A road roller is a compactor type engineering vehicle, which is used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Also, road rollers are used in landfills and agriculture. The rolling process ensures that foundations are compacted thoroughly so the materials are compact, and do not come loose. Rollers are equipped with basic features such as diesel engine, canopy to protect the driver, drum(s), which can be a vibratory smooth drum or a static smooth drum, tires, a compaction meter to measure the level of compaction and a water system.
An analysis of the Use of road rollers
A road roller is a compaction vehicle used to compact soil, gravel, asphalt, crushed stone sub-base layer or some other site surface material. Rollers are most often used for road construction or for creating compact foundations for large areas although they can also be used in areas as diverse as on landfill sites or agricultural projects.The primary use for rollers is to crushing equipment, knead or vibrate loose materials by applying direct pressure. The rolling process is used to compact loosely bound foundation materials, so they remain compacted and do not come loose.
They are also known as smooth wheel loader rollers. These type of road rollers are mostly used for consolidating stone or other similar materials into flat land. They are believed to work best when you also use surface dressings to create an even smoother, flatter surface.
Vibratory Roller
On some machines, the drums may be filled with water on site to achieve the desired weight. When empty, the lighter machine is easier and cheaper to transport between work sites. On pneumatic tyre rollers the body may be ballasted with water or sand, or for extra compaction wet sand is used. Modern tyre rollers may be filled with steel ballast, which gives a more even balance for better compaction.
Additional compaction may be achieved by vibrating the roller drums, allowing a small, light machine to perform as well as a much heavier one. Vibration is typically produced by a free-spinning hydrostatic roller motor grader inside the drum to whose shaft an eccentric weight has been attached. Some rollers have a second weight that can be rotated relative to the main weight, to adjust the vibration amplitude and thus the compacting force.
Water lubrication may be provided to the drum surface from on-board “sprinkler tanks” to prevent hot asphalt sticking to the drum.
Hydraulic transmissions permit greater design flexibility. While early examples used direct mechanical drives, hydraulics reduce the number of moving parts exposed to contamination and allows the drum to be driven, providing extra traction on inclines.
