A three ton roller is a ride on tandem machine with two vibrating drums, about four feet wide, and it is the class most driveways, car parks and patch repairs are compacted with. Hire runs roughly $250 to $400 a day. The figure describes operating weight with water aboard, which is worth knowing before you hook it to a trailer expecting three tons exactly.
What the weight figure is describing
Operating weight counts the machine, a full water tank and the operator, so a roller sold as three tons can weigh appreciably less empty and a little more in service. Vibration then multiplies the force the drum applies. That is why a three ton vibrating machine compacts more than a much heavier static one would.
The jobs this class is sized for
Domestic and commercial driveways, footpaths, small car parks, road patches and the granular base under all of them. It is small enough to work around kerbs and manholes and heavy enough to finish asphalt properly. Larger areas want a wider drum, and anything narrow or trapped wants a walk behind or a trench roller instead.
Water, mats and the towing weight
Drums are wetted from an onboard tank so hot asphalt does not lift, and the tank is part of what you tow. With machine, trailer and a full tank you are into a braked trailer and a heavy pickup, and the yard will ask what is pulling it. Check the water spray works before the truck leaves.
How many passes before it stops moving
Compaction comes from passing over a layer repeatedly until the drum stops sinking and the sound changes, not from one heavy run. Thin layers compact; thick ones move under the drum and rebound. Ask the yard what the machine's amplitude settings do, and keep the layers within what this size can reach through.
Questions people ask about 3 ton roller
Is a 3 ton roller enough for a driveway?
For a domestic driveway it is comfortably enough and often more machine than strictly needed. The limiting factor is usually access at the gate rather than weight, so measure the narrowest point before booking.
Do I need a special licence to tow one?
No special licence for most drivers, but the combined weight matters: machine plus trailer sits above what a light vehicle should pull, and brakes on the trailer are effectively required. Yards will deliver for a fee that often costs less than the trip.
Vibration on or off?
On for base and for asphalt while it is hot, off for the final passes and on anything brittle or near a structure. Vibration close to a wall, a pipe or a boundary can do damage the drum's weight alone would not, so switch it off and add passes.
