Multi wheel roller machines maximise the production of asphalt finishing and sealing, and can even be used for compacting dirt roads. Newer models are comfortable and easy to operate with ergonomic controls, sliding seats and steering assembly. These controls mean that the operator can focus on compacting the surface, or maintaining good visibility, rather than checking the controls or moving the seat to get a clear line of sight to the roller.
Of course, older machines aren't as equipped as newer models and may not have as much technology going for them, but they will still get the job done. Both new and older models have the same basic build, they consist of a heavily loaded wagon with a row of 4 or 6 closely spaced tyres. Generally, these are rubber tyres which provide a uniform pressure throughout the width of the roller. This is ideal for creating a smooth and even surface.
When looking at any multi wheel roller, it's important you look at the tyre pressure, area of contact and vehicle weight. The tyre pressure and area of contact will help you figure out how many passes of the machine you will need to reach maximum density and an overall smooth finish. Of course, the amount of passes you complete to reach maximum density will depend on the type of machine you choose, but generally a multi wheel roller can achieve this in 8 passes. This can be increased with the addition of steel sections on the tyres.
There are many benefits to using a multi wheel roller including their ability to achieve a more uniform degree of compaction when compared to steel rollers. Another benefit is the increased density that often cannot be achieved with a steel roller. These machines can also be used to remove surface cracks caused by previous compaction.
Whether you're in the market to buy or hire a multi wheel roller, it's important you know the scale of your project. These machines are an investment and are priced anywhere from $1,300 to $575,000, so make sure you speak to local dealers or sellers to find out the best option for your needs.
