Influence of Roller Rolling Speed on Compaction Effect

The rolling speed affects the compaction time of the material per unit area by the vibrating wheel. When the rolling speed is low, the number of vibrations per unit area is more than when the rolling speed is high, so the energy acting on the pressed material is more in the former than in the latter. In fact, the energy transferred into the layer of material being pressed is inversely proportional to the rolling speed. Assuming that the compaction energy required to achieve the specified compactness of the rolled material layer remains unchanged when the rolling speed is doubled, the number of rolling times is roughly doubled.
