Background

Currently, asphalt concrete pavements have many excellent properties. The porosity of an asphalt concrete pavement in highway engineering is generally 3-5%, and the porosity still has a reduced space. The first condition for compacting the bituminous mixture is to apply the necessary external force and work to rearrange the particles inside the compacted material; the second condition is that the compacted material must maintain a stable structure during compaction without "flowing" under the influence of external forces. The existing static steel wheel road roller can improve the compaction degree by increasing the weight of the road roller within a certain range, but the compaction degree is difficult to improve by increasing the weight beyond a certain limit, and the energy consumption of the whole machine can be greatly increased. The static road roller has less plastic deformation to the compacted material, so that the static road roller is a compacting machine with lower efficiency and is mainly used for carrying out initial compaction on the asphalt pavement.
