The present invention provides an asphalt additive comprising a tire rubber powder
and a petroleum resin. This asphalt additive is used in preparation of a reformed
asphalt and paving material, which is effective in reduction of noise from traffic,
minimization of crevice from contraction of road in winter and plastic deformation
of road in summer, prevention of traffic accidents due to slippery road when raining,
and prevention of water curtain and splash. Further, the road structure employing
the present invention is helpful for protection of water resource. Moreover, the
