Embodiment 3
[0030] Example 3 The asphalt regenerant used for asphalt thermal regeneration of asphalt pavement, the mass percentage of each component is as follows:
[0031] Aromatic oil 49.5%
[0032] Heavy oil 20%
[0033] Liquid petroleum resin 30%
[0034] Stabilizer 0.5%.
[0035] In each of the above-mentioned embodiments: one or more of furfural oil, extracted oil, rubber oil, etc. are selected as the aromatic oil, which is characterized in that the aromatic content is not less than 80%, and the flash point is greater than 220°C. The heavy oil is petroleum-grade heavy fuel oil or burning oil; the liquid petroleum resin is selected from Qilu Petrochemical, and the resin can be well compatible with aromatic oil and heavy oil. The stabilizer is preferably sulfur-based asphalt stabilizer from Lanzhou Lanyue Chemical Co., Ltd., the main component is sulfur, which is an existing commercial product.
