUPER 3000-3i, the Hamm HC 228 D compactor and the Hamm HD 0128V tandem roller – with impressive results: The high quality of paving and the excellent compaction power demonstrate that the machines are the perfect choice for building contractors who attach great importance to excellent quality.
As the foundation of the road, the base course is crucial to its overall quality – it improves the load distribution and therefore increases the longevity of the asphalt surface course. Compaction plays a key role in this: It ensures that the road surface is sufficiently stable and durable to withstand a constant flow of traffic and the effects of natural forces.

Test results confirm the consistently high compaction quality
The construction company made use of different rollers when paving both the ballast base course and the hydraulically bound base course. However, the high compaction quality was primarily achieved thanks to the outstanding compaction performance of the HC 228 D. The evenness of the carriageway was significantly improved. This meant that, even on the day of the first measurement and three days later for the subsequent measurement, ≥96% of the required compaction values were met. What's more, for the hydraulically bound base course, this figure was as high as ≥97%. After the total compaction was completed, the degree of compaction of both layers, which were 36 cm thick in total, only showed a deviation of 0.3%.
Vögele SUPER 3000-3i: Maximum paving width, high paving capacity
The Vögele SUPER 3000-3i is the largest paver in the range and designed for paving very large widths of up to 18 m. The entire width of the road can be paved in a single working gear. This high continuous operation is made possible by the high-performance Cummins engine with a maximum power of 354 kW and a paving capacity of 1800 t/h.
The innovative material conveying concept enables a high conveying capacity, an ideal material flow and an optimal distribution of mixed material for different layers. A special feature is that the height of the rear part of the chassis, including the conveyor belt and spreading auger, can be continuously adjusted at the touch of a button. This means that the material is always transferred onto the spreading auger from above, in other words from the ideal discharge point.
Another highlight is that the Vögele SUPER 3000-3i has the option of hydraulically adjusting the tamper stroke for varying layer thicknesses. All it takes is the touch of a button – this speeds up the work process and ensures high-quality compaction results.
Hamm HC 228 D: Impressive compaction parameters
The HC 228 D belongs to the next generation of fully hydraulic compactors from Hamm. Its weight of 22 t is ideally distributed between the front and rear wheels – giving the compactor a higher compaction power than comparable machines in this weight class and playing a key role in achieving the required compaction value.
In addition, the roller is equipped with the intelligent HAMMTRONIC machine management system. Among other functions, the system enables the compaction speed to be pre-set with precision and prevents bulge formation thanks to smooth acceleration and braking. Measurements taken at different points in the new road have shown that the degree of compaction only varies by 1% – evidence that the new functions significantly improve the compaction quality.
You can find out more about the HAMMTRONIC control system and the particularly economic and energy-efficient Eco-Mode in the following video.
"The machine looks great and is extremely easy to operate. The intelligent speed control works very well and means that you no longer have to control the speed by feel."

High customer satisfaction
Both machine operators and project managers were impressed by the machines used. "The new Hamm compactors of the HC series are powerful, efficient, intelligent and easy to operate. They're ideally suited for soil stabilisation, earthworks and compacting materials of different thicknesses. They also save fuel costs and ensure efficient construction work. The Vögele pavers deliver excellent results with respect to evenness and compaction – both for asphalt paving and when producing a hydraulically bound base course. The two machines are the perfect pairing for achieving a high construction quality."
