Asphalt concrete prefabricated part based on solid waste material and preparation method of asphalt concrete prefabricated part

The invention belongs to the field of recycling of renewable resources (road engineering), and particularly relates to an asphalt concrete prefabricated part based on a solid waste material and a preparation method of the asphalt concrete prefabricated part. According to the invention, after the waste pavement reclaimed material and the waste plastic powder are mixed according to a certain proportion, microwave heating is carried out to prepare the asphalt concrete prefabricated part, so that 100% utilization of the pavement milling material is realized, the waste fine material with high asphalt content is fully utilized, the use amount of new asphalt is saved, and the production cost is greatly reduced; the microwave heating mode is adopted, compared with the traditional heating mode, the microwave heating mode has the advantages that the heating speed of the mixture is high, the secondary aging of the new and old asphalt is reduced, the softening and melting effects of the heated waste plastic powder can be
