Background

Road rollers belong to the category of road and bridge engineering equipment in engineering machinery, and can be roughly divided into static pressure type road rollers, vibration type road rollers, impact type road rollers and the like according to the compaction principle. The static pressure type road roller is self-propelled static pressure equipment which compacts the road surface by self weight, and can be divided into a steel wheel road roller and a rubber wheel road roller according to the form of wheels. Wherein, rubber tyer road roller is widely used in carrying out the process of rolling to construction basic unit or pitch surface course. Generally, the paving temperature of the asphalt concrete is 145-165 ℃, the viscosity is high, the temperature is reduced quickly, and the asphalt concrete is basically molded when the temperature is 120 ℃. The steel wheel road roller needs to perform rolling operation within the temperature range of 120-165 ℃, and the rolling operation is completed before the temperature of the asphalt concrete is reduced to 120 ℃. In actual rolling construction, the temperature of steel wheels of a double-steel-wheel road roller is usually far lower than 120 ℃, the phenomenon that asphalt concrete adheres to the wheels is often caused, and the more the adhesive layer is, the thicker the adhesive layer is, the more the adhesive layer is, the influence is on the compaction quality and the leveling quality of a road surface.

Meanwhile, in the process of rolling construction, due to mechanical vibration, sand and asphalt blocks originally adhered to the steel wheel may fall off, so that the road surface at the corresponding position is suddenly raised, and the smoothness of the road surface is affected; in addition, because the road roller compacts the road surface through self dead weight in the construction process, the self weight of the road roller is insufficient in actual work, so that the compacting degree is insufficient, the road roller needs to be reworked or replaced for operation for many times, and the compacting efficiency of the existing road roller is low due to various reasons.
