A mobile recycled asphalt mixture cold mixing equipment and method for road construction

Abstract

The invention relates to moveable regenerative asphalt mixture cold stirring equipment and method for highway construction, and belongs to the technical fields of road and bridge construction equipment. The moveable regenerative asphalt mixture cold stirring equipment comprises a load bearing platform which is provided with a screening device, a stirring device, and a feeding device used for conveying sifted material to the stirring device; the screening device is internally provided with a screen mesh with adjustable grid gap size, and a discharge hole of the screening device is provided witha guide plate used for changing the flow direction of material; the stirring device comprises a shell body, a heating portion, a regenerative ring, and a stirring portion, a supporting roller is arranged at the lower part of the shell body is provided with, the heating portion, the regenerative ring, and the stirring portion are correspondingly arranged on a feeding inlet, and a middle part and the discharge hole of the stirring device. The moveable regenerative asphalt mixture cold stirring equipment and the method for the highway construction adopts the screen mash with adjustable grid gapsize as a tool for screening aggregate and regenerating material respectively to realize high concentration of equipment functions, equipment usage is decreased, the volume requirements of a carryingplatform are decreased, and the purpose of using the carrying platform to carry is achieved.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction equipment, in particular to a mobile recycled asphalt mixture cold mixing equipment and method for road construction. Background technique [0002] Asphalt mixture is a general term for mixtures made by mixing mineral aggregates and asphalt binders. According to the material composition and structure, it can be divided into continuous graded and discontinuously graded mixtures. According to the size of the nominal maximum particle size, it can be divided into extra-coarse type (nominal maximum particle size greater than 37.5mm), coarse-grained type (nominal maximum particle size 26.5mm or 31.5mm) , medium-grain type (nominal maximum particle size 16mm or 19mm), fine-grain type (nominal maximum particle size 9.5mm or 13.2mm), sand-grain type (nominal maximum particle size less than 9.5mm) asphalt mixture, according to the manufacturing process is divided into heat Mixed asphal...
