Abstract

See full text

The disclosure discloses a high-viscosity, high-elasticity, and anti-aging composite modified asphalt and a preparation method thereof, belongs to the technical field of road engineering materials, and solves the technical problem that the comprehensive performance of an existing asphalt ultrathin wearing layer needs to be further improved so as to prolong the service life of a pavement surface layer and reduce the pavement maintenance costs. The composite modified asphalt is prepared from the following components in parts by mass: 100 parts of a matrix asphalt, 10 to 15 parts of a thermoplastic styrene-butadiene rubber, 5 to 8 parts of a tackifier, 0.5 to 1.5 parts of a plasticizer, 2 to 5 parts of a compatibilizer, 0.1 to 0.4 parts of a stabilizer, and 0.01 to 0.05 parts of an anti-aging agent. The composite modified asphalt prepared by the disclosure has the advantages of high elasticity, high viscosity, excellent aging resistance, etc.
