Embodiment 1
[0023] A cold asphalt reclaimer, including sizing agent and desiccant:
[0024] The component percentage of described wetting agent is:
[0025] Rubber oil 25% 120# solvent oil 30%
[0026] 0# diesel oil 8% synthetic rubber SBS 15%
[0027] C9 petroleum resin 22%
[0028] The composition percentage of described desiccant is:
[0029] Ethyl Acetate 40% Oleamide 60%
[0030] The application of asphalt cold regeneration agent in cold recycled asphalt concrete is as follows: mix the aged asphalt mixture (RAP) after milling at normal temperature and pressure at a ratio of sizing agent: aged asphalt = 1.3:1 Combine the aged asphalt mixture into a sizing material, and after stacking and storing for 8 days, mix the desiccant and the sizing agent in a ratio of 1:4 to the sizing material at normal temperature and pressure until the solvent in the sizing material volatilizes. A cold recycled asphalt mixture is obtained; wherein the content of the aged asphalt accounts for 5% of the ...

[0035] A cold asphalt reclaimer, including sizing agent and desiccant:
[0036] The component percentage of described wetting agent is:
[0037] Rubber oil 15% 120# solvent oil 40%
[0038] 0# diesel oil 10% synthetic rubber SBS 20%
[0039] C9 petroleum resin 15%
[0040] The composition percentage of described desiccant is:
[0041] Ethyl Acetate 60% Oleamide 40%
[0042] The application of asphalt cold regeneration agent in cold recycled asphalt concrete is as follows: mix the aged asphalt mixture (RAP) after milling at normal temperature and pressure at a ratio of sizing agent: aged asphalt = 1: 1.5 Combine the aged asphalt mixture to make the soaking material. After stacking and storing for 10 days, mix the desiccant and the soaking agent in a ratio of 1:5 at normal temperature and pressure to obtain the cold recycled asphalt mixture. ; Wherein the content of the aged asphalt accounts for 3% of the aged asphalt mixture.

Embodiment 3
[0047] A cold asphalt reclaimer, including sizing agent and desiccant:
[0048] The component percentage of described wetting agent is:
[0049] Wetting agent:
[0050] Rubber oil 40% 120# solvent oil 20%
[0051] 0# diesel oil 5% synthetic rubber SBS 30%
[0052] C9 petroleum resin 5%
[0053] Desiccant:
[0054] Ethyl Acetate 70% Oleamide 30%
[0055] The application of asphalt cold regeneration agent in cold recycled asphalt concrete is as follows: mix the aged asphalt mixture (RAP) after milling at normal temperature and pressure according to the ratio of sizing agent: aged asphalt = 1.5:1 Combine the aged asphalt mixture to make the soaking material. After stacking and storing for 6 days, mix the desiccant and the soaking agent according to the ratio of 1:5 at normal temperature and pressure to obtain the cold recycled asphalt mixture. ; Wherein the content of the aged asphalt accounts for 6% of the aged asphalt mixture.
