Dry type asphalt modifier composition preventing draindown characteristics and Modified asphalt containing the same

摘要

The present invention relates to a modified asphalt-containing asphalt modifier composition, and a drain-down anti-dry it, and more particularly it is a styrene-butadiene-styrene block copolymer, tackifier resin, to a dry asphalt modifier and modified asphalt containing them comprising a process oil, and cellulose fibers. The dry asphalt modifier of the present invention is a cellulose fiber absorbs the developer falls down the drain asphalt is asphalt aggregate flows in suppressed and the dispersion rate of the modifying agent when manufacturing the asphalt concrete can be increased to produce asphalt concrete of higher quality, dry modified asphalt containing asphalt modifier for the production of asphalt in the dry type, drainage asphalt pavement construction methods, stone mastic can be usefully applied to asphalt pavement construction methods.
