ASPHALT MODIFIER, PROCESS FOR PRODUCING MODIFIED ASPHALT, AND PROCESS FOR PRODUCING ROAD PAVEMENT MATERIAL

摘要

An asphalt modifier containing 1-50 wt.% of asphalt. A modified asphalt is produced by mixing the asphalt modifier and asphalt. The asphalt modifier of this invention has excellent uniformity of dispersion into asphalt so that the asphalt modifier can be effectively uniformly dispersed into asphalt for a short time, thereby enabling a modified asphalt in which modifying ingredients are uniformly dispersed in the asphalt to be produced for a short time.
