The invention discloses an
asphalt mixture seam plaster for alleviating pavement cracks and a preparation method thereof, and the
asphalt mixture seam plaster comprises the components of 16-18% of
petroleum asphalt, 4-6% of building asphalt, 23-26% of a compatilizer, 3-5% of a
thermoplastic elastomer, 1-3% of high temperature resin, 25-32% of waster rubber
powder, 20-26% of talcum
powder and 0.2-0.6% of a stabilizer. The preparation method is as follows: heating the
petroleum asphalt, then adding the
petroleum asphalt into the building asphalt for even mixing, after heating, beating into a working tank, and adding the compatibilizer; adding the
thermoplastic elastomer and the high temperature resin, and shearing and finely
grinding by a
colloid mill while stirring to obtain a mixture; beating the mixture into a development horizontal tank, adding the
waste rubber powder, the talcum powder and the stabilizer, stirring at 165-185 DEG C for development for 3-4H to obtain a cementing material; extruding for molding the cementing material and packing. The asphalt mixture seam plaster has the advantages of strong adhesion and self restoring deformation ability, can greatly improve high temperature deformation resistance, low temperature
cracking resistance and
fatigue resistance of asphalt pavements, reduces effectively alleviates
asphalt pavement cracks, increases driving comfort, and reduces
road construction investment frequency.
