Example Embodiment
[0021] Example 1
[0022] A recycled asphalt mixture, comprising the following components by weight: 100 parts of base asphalt, 20 parts of recycled asphalt treatment material, 3 parts of regenerating agent, 3 parts of SBS modifier, 3 parts of film-forming substance, 0.1 part of niobium carbide, 0.3 parts of zinc stearate and 2 parts of thickener.
[0023] Preferably, the regenerant is formed by mixing furfural extract oil and aromatic oil in a weight ratio of 1:1.
[0024] Preferably, the thickener is made by mixing rosin and calcium lignosulfonate at a weight ratio of 10:1.
[0025] Preferably, the film-forming substance is formed by mixing fluorocarbon resin and cottonseed oil in a weight ratio of 100:7.
[0026] Preferably, the recycled asphalt treatment material is obtained by soaking the recycled asphalt with a sodium hydroxide solution of 1 to 3 mol / ml for 1 hour, then washing and drying with water.
Example Embodiment
[0027] Example 2
[0028] A recycled asphalt mixture comprising the following components in parts by weight: 100 parts of base asphalt, 30 parts of recycled asphalt treatment material, 6 parts of regenerating agent, 3 parts of SBS modifier, 3 parts of film-forming substance, 0.1 part of niobium carbide, 0.3 parts of zinc stearate and 2 parts of thickener.
[0029] Preferably, the regenerant is formed by mixing furfural extract oil and aromatic oil in a weight ratio of 1:1.
[0030] Preferably, the thickener is made by mixing rosin and calcium lignosulfonate at a weight ratio of 10:1.
[0031] Preferably, the film-forming substance is formed by mixing silicone resin and linseed oil in a weight ratio of 100:7.
