Compaction EquipmentPavement Interactive
Steel wheel rollers are self-propelled compaction devices that use steel drums to compress the underlying HMA. They can have one two or even three drums although tandem (2 drum) rollers are most often used. The drums can be either static or vibratory and usually range from 86 to 215 cm (35 to 85 inches) in width and 50 to 150 cm (20 to 60
