Does speed matter when static rolling with a smooth drum roller?
Does speed matter when static rolling with a smooth drum roller?
(OP)
Everyone has an opinion. Mine woodland be that load is load no matter the speed.
Thanks for your input. Mitch

Check DynaPac, Caterpillar and Bomag.....all have efficiency curves for their equipment and will show the forward speed relationship.

Check your local DOT spec book and it will likely have a maximum rate of speed for the paver, the vibratory roller and the static roller. Obviously paver speed is for the full width of the pass. Review the roller train for maximum speed and width of each roller. I'll bet it takes 2 to 3 vibratory passes to get compaction. So a 6' drum roller on a 12' lane advances at BEST 1/4 the speed of the paver. This is why you'll typically see two vibratory rollers on production paving. While the static roller can help top off the density, I've not seen any contractor in the last 25 years use one for anything but taking out the roller marks.
CVG: I would tend to agree with you on staying away from means and methodology, but break out the vibratory roller spec's and see where high speed rolling "over-runs" the vibrators and creates ripples in the mat. We had a local contractor pull this stunt and ruin the ride quality of a new overlay about 15 years ago. They're no longer in the paving business. I think they actually met the density spec, but obviously violated the DOT speed limitations.
