Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Road Roller shopping experience:
1. Compare - without doubt the biggest advantage that the Road Roller offers shoppers today is the ability to compare thousands of Road Roller at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Road Roller? Wrong! If the Road Roller is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Road Roller then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Road Roller? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Road Roller and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Road Roller wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Road Roller then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Road Roller site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Road Roller, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Road Roller, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
diesel road roller-powered roller
A
Road roller (sometimes called a
roller-compactor, or just
roller) is an
engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of
road and Foundation (architecture).
In many parts of the world, road rollers are still known colloquially as
steamroller, regardless of their method of propulsion. This typically only applies to the largest examples (used for road-making).
History
The first road rollers were
horse-drawn, and were probably just borrowed farm implements
(see roller (agricultural tool)).
Since the effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid 1800s. The first such vehicles were
steam rollers. Double-cylinder designs were preferred. Single-cylinder steam rollers were uncommon and unpopular, as the power impulses from the steam engine would produce slight waves in the road. Some road companies in the United states used steamrollers through the 1950s, and in the UK, some remained in commercial service until the early 1970s.
As internal combustion engine technology improved during the 20th century,
gasoline (petrol), and
diesel, powered rollers gradually replaced their steam-powered counterparts. The first internal-combustion powered road rollers were very similar to the steam rollers they replaced. They used similar mechanisms to transmit power from the engine to the wheels, typically large, exposed spur gears. Some companies did not like them in their infancy, as the engines of the era were typically hard to start. Virtually all road rollers in commercial use now use diesel power.
Uses
Road rollers work by using the weight of the vehicle to compress the surface being rolled. Initial compaction of the substrate is done using a
pneumatic-tyred roller, where instead of the single- or double-drum is replaced by two rows (front and back) of pneumatically filled tyres. The flexibility of the tyres, with a certain amount of vertical movement of the wheels, enables the roller to operate effectively on uneven ground. The finish is done using metal-drum rollers to ensure a smooth, even result.
Rollers are also used in landfill compaction. Such compactors typically have knobbed ('sheeps-foot') wheels and do not attempt to achieve a smooth surface. The knobs aid in compression due to a smaller surface area being in contact with the ground.
Configurations
The roller can be a simple drum with a handle that can be operated by one man, and weighs 100 pounds, all the way up to a massive ride-on road roller weighing 21
short tons (44,000 lb or 20
metric ton) and costing more than
U.S. Dollar150,000. A landfill unit can weigh 59 short tons (54 tonnes). On some machines the drums may be filled with water.
Roller Types
- Manual walk-behind
- Powered walk-behind (electric or diesel/gas powered)
- Trench roller (manual units or radio-frequency remote control)
- Ride-on
- Ride-on with knock-down bar
- Ride-on articulating-swivel
- Vibratory
- Pneumatic-tyre
- Tractor mounted and powered (this may be a 'one-off' – see gallery picture below)

Drum types
Drums come in various widths: 24-to-84 inches
- Single-drum sheeps/pad-foot (soil)
- Single-drum smooth (asphalt)
- Double-drum (duplex) sheeps/pad-foot (soil)
- Double-drum (duplex) smooth (asphalt)
- 3-wheel cleat with bulldozing blade (landfills)
Variations and features
- On some machines, the drums may be filled with water on site to achieve the desired vehicle weight. When not filled, the lighter machine is easier and cheaper to transport between worksites.
- Additional compaction may be achieved by vibrator (mechanical) the roller drums
- Water lubrication may be provided to the drum surface to avoid hot asphalt (for example) sticking to the drum
- Hydraulic transmission permits greater design flexibility (early examples were direct mechanical drive) and reduces the number of moving parts exposed to the dust and filth associated with construction sites
- Human-propelled rollers may only have a single roller drum
- Self-propelled rollers may have two drums, mounted one in front of the other (format known as 'duplex'), or three rolls, or just one, with the back rollers replaced with treaded pneumatic tyres for increased traction

Road rollers in popular culture
In fiction – as a character
Roley is one of the main vehicle characters in the children's books and TV series,
Bob the Builder. He is a green roller with a cab, enclosed power unit and no chimney, and so is obviously diesel-powered – nevertheless, his official title is
Roley the Steamroller. This is another example of why the use of '
steamroller', to describe a large modern road roller, still persists in the English language.
On film – as a weapon
Film-makers seem to like the finality of a roller of some kind squashing a human. In most cases, however, the roller is not actually steam-powered, even though it is usually referred to as such. In all of the following examples, the roller in question is
diesel-powered.
- In The Naked Gun, the villain is run over first by a bus, then a 'steam roller' and finally a marching band.
- In Who Framed Roger Rabbit the true identity of the villain is revealed after he is run over by a 'steam roller'.
- At the end of A Fish Called Wanda, Ken (Michael Palin) gets his revenge on Otto (Kevin Kline) at Heathrow Airport, in a scene involving a small diesel roller and some wet concrete.
- In Maximum Overdrive, a Little League player is killed by a "rebelling" 'steam roller'.
In fiction – as a weapon
In the Japanese manga
JoJo's Bizarre Adventure, the villain
Dio Brando attempts to finish off his rival Jotaro by dropping a road roller (sometimes translated as 'steam roller') on him from midair. This scene has also appeared in several
video games and has been popularized by the Flash movie "mudah.swf".
