To provide a waterproof construction method for an asphalt pavement, capable of causing no environmental pollution, and constructing or repairing an asphalt pavement road having both high adhesive force and waterproof performance, and high quality in a short construction period.

An adhesive and waterproof layer 83 of asphalt is formed between a bed 6 and an upper layer 7 of asphalt mixture having open grading aggregate by laying an asphalt sheet. The layer 83 is mainly composed of asphalt, and works as an adhesive material between the layers, and also works as a waterproof layer for preventing rainwater permeating into a drain layer formed by the asphalt mixture having open grading aggregate from leaking to the bed side. Thus, scattering of chemicals is prevented so as to prevent environmental pollution, drying work is eliminated not to require wait time, and further the adhesive and waterproof layer 83 having uniform thickness is formed without air bubbles.
