Because the invention fully considers that the asphalt tanks 1 with different volumes are adopted, and the asphalt filling amounts are different, the asphalt filling time also changes, so the invention sets the volume of the asphalt tank as V and the total time for filling the asphalt into the kneading pot as t. When asphalt is filled, in the first step, 0.5V of asphalt is uniformly added in 0.4t of time; secondly, evenly adding 0.4V asphalt in the next 0.4t time; thirdly, 0.1V of asphalt is uniformly added in the last 0.2t of time. When V is 2000L, the time t is 3-5 minutes; for each 1000L increase in volume V, time t increases by 1 minute. That is, when the asphalt tank 1 having a volume of 2000L is used, the overall time for filling asphalt is 3 to 5 minutes, and the overall time is 4 minutes in the present embodiment. When the asphalt tank 1 with the volume of 4000L is adopted, the total time for filling asphalt is 5-7 minutes; when using an asphalt tank 1 with a volume of 5000L, the total time for filling asphalt is 6-8 minutes, and so on.

The invention fully considers the influence of asphalt temperature, thus the temperature of asphalt is also collected before asphalt is filled, the invention collects asphalt temperature through the temperature measuring instrument 8 arranged on the asphalt tank 1, and the temperature measuring instrument 8 can send the collected temperature signal to the control and regulation unit 12. The control and regulation unit 12 can then determine the total time for filling asphalt according to the collected asphalt temperature, and divide the determined total time into three steps of time for filling asphalt, while the rotational speed of the asphalt pump 5 at each step of filling asphalt can be determined according to the volume V of the corresponding asphalt tank 1.
The asphalt temperature is set as T, and the asphalt temperature acquired by the temperature measuring instrument 8 before asphalt filling is set as T, and the T is 183-187 ℃. As the high-temperature asphalt is processed in the previous step, the temperature of the asphalt fluctuates, and when the temperature T rises by 5 ℃, the asphalt filling time T is correspondingly reduced by 5%; every time the temperature T is reduced by 5 ℃, the asphalt filling time T is correspondingly increased by 5%.
According to the invention, the high-temperature asphalt oil is filled into the lower mixing kneading pot in a high-pressure state by adopting a three-step asphalt filling mode, so that the high-temperature asphalt oil can be quickly and efficiently added, the wetting effect of asphalt on dry materials is good, the mixing kneading is uniform, the production efficiency is improved, and the paste quality is also improved. The invention also takes account of the temperature characteristic of the asphalt, so that the corresponding filling time is adjusted according to the temperature of the asphalt, and the paste quality of the invention is higher.
As described above, the present invention can be advantageously practiced.
