This allows the operator to max- imize uptime. Dynapac Seismic increases productivity with top-qual- ity results in the shortest amount of time. Dynapac Compaction Meter and Dyn@Lyzer displays the compaction results in easy to un- derstand graphics and eliminates any wasted time on unnecessary passes that are often made “just to be on the safe side”. By using Dynapac’s tools, you can avoid needless wear and tear and secure Dynapac’s great second hand value. A WINNING TRACK Dynapac’s first step in letting a machine automatically decide com- paction parameters was the introduction of Active Bouncing Control. If the compaction energy returns to the machine with the possibility of causing damage, vibration is actively shut off. This technology prevents unnecessary bouncing which saves the machine from downtime and secures a high second-hand value. With Dynapac Seismic, we continue to stay on our winning track of technology by automatically controlling the frequency to get perfect compaction.

It will be a standard feature for CA1500-6500 rollers together with the Dynapac Compaction Meter. Dynapac Seismic does it differently. Since the drum and the soil act as one dynamic system, several With the frequency automatically optimized at all times, Dynapac benefits can be found from the system’s natural Seismic will reduce fuel consumption, eliminate any frequency. At the natural frequency, the drum unnecessary wear and tear and even reduce the number of passes required to amplitude is enhanced significantly, since energy is reach the optimum compaction. automatically fed to the system at exactly the right Let the machine feel the soil time. This, in turn, maximizes the contact force be- and cooperate with it! tween the drum and the ground, yielding maximized compaction and energy efficiency. The best compaction parameters guarantee an optimal output. A machine that can determine soil characteristics and then automatically interact with them, will make the world of difference in com- paction results. Let the machine feel the soil and cooperate with it.

For many years, the soil and the drum were considered to be two separate systems. Thanks to Dynapac’s engineering team, they were able to recognize that the soil and drum actually work together as one system. This finding opened the door for the development of the Dynapac Seismic system. All drum and soil combinations have their own unique natural frequencies. Dynapac Seismic automatically detects the frequency of the soil character- istics, works together with it, and applies the correct amount of energy exactly when required.

In a world where environmental standards are constantly changing, asphalt producers can survive – and even thrive – with the help of a plant retrofit. A retrofit upgrades an old plant, so it meets new environmental standards – at a fraction of the cost of a new purchase. All projects are managed by the Ammann Retrofit Centre in Austria, which relies on proven processes and experienced technicians to troubleshoot any issues and ensure superior results. What can you get with a retrofit from Ammann? • Increased RAP utilisation • An electrically heated bitumen tank system that is so cost effective it pays for itself in a few years • Noise levels that are reduced up to 20 dB without an impact on daily production • An ability to use low-temperature mixes that reduce fuel usage and emissions Contact us to arrange a free analysis to learn the best opportunities for cost-effective, environmental improvements at your plant.
