What is an Asphalt Roller
The early roller used for asphalt was a hand roller operated by men, the horse drawn roller was also used to compact and roll the asphalt, and they were a single drum unit.
When the steam roller was introduced, many had three drums, two at the rear that drove or moved the roller and one smaller drum in the front that was used to steer the roller.
With the development of gas and diesel powered rollers, the steam rollers were used less because you would not have to take the long time it took to heat the water in the boiler to make steam to operate the roller.
Next came the hydraulic drive rollers with all hydraulic systems, today most all model asphalt rollers are self-propelled, all have steel drums, generally one of the drums is used to drive the roller.
The asphalt roller generally used for asphalt compaction is a smooth two drum or double drum vibrating roller, this compaction seals the asphalt or blacktop after the final finish layer of asphalt has been laid.
When additional compaction is needed the vibrating roller drums are used for a better compacting force.
Asphalt double drum finish rollers can be used as a static roller or vibrating roller, depends on the asphalt thickness and how warm the material at the time of compaction.
Asphalt rollers are all equipped with on-board water tanks for water lubrication of the steel drums surface, this is done with a sprinkler system and it prevents hot asphalt from sticking to the roller drums.
The asphalt roller is made in many sizes from the small self-propelled walk behind, to small ride on units to hand rollers all used to compact and finish asphalt after it is placed on the work area surface.
