The present invention relates to an asphalt pavement method capable of forming a water-permeable base course to obtain effects of solving a problem that underground water becomes exhausted and of preventing a heat island effect on a paved road in summer and floods by enabling moisture to remain inside asphalt as water permeability of the base course of an asphalt-paved road is improved by forming pores. To achieve the same, in the asphalt pavement method paving asphalt by successively constructing a subgrade, a roadbed, an anti-frost layer, a sub-base, the base course, an intermediate base, and a surface course on the natural ground, the present invention is characterized by constructing the base course using a composition containing 20-25 wt% of 30-mm aggregates, 30-40 wt% of 25 mm aggregates, 15-25 wt% of 20 mm aggregates, 5-20 wt% of 13 mm aggregates, 5-10 wt% of 4 mm or smaller aggregates, 3-6 wt% of a filler, and 3-6 wt% of radial type SBS (RSBS) modifier. |
