A compaction roller is an element of construction materials used for compact surfaces such as concrete, soil, gravel or tarmac during construction of foundations and roads. They are also used for compacting landfill, usually with a rolling basis in order to obtain a compacted on a smooth surface.
Roller compaction works by using the weight of a vehicle's surface, they are feasible to compress. In general, compaction is performed firstby a roller with tires filled with air, best suited to lightly, even non-land of a newly constructed road. The compaction roller drum with its sleek metal determines the smooth finish.
The compaction rolls may have been first drawn by horses and it is possible that they were used by the Romans were prolific builders of roads in the 2nd century BC.
In modern mechanized several reels were in use since the time of the invention of the steamroll around 1859 and remained in use in the United Kingdom nearly a century later when, in the year 1960, they were replaced by an internal combustion engine driven rollers. Parts of the existing M1 motorway have been constructed with the help of steam rollers.
The first motor coils were designed in the 1900s. Hamm AG, which is now part of Wirtgen GmbH, the first coils diesel produced in 1911. Hamm AG was founded in 1878 by the brothers Anton and Franz Hammwho both dealers, farm equipment building. In 1928, they took the bold step of abolishing all other product lines to focus solely on the compaction rolls.
The bet is won and Hamm AG went from strength to strength, consistently delivering innovative products to global demand, such as the development of a tandem, all roller compaction wheel drive in 1951.
When motorized rollers has been more widely used, the challenge was how to improve them. NovemberMay 1948, U.S. Patent 2,677,995 by the inventor WW Wood. The patent describes the use of vibration of the mass per meter output of the current generation of compaction rolls increase.
But it was a newly formed Swedish AB Vibro-Betong, which began in 1953 with the launch of the first vibratory roller. The compaction roller news was soon joined by similar products of competitors, including Bomag, vibrating roller BW60 which launched in 1957. ABVibro-Betong is still to this day but it is now known as the Dynapac and is part of the parent company of Atlas Copco since 2007.
The compaction roller is further improved and a wide range of products are now available, small plates and vibratory walk-behind trench roller through the mass ride-on rollers weighing 20 tons and cost more than $ 150,000 . landfill units may be even greater with a weight up to a massive 54 tonnes.
