Description

Technical Field

[0001] This application relates to the technical field of asphalt addition, and particularly to a small device for uniformly adding thermostatic hot asphalt. Background Art

[0002] Emulsified asphalt refers to asphalt heated to a flowing state and dispersed in water containing emulsifiers and stabilizers in the form of fine droplets through mechanical action to form a uniform and stable emulsified liquid asphalt.

[0003] Currently, when preparing asphalt in large quantities, large fully automatic equipment can be used to control relevant parameters such as the addition speed and temperature of materials. However, when producing emulsified asphalt in small batches in the laboratory, molten hot asphalt often needs to be added manually. During this process, it is difficult to accurately control the addition speed of asphalt. At the same time, during the addition of asphalt, the hot asphalt is at room temperature, its heat will quickly dissipate, and its viscosity will also increase, making the asphalt difficult to be emulsified. Eventually, the composition of the emulsified asphalt does not match the design, and the quality cannot meet the usage requirements. Utility Model Content
