The invention relates to an in-situ heat regeneration remixing and paving technology of an asphalt pavement, which is characterized by particularly comprising the following steps of 1, construction preparation: 1) mechanical equipment and instrument debugging and maintenance preparation, 2) raw material preparation and technical index detection, and 3) pavement sweeping and guide line scribing, 2, paved antiskid layer asphalt mixture mixing, 3, paved antiskid layer asphalt mixture transport, 4, pavement heating, 5, pavement scarifying, 6, regenerant spraying and stirring, 7, spreading, 8, rolling, 9, traffic access, and 10, technical index check. The curing construction technology of the asphalt pavement can allow waste to be recycled; the original pavement is not required to be milled; the whole endurance and the service life of the pavement are improved and prolonged; the construction speed is high; the traffic access speed is high; the safety and the efficiency of the transport are improved; the cost is saved; occupational health is facilitated; and the technology is environment-friendly and energy-saving.
