Technical Field

The utility model relates to a technical field of pitch production especially relates to a cold regeneration agitated vessel of pitch.

Background

The asphalt mixture for the road is basically the traditional hot-mix hot-paving. The pollution of dust and asphalt smoke to the environment is inevitable in the production and construction process, and although many measures are taken in recent years, a large amount of capital is invested, and the pollution problem is difficult to solve.

The key to research on cold mixing and cold paving of the asphalt mixture is the development of the modified emulsified asphalt for cold mixing. The modified emulsified asphalt is widely applied to road surface layers, such as slurry seal, micro-surfacing, sand-containing fog seal, cold-patch and the like. At present, no mature large-scale production process and equipment exist.
