When it comes to road rollers, it is necessary to give a brief introduction to the development of compaction technology. As early as ancient times, people used the hooves and feet of livestock to tread, knead, and compact the soil to treat the foundation of houses, compact dams and riverbanks. Before the mid-19th century, Western road engineering mainly relied on gravel paving, and compaction mainly relied on natural rolling by vehicles. It was not until the invention of the stone roller in 1858 that the development of gravel pavement was promoted, and the use of horse drawn rollers for compaction gradually emerged. This is the earliest prototype of road rollers. In 1860, steam rollers appeared in France, further promoting and improving the construction technology and quality of gravel pavement, accelerating progress. At the beginning of the 20th century, it was widely recognized that gravel pavement was the best pavement at that time and was promoted globally. The concept of compaction gradually became known to people, and road rollers also appeared on various road construction sites. In the mid-19th century, the invention of internal combustion engines brought great vitality to the development of compaction equipment. The first internal combustion engine driven roller was born in the early 20th century. Subsequently, the tire roller appeared, and the sheep foot roller and the light wheel roller were almost simultaneously produced. People have studied the compaction effect of the static roller and believe that increasing the weight of the roller can increase its line pressure, thereby improving the compaction effect. So, for a considerable period of time, people devoted themselves to developing large tonnage rollers, with the largest tire roller weighing over 200 tons. However, during this period, the changes in rollers were mainly reflected in improvements in power and appearance.
