Auto-processing technology and system for modified asphalt

Abstract

The invention discloses auto-processing technology and system for modified asphalt and relates to the field of asphalt processing. The system includes: a swelling tank assembly, a heating device, a modifier feeding system, a storage tank, a milling machine, and a control device. A stirrer and a temperature sensor are disposed in the swelling tank assembly; the heating device heats the swelling tank assembly; the modifier feeding system is connected with the swelling tank assembly for feeding a modifier thereinto; the storage tank is used for storing asphalt and is connected to the swelling tank for feeding matrix asphalt to the swelling tank assembly; the control device is electrically connected with the stirrer, the temperature sensor and the heating device. Modified asphalt produced in the system can effectively improve high-temperature stability of road surface and reduces generation of tracks and improves low-temperature performance of the road surface, thus preventing road surfacecracking, effectively preventing early stage damage of the road surface, reducing maintenance and repair load, and prolonging service life of the road surface.

Description

technical field [0001] The invention relates to the field of asphalt processing, in particular to a modified asphalt self-processing process and system. Background technique [0002] With the rapid development of national infrastructure, the improvement of road grades, and the increasing traffic volume and traffic load, asphalt concrete pavement, as an exposed project to bear the weight of vehicles, resist wheel wear and keep the road surface smooth, requires the pavement to have sufficient strength, relatively High stability, certain flatness, and proper anti-skid ability to reduce damage to road surfaces and vehicle parts, maintain a good line of sight, and reduce environmental pollution. Among them, modified asphalt refers to the asphalt mixture made by adding modifiers to asphalt to improve the road performance of asphalt. Compared with ordinary asphalt, SBS modified asphalt has good rutting resistance, strong cold resistance, and good strain capacity under heavy load a...

Problems solved by technology

[0005] (2) The transportation time increases, which brings about a decrease in the temperature of the modified asphalt, product segregation, secondary heating after arriving at the construction site, accelerated product aging, segregation, and a sharp drop in quality, etc.

[0006] (3) The SBS modified asphalt transported to the construction site appears in the form of finished products, and it is difficult to check the core components such as matrix asphalt and SBS modifier, which can easily lead to unqualified asphalt concrete products; For example, by mixing some low-priced and inferior asphalt, or adding chemical modifiers to reduce the amount of SBS modifier used to make the index of modified asphalt falsely high, etc., the final result is that although the index of SBS modified asphalt meets the modified The road performance of asphalt is extremely poor, which will have a fatal impact on the quality of the entire asphalt pavement

[0007] (4) The production of SBS modified asphalt factory is for profit, and the product profit is large and opaque

[0008] (5) SBS modified asphalt is produced by the factory, and the supplier is for the purpose of operation. If the supply exceeds the demand, it is difficult to guarantee the unit price of the purchase, and even directly affect the construction progress
