[0002] When laying asphalt pavement, the asphalt needs to be pre-spread before laying to ensure the flatness of the road surface after compaction. When laying asphalt on the road surface of some small parks, due to the narrow road surface and small space of the park, the existing large-scale asphalt concrete paving equipment cannot enter, and the asphalt concrete can only be spread manually and then compacted with a roller. Manual paving will cause potholes and unevenness in the compacted road surface due to differences in workers' techniques, and multiple repairs are required to make the road surface flat, which will cause a waste of manpower and material resources. Therefore, we provide an asphalt concrete paving auxiliary equipment, which is pulled by a pulling device, and guide rails are set on both sides of the road. A scraping device is set on the guide rails, and the scraping device is pulled by the pulling device to move on the guide rails, thereby scraping the asphalt flat, achieving a smooth asphalt paving in one time, and greatly reducing the amount of manual work.
