Embodiment 1
[0014] Embodiment 1: as figure 1 As shown, 1. Heat 7 tons (t) of AH-70 matrix asphalt in the matrix storage tank to 120°C.
[0015] 2. Put 3 tons of lake bitumen into the melting tank for complete melting at 165°C.
[0016] 3. Pump the base bitumen to the mixing tank; pump the TLA lake bitumen from the melting tank to the mixing tank.
[0017] 4. Turn on the agitator of the mixing tank to stir the mixture of matrix asphalt and TLA lake asphalt for 30 minutes, while the temperature in the mixing tank is kept at 170°C.
[0018] 5. After the mixing is completed, TLA lake asphalt and base asphalt are uniformly mixed, which is qualified modified asphalt for this application of lake asphalt.
Embodiment 2
[0019] Example 2: 1. Heat 9.5t of AH-70 base asphalt in the base storage tank to 130°C.
[0020] 2. Put 0.5t of lake bitumen into the melting tank for complete melting at 175°C.
[0021] 3. Pump the base bitumen to the mixing tank; pump the TLA lake bitumen from the melting tank to the mixing tank.
[0022] 4. Turn on the agitator of the mixing tank to stir the mixture of matrix asphalt and TLA lake asphalt for 20 minutes, while the temperature in the mixing tank is kept at 170°C.
[0023] 5. After the mixing is completed, TLA lake asphalt and base asphalt are uniformly mixed, which is qualified modified asphalt for this application of lake asphalt.
Embodiment 3
[0024] Example 3: 1. Heat 2t, AH-110 base asphalt in the base storage tank to 140°C.
[0025] 2. Put 8 tons of lake bitumen into the melting tank for complete melting at 195°C.
[0026] 3. Pump the base bitumen to the mixing tank; pump the TLA lake bitumen from the melting tank to the mixing tank.
[0027] 4. Turn on the agitator of the mixing tank to stir the mixture of matrix asphalt and TLA lake asphalt for 50 minutes, while the temperature in the mixing tank is kept at 170°C.
[0028] 5. After the mixing is completed, TLA lake asphalt and base asphalt are uniformly mixed, which is qualified modified asphalt for this application of lake asphalt.
