Embodiment 1
[0029] Take 100g of coal tar pitch and add it to the reaction kettle, raise the temperature to 115°C to completely melt the coal tar pitch, add 40g of aromatic oil as a diluent, and stir at a speed of 700rpm for 1 hour; keep the temperature and speed constant, add 0.04g of hindered phenolic Oxygen 1076, add 0.8g hindered amine anti-aging agent DQC after 0.5 hours, continue to stir for 1.5 hours, cool and discharge to obtain the aging-resistant coal tar pitch product.
[0030] The softening point, penetration, ductility and aging resistance are tested according to the methods stipulated in "GBT 5180-2010 Petroleum Asphalt for Heavy Traffic Roads" and "JTG F40-2004 Technical Specifications for Construction of Highway Asphalt Pavement".
Embodiment 2
[0032] The implementation steps are the same as in Embodiment 1. The difference is: use residual oil of equal quality to replace aromatic oil, and hindered phenol antioxidant 1520 to replace 1076.
[0033] The performance evaluation method is the same as in Example 1.
Embodiment 3
[0035] The implementation steps are the same as in Embodiment 1. The difference is: 0.10 g of hindered phenol antioxidant 1520 replaces 0.03 g of hindered phenol antioxidant 1076.
[0036] The performance evaluation method is the same as in Example 1.
