History and Development of Road Roller

As early as in ancient times, people used the hooves of herds to trample, knead and compact the soil to deal with the foundation of houses, compact dams and embankments, and before the middle of the 19th century, Western road projects used gravel Sub-paving is the main method, and the compaction mainly depends on the natural rolling of vehicles. It was not until the invention of the stone rolling machine in 1858, which promoted the development of gravel roads, that horse-drawn rollers were used for compaction work. This is the earliest In 1860, the steam roller appeared in France, which further promoted and improved the construction technology and quality of gravel pavement, and accelerated the progress. At the beginning of the 20th century, the world recognized that the gravel pavement was the best pavement at that time and was promoted all over the world. The concept of compaction gradually became known to people, and road rollers also appeared on various road construction sites. In the middle of the 19th century, the invention of the internal combustion engine It has brought great vitality to the development of compaction equipment. The first road roller powered by an internal combustion engine was born in the early 20th century. Then came tire rollers, sheep foot rollers and bare wheel rollers almost at the same time. People have studied the compaction effect of static rollers, and believe that increasing the weight of the roller can increase the line pressure of the roller, thereby improving the compaction effect. real effect. Therefore, for quite a long period of time, people have devoted themselves to the development of large-tonnage rollers. The largest tire rollers once weighed more than 200 tons. However, during this period, the changes in rollers mainly reflected the improvement of power and appearance.
