The present invention relates to a construction method to form a waterproofing layer on a sub base, a base or a bridge surface of a general asphalt pavement layer, and pave stone mastic asphalt on the waterproof layer. According to the present invention, a modification mixture and a filling mixture are added to the waterproof layer, so waterproof function together with organic combination between an upper and a lower layer of the waterproof layer is improved in comparison with a general tack coat or prime coat. Since stone mastic asphalt using the same modification and filling mixture as that of the waterproof layer is formed on the upper part of the waterproof layer, and at the same time, interlocking of aggregates of stone mastic asphalt mixture is used, durability of pavement is increased. Moreover, porous aggregates are paved on the upper part of the stone mastic asphalt; freeze-thaw resistance is improved. |
