A self-propelled construction machine that uses iron rollers to compact soil and gravel. There are two types: the macadam type with two axles and three wheels, and the tandem type with two axles and two wheels or three axles and three wheels. Tire rollers, which have seven to eleven tires instead of iron wheels, are used for both roadbed compaction and finishing. Source : Heibonsha Encyclopedia About MyPedia Information |
