The invention provides a kind of colored asphalt, which is prepared from the following raw materials. The raw materials include: 20-50 parts by weight of petroleum resin; 5-20 parts by weight of thermoplastic resin; 1-10 parts by weight of rubber-based asphalt modifier; aromatic oil 20-66 parts by weight; 5-35 parts by weight of color dye. Compared with the prior art, the present invention adds a rubber-based asphalt modifier, a thermoplastic resin and aromatic oil to the preparation of the colored asphalt, and utilizes the rubber-based asphalt modifier to improve the low-temperature performance of the colored asphalt, and the thermoplastic resin makes the colored asphalt have Good high temperature performance and high softening point, and the high strength, high resilience and good impact resistance of thermoplastic resin can improve the tear strength, fatigue resistance and wear resistance of colored asphalt, and use aromatic oil to promote The swelling of the polymer in the system increases the stability of the system and reduces the generation of segregation. |
