Indoor forming-based asphalt pavement structure interlayer interface nondestructive separation method

The invention discloses an indoor forming-based asphalt pavement structure interlayer interface nondestructive separation method. The method comprises the following steps of: forming a lower structurein an asphalt pavement composite structure test piece, putting an ultrathin isolation film with two surfaces coated with an oil-water mixed solution above the lower structure, forming an upper structure in the asphalt pavement composite structure test piece, and separating the upper and lower structure layers of the composite test piece along the interlayer interface along the central axis direction of the composite test piece. The method realizes nondestructive separation of the indoor formed asphalt pavement structure interlayer interface, and has an obvious separation effect; and the separated composite test piece has the advantages of complete interlayer interface of the upper and lower structure layers, clear surface texture, obvious construction characteristics, protruding surface characteristics and abunda
