PLANT MIX-TYPE ASPHALT MODIFIER COMPOSITION HAVING INCREASED MELTING RATE, AND MANUFACTURING METHOD FOR THE SAME

摘要

It is possible to increase the dispersing speed of the asphalt modifier during the production of the modified asphalt by finely dispersing waste paper such as newspaper in a process of preparing a plant mix type asphalt modifier composition containing a styrene-butadiene-styrene block copolymer as a main component using a melt mixing technique Further, it is possible to increase the dispersing speed of the asphalt modifier during the production of the modified asphalt without using the cellulose short fiber which is required to be treated separately before use and has an apparent specific gravity and is inconvenient for handling and use. Further, There is provided a plant mix type asphalt modifier composition with increased melting rate capable of inhibiting drain phenomenon in which asphalt flows down from an asphalt mixture without adding an additive, and a method for manufacturing the same.
