[0045] Hereinafter, embodiments of the present invention will be described in detail. First, a water-based epoxy primer (Toughguard RW primer, manufactured by Nippon Paint Co., Ltd.) is applied to the foundation concrete. After the primer is dried, a two-component curing polyurea resin (two-component curing type) is applied to form a waterproof layer. Component curing resin A) (Tough guard RG or Tough guard RM, both manufactured by Nippon Paint Co., Ltd.). Then, apply a two-component curable polyurea resin (two-component curable resin B) (Toughguard RP, manufactured by Nippon Paint Co., Ltd.) to form an adhesive waterproof layer, and pave it on top of it before curing to form a pavement Layer of asphalt mixture.
[0046] In this embodiment, the coating amount of the water-based epoxy primer used is 0.04 kg per 1 square meter, and the coating amount of the two-component curing polyurea resin (two-component curing resin A) is 1.1 kg per 1 square meter (1mm in thickn...
