Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to an asphalt warm mixing and modification production device. Background Art

[0002] Warm mix asphalt is a technology that reduces the production temperature of traditional hot mix asphalt mixtures by adding specific additives (such as chemical modifiers or physical modifiers). Asphalt modification is a process of changing the properties of ordinary asphalt by adding specific modifiers to it or using physical or chemical methods to improve the asphalt's high temperature stability, durability, anti-aging, construction and ease of use.

[0003] However, in the prior art, asphalt generates heat during the production of the mixture, and the heat generated is usually not used, resulting in a waste of energy. The traditional mixing method is not convenient for cleaning the asphalt attached to the inner wall of the mixing barrel, so the asphalt is unevenly mixed, which reduces the quality. In addition, asphalt needs to be modified during production. Modified asphalt can improve high-temperature stability and aging resistance. However, external admixtures such as ground rubber powder or other fillers added during the modified production are prone to agglomeration, and the agglomerated materials will affect the quality of the modified asphalt.
