The energy and fuel costs, but also the increasing requirements to reduce CO2 emissions pose huge challenges for the entire construction industry.
Solutions to reduce fuel consumption on the construction site are in increasing demand. If this is also linked to quality control and automatic documentation, there are many benefits.
If you look at an average asphalt roller with a fuel consumption of 15 liters / h, this results in a fuel consumption of 14,400 liters / year with an operating time of 120 days and 8 hours per day, which causes costs of EUR 28,800 at a current price of EUR 2 / liter.
Considering an average speed of the roller during compaction of 3,5 km / h, with an average width of the roller of 1.600 mm, there is an area of approx. 5,3 million m² of asphalt pavement that one roller can compact per year. With 4 passes for optimal compaction, it is only 1.32 million m², which causes costs of EUR 115,200. With an average of 4,5 passes per position, because the driver does not know where he has already compacted due to the lack of digitization, this area is reduced to 1,18 million m², which means an additional reduction of approx. 11% and the costs EUR 129.600. Fuel costs thus increase by EUR 14,400 compared to the optimal number of 4 crossings.
With Q Machines for rollers, the roller driver receives a visualization of the compaction runs that have already been carried out. Over- or under-compaction can thus be avoided. The system works across machines and machine type independently, it is ensured that only the required number of passes is carried out on the entire construction site - regardless of the roller manufacturer. As a result, not only the number of passes is optimized, but fuel consumption is also significantly reduced. The automatic documentation as proof of the high-quality compaction is another positive effect. An investment that not only pays off quickly, but also contributes to sustainable road construction.
