Layered stripping device for aged asphalt on surface of recycled asphalt pavement material

Abstract

The invention belongs to the technical field of asphalt stripping devices, and relates to a layered stripping device for aged asphalt on the surface of a recycled asphalt pavement material. The device comprises a bottom frame, a top frame is arranged above the bottom frame, sealing plates are detachably installed on the outer end faces of the bottom frame and the top frame, a driving mechanism is installed between the bottom frame and the top frame, and the driving mechanism is in transmission connection with a first stripping mechanism and a second stripping mechanism. The driving mechanism is in transmission connection with the first stripping mechanism and the second stripping mechanism, so that the first stripping mechanism and the second stripping mechanism can move oppositely or reversely by arranging the driving mechanism, layered stripping of aged asphalt is realized, and the automation degree is high; height adjustment of a connecting plate and a scraper can be achieved by arranging an air cylinder and a lifting column, so that the purpose of stripping asphalt with different thicknesses can be achieved; and height adjustment of a transverse plate and a scraper can be achieved by arranging a hydraulic cylinder and a telescopic column, so that the purpose of stripping asphalt with different thicknesses can be achieved, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of asphalt stripping devices, in particular to a layered stripping device for aging asphalt on the surface of recycled asphalt pavement materials. Background technique [0002] Recycled asphalt pavement refers to the pavement that uses recycled asphalt mixture as the surface layer. The regeneration of asphalt is the reverse process of aging. Usually can be mixed with regeneration agent, such as mixed with corn oil, lubricating oil and so on. After mixed with rejuvenator, the relative content of asphaltene is reduced, and the dissolving ability of soft asphaltene to asphaltene is improved, the compatibility of asphalt is improved, the penetration and ductility of asphalt are improved, and the performance is restored or close to the original. [0003] After a long time of use, asphalt is easy to age and needs to be stripped. However, the traditional technology mostly uses manual stripping, which has low work ...
