Production processes of rock asphalt modified asphalt and mixture
A technology of modified asphalt and production process, which is used in building thermal insulation materials, building components, buildings, etc., can solve the problem that the dynamic stability of asphalt mixture is not very high, the high temperature rutting resistance of rock asphalt is not significant, and the processing technology of modified asphalt is not enough. Insufficient maturity and other problems to achieve the effect of improving water damage resistance, simple and easy processing, and reducing temperature sensitivity

Example Embodiment
[0033] Example 1
[0034] The technical scheme of the present invention is a production process of rock asphalt modified asphalt, and the process includes the following processing steps:
[0035] Step 1: Put the base asphalt into an asphalt tank with a stirring device and heat it to 160°C, then turn on the stirring device;
[0036] The second step: On the basis of the first step, add part of the rock asphalt and stabilizer slowly and at a constant speed, stir while adding, wait until the temperature is heated to 175°C, and stir at this temperature for 30 minutes;
[0037] The third step: on the basis of the second step, add the remaining asphalt and continue stirring for 1.5 hours to completely dissolve the asphalt particles. The part of the rock asphalt is 1 / 2 of the total amount of rock asphalt added;
[0038] The fourth step: on the basis of the third step, move the prepared rock asphalt modified asphalt into the finished product storage tank, and stir appropriately during storage.

[0050] Example 2
[0051] On the basis of Example 1, a preferred embodiment of the present invention is also in the production process of rock asphalt modified asphalt:
[0052] Step 1: Put the base asphalt into an asphalt tank with a stirring device and heat it to 155°C, then turn on the stirring device;
[0053] The second step: On the basis of the first step, add part of the rock asphalt and stabilizer slowly and at a constant speed, stir while adding, wait until the temperature is heated to 170°C, and stir at this temperature for 40 minutes;
[0054] The third step: on the basis of the second step, add the remaining bitumen and continue stirring for 1 hour to completely dissolve the bitumen particles. The partial rock bitumen is 1 / 3 of the total amount of rock bitumen added;
[0055] The fourth step: on the basis of the third step, move the prepared rock asphalt modified asphalt into the finished product storage tank, and stir appropriately during storage.

[0066] Example 3
[0067] On the basis of Example 1, a preferred embodiment of the present invention is also in the production process of rock asphalt modified asphalt:
[0068] Step 1: Put the base asphalt into an asphalt tank with a stirring device and heat it to 165°C, then turn on the stirring device;
[0069] The second step: On the basis of the first step, add part of the rock asphalt and stabilizer slowly and at a constant speed, stir while adding, wait until the temperature is heated to 180°C, and stir at this temperature for 20 minutes;
[0070] The third step: on the basis of the second step, add the remaining asphalt and continue stirring for 1.2 hours to completely dissolve the asphalt particles. The part of the rock asphalt is 1 / 2 of the total amount of rock asphalt added;
[0071] The fourth step: on the basis of the third step, move the prepared rock asphalt modified asphalt into the finished product storage tank, and stir appropriately during storage.
