To provide an asphalt waterproofing construction method and a waterproofing layered structure for dispensing with an asphalt heating and melting process by flame and a complicated laying process.

In this asphalt waterproofing construction method and the waterproofing layered structure, a reformed asphalt roofing is laid on a waterproofing substrate layer through a normal temperature hardening type reformed asphalt compound at normal temperature. Since the construction work at high temperature is not required and a bad smell and smoke do not occur, this asphalt waterproofing construction method is environment-friendly, its efficiency is more improved than that of a conventional construction method, and labor required for the work can be saved to provide the waterproofing layered structure having excellent waterproofing performance.
