Abstract: A device for forming a prepressing-assembled asphalt mixture surface layer comprises: a wheel compaction module and a prepressing forming module. The wheel compaction module is configured to preliminarily compact a hot mix asphalt mixture. The prepressing forming module comprises a second reaction frame. A second loading device is hung at a top of the second reaction frame. An output end of the second loading device is fixedly connected to a prepressing plate. A conveyor belt passes through lower parts of the wheel compaction module and the prepressing forming module. A base is arranged on the conveyor belt. A surrounding mold is circumferentially fixed to the base. Through the prepressing module and the process, the device continuously applies a compaction load to the hot mix asphalt mixture surface layer, and effectively increases the adhesion between the aggregate and the asphalt to improve the strength of the assembled asphalt pavement.
