Description

Technical Field

[0001] The utility model relates to the technical field of asphalt regeneration agent defoaming, in particular to a defoaming device for asphalt regeneration agent production. Background Art

[0002] Asphalt regeneration agent is a new type of material used for early and mid-term maintenance of asphalt pavement. Its core component is recycled asphalt, which is extracted and processed from abandoned asphalt pavement. It has significant characteristics: strong plasticity, excellent anti-aging, high viscosity, strong crack resistance and high temperature sensitivity. In addition, asphalt regeneration agent also incorporates asphalt extenders, anti-aging agents, fillers and other additives to improve its performance and service life.

[0003] Its main application is to repair early and mid-term diseases of asphalt pavement, such as microcracks, cracks, web cracks, looseness, roughness, water seepage, slight slurrying, material segregation after construction, asphalt peeling caused by insufficient adhesion between asphalt and aggregate, and excessive void ratio in asphalt pavement.

[0004] However, the presence of foam affects the performance and quality of asphalt regeneration agent. Foam will occupy part of the volume of asphalt, resulting in a reduction in the effective components of asphalt, which in turn affects its use effect. In addition, foam may also accelerate the aging process of asphalt and shorten its service life. After the foam bursts, the moisture and air in it will accelerate the oxidation and hardening of asphalt, resulting in reduced asphalt performance. At the same time, foam will also affect the various performance properties of asphalt regeneration agent, such as adhesion, anti-aging, anti-fatigue, etc., which will affect the service life and safety of asphalt pavement. Finally, the voids formed by foam in asphalt may also affect the density and flatness of asphalt pavement, thereby having an adverse effect on the construction effect and use effect of the pavement.
