    Road roller:

    What’s a road roller?

    Road rollers are machines which depending on its type, are used for pavement, compacting, and spreading materials (soil, gravel, lime, asphalt and etc.) on the ground.

    Road roller types:

    Rubber-wheeled road rollers:

    These road rollers are used for spreading asphalt. These wheels are often designed and manufactured into multiple axle rows.

    Two iron-wheeled road rollers:

    These road rollers are used for compacting asphalt for increased strength and higher life span after spreading process.

    Single metal-wheeled road rollers:

    They are available in automatic and tensional types.

    Automatic road rollers:

    They are designed with two wheels in back and a big metal wheel (drum) in front. Considering high power of machine, more pressure will be on surface to pummel rock, soil, lime and etc.

    Tensional road rollers:

    These road rollers must be attached to a tractor’s rear in order to operate. An engine is implanted for compacting process.

    Metallic roller (drum) in this machine are designed into two STD (smooth) and PDP (rough) types.

    Standard type of this road roller are commonly used for smoothing and compacting surfaces.

    For mauling and pummeling stone materials in subgrade and roads, rough type is used.

    Drum’s mechanism in one or two-wheeled road rollers are designed in a way that it could rotate and roll simultaneously and vibrate heavily by doing so which these vibrations are transferred to surface beneath road roller and therefore, compacting it.

    Cylindrical Rollers (manuel rollers):

    In small scale projects where there isn’t much space for big road rollers maneuver and presence, Manuel rollers are used which their mechanism is similar to bigger road rollers with only one difference which operators are required to use their own force to control and steer road roller.

    • With due attention to machine’s high power, more pressure will be applied to surface for compacting soil, rock, lime and etc.
    • Metallic roller (drum) of this machines are designed into two categories: STD (smooth) and PDP (rough)
    • These road rollers have two wheels in back and a big drum roller in front.

    Drum’s mechanism in one or two-wheeled road rollers are designed in a way that it could rotate and roll simultaneously and vibrate heavily by doing so which these vibrations are transferred to surface beneath road roller and therefore, compacting it. The process it called vibration.
