The invention relates to an instant high-glue
alloy asphalt modified material as well as a preparation method and application thereof. The preparation method comprises the following steps of: uniformly stirring and mixing heavy
asphalt aromatic hydrocarbon oil 207, 70 #
asphalt and a
needle penetration regulator in proportion to form a mixed oil material; adding
truck tire rubber
powder, uniformlystirring to obtain mixed rubber
powder, performing mechanochemical
extrusion activation modification through screw
extrusion equipment, feeding the mixed rubber
powder into a double-cone feeding device, uniformly feeding the mixed rubber powder and a
grafting activation modifier into a mixing and granulating
extrusion system in proportion under variable-frequency pushing, and performing
water cooling, isolation, spin-
drying, screening, air conveying, collection and packaging to obtain a finished product of the granular asphalt modified material. The instant high-glue
alloy asphalt modified material, the preparation method and the application solve the problems of high
processing energy consumption, unsafety, poor heat storage stability, large
smoke pollution and insufficient aging performance of the traditional waste tire rubber asphalt modified material, and have the advantages of good asphalt integration, less
grinding times, high mixing efficiency, strong waterproof performance andno pungent smell.
