Description

Technical Field

[0001] The utility model relates to the field of asphalt processing, in particular to a matrix asphalt heating device. Background Art

[0002] Asphalt is a very important material in road construction and maintenance. Ordinary asphalt usually refers to road asphalt, which is obtained by refining crude oil. It has a large viscosity and good temperature stability, but its weather resistance and chemical resistance are relatively low. Matrix asphalt is further processed on the basis of ordinary asphalt. During the preparation of matrix asphalt, a certain proportion of modifiers, such as polymers, rubbers or other chemicals, are usually added to improve its performance. The modified matrix asphalt has better high temperature stability, anti-rutting performance, weather resistance and chemical resistance. The improvement of these properties makes the application range of matrix asphalt in road construction and maintenance wider, especially in projects with high requirements such as highways and airport runways. Since the matrix asphalt is usually not completely melted but softened when used, it still maintains a certain viscosity and stickiness, but the matrix asphalt is heavy and difficult to be stirred evenly when stirred, so that part of the matrix asphalt may be deposited at the corners at the bottom of the stirrer and cause adhesion and lumps.
