A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion. SA mining and operator training institute offers the training for this course roller compactor. The course is for R4500 for 10 days, the course comprises of theory and practicals Road rollers use the weight of the vehicle to compress the surface being rolled (static) or use mechanical advantage (vibrating). Initial compaction of the substrate on a road project is done using a padfoot or b'"'sheep's footb'"' drum roller, which achieves higher compaction density due to the pads having less surface area. On large freeways, a four-wheel compactor with padfoot drum and a blade, such as a Caterpillar 815/825 series machine, would be used due to its high weight, speed, and the powerful pushing force to spread bulk material. On regional roads, a smaller single padfoot drum machine may be used. The next machine is usually a single smooth drum compactor that compacts the high spots down until the soil is smooth. This is usually done in combination with a motor grader to obtain a level surface. Sometimes at this stage a pneumatic tyre roller is used. These rollers feature two rows (front and back) of pneumatic tyres that overlap, and the flexibility of the tyres provides a kneading action that seals the surface and with some vertical movement of the wheels, enables the roller to operate effectively on uneven ground. Once the soil base is flat the pad drum compactor is no longer used on the road surface. The next course (road base) is compacted using a smooth single drum, smooth tandem roller, or pneumatic tyre roller in combination with a grader and a water truck to achieve the desired flat surface with the correct moisture content for optimum compaction. Once the road base is compacted, the smooth single drum compactor is no longer used on the road surface (there is an exception if the single drum has special flat-wide-base tyres on the machine). The final wear course of asphalt concrete (known as asphalt or blacktop in North America, or macadam in England[citation needed]) is laid using a paver and compacted using a tandem smooth drum roller, a three-point roller or a pneumatic tyre roller. Three point rollers on asphalt were once common and are still used, but tandem vibrating rollers are the usual choice now. The pneumatic tyre roller's kneading action is the final roller to seal the surface. Rollers are also used in landfill compaction. Such compactors typically have padfoot drums, and do not achieve a smooth surface. The pads aid in compression, due to the smaller area contacting the ground.

It is ordered on demand from our supplier and is usually dispatched within 7 - 11 working days For thousands of years prior to Henry Hudson's voyage, the Hudson River was a vital commercial and strategic route for the indigenous peoples who settled near its banks. The river's importance continued for centuries afterward, linking the great trading center of Manhattan with remote places upstate and beyond. In Revolutionary times, the successful struggle for the Hudson was key to American victory over the power of the British military. The Hudson River railroad succeeded earlier modes of transportation in the Hudson Valley--the river sloop, the Albany Post Road, the steamboat, and the Erie Canal. The Hudson Line was both an early product of America's industrial age and a catalyst for the intense and complex developments of that age. The advent of photography coincided with the inauguration of the Hudson River railroad, and American photographers were on-hand to witness and record the progress of commerce and community in the villages, towns, and cities along the Hudson River Line.
