[0002] When cracks appear in the asphalt concrete pavement, it provides a channel for water to enter the pavement. The water penetrates into the pavement base course and subgrade, which may cause the softening of the base course and the settlement of the subgrade, and further exacerbate problems such as the expansion of cracks and the damage of the pavement. The repair of cracks in the asphalt concrete pavement is an important part of road maintenance, aiming to prevent the further expansion of cracks, reduce water penetration, and extend the service life of the pavement.

[0003] For the cracks in the asphalt concrete pavement, hot asphalt mixture is commonly used for repair work. However, the fluidity of the asphalt mixture is poor. Usually, the asphalt mixture can only be laid above the cracks, and manual labor is still needed to further tamp the asphalt mixture into the cracks for filling. The repair efficiency is low, the operation is time-consuming and laborious, and the filling effect of tamping the asphalt into the cracks is poor, which is likely to result in unqualified repair quality.
