One of the most exciting innovations in compaction is the exclusive SEISMIC on asphalt technology for tandem rollers from Dynapac North America . They’re one of the most longstanding names in compaction and this revolutionary tech has the ability to read the natural vibrational frequency in the asphalt, and attune the impact rate and the intensity to optimize compaction, fuel usage, and operator comfort. Now standard on all large tandem rollers, including the all new CC7000VI, the LARGEST breakdown roller on the market.

Andreas, thanks for having us at your booth here. I'm really interested to understand what seismic technology is and how it benefits contractors out there compacting asphalt. But I'm looking at this and wondering, how is this going to help me understand that?
Andreas Persson 0:16
Yeah, it's a good question. If we're looking at a conventional roller we create vibrations by spinning these eccentric weights inside our drums. Many people tend to believe that the higher frequency we use, the better compaction result we get. Is that not true. That is not true.

So we're losing energy Correct. There's a loss of energy not making it down to where we need it correct?
Andreas Persson 0:42
And if we let seismic do its job, it's going to look something like this. Oh, wow, we noticed two things, right? Yes, immediately, I'm consuming less energy up here, but I get more out in ground.

It's not about using more power, it's about more of that power getting to where it needs to go exactly.

We do see fuel savings, or energy savings, of around 25% for big machines like this. For big machines like this, seismic is actually included in all our heavy tandems. It's fully automatic. It's business as usual for the operator, there are no knobs to turn, no nothing new to learn, nothing new to learn.

How does the drum know how to change the frequency? How does it How does it know like, oh, this would be the best frequency for this situation.
Andreas Persson 1:36
So the machine is able to calculate that natural frequency, and it will do that five times every second, and it will adjust accordingly. It will adjust the frequency to match that natural movement of the asphalt or the ground you.
