PN.12810309 Pump for Bomag/Dynapac/Hamm Road Roller

Sprinkling water on asphalt pavement during road roller operation is a key operation to ensure compaction quality. Its core functions include: first, cooling and anti-adhesion. Asphalt is prone to sticking to the rolling wheel after high-temperature paving. Water sprinkling can quickly reduce the temperature of the wheel surface and asphalt, avoiding pavement wrinkles and roughness caused by mixture adhesion to the wheel, thus ensuring compaction flatness. Second, optimizing compaction effect. Moderate water sprinkling can reduce friction resistance between the rolling wheel and asphalt surface, allowing the road roller to transmit compaction force more smoothly, promoting tight combination of asphalt mixture particles, and improving pavement density and bearing capacity. Third, auxiliary dust suppression. Water sprinkling can suppress asphalt dust generated during compaction, improving the construction environment. It is necessary to control the water volume: excessive water may cause asphalt to cool too fast and reduce adhesion, while insufficient water cannot achieve anti-adhesion effect. The water volume should be dynamically adjusted according to asphalt temperature and ambient humidity.
