Abstract:
The present invention relates to a pellet type SBS-asphalt master batch modifier composition comprising styrene-butadiene-styrene (SBS) block copolymer and asphalt, and modified asphalt prepared by melting and mixing the pellet type SBS-asphalt master batch modifier composition with asphalt. The modified asphalt prepared thereof has advantages that deterioration of physical properties and thermal oxidation can be prevented while productivity can be improved due to reduced melting time of modifier.
