Preparation method of high-permeability emulsified asphalt concrete

Abstract

The invention provides a preparation method of high-permeability emulsified asphalt concrete. A stirring mechanism, a guiding auxiliary mechanism, a screening mechanism and a bottom plate are included; the stirring mechanism and the screening mechanism are respectively mounted on the bottom plate, the guiding auxiliary mechanism is arranged on the opposite side of the stirring mechanism, and the guiding auxiliary mechanism is mounted on the bottom plate. The problems that a stirring device is difficult to clean during preparation and stirring of existing asphalt concrete, the asphalt concrete exists on the surface of the stirring device, the heavy and dry asphalt concrete exists on the surface after repeated use, the mechanical property of stirring is reduced, the prepared asphalt concrete material cannot be fully mixed, the preparation quality of the asphalt concrete is influenced, and stones for preparing the asphalt concrete are not screened, so that large-grain stones are inevitably doped in the stones, and the preparation quality of the asphalt concrete is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to a method for preparing high-permeability emulsified asphalt concrete. Background technique [0002] Emulsified asphalt is the liquid asphalt produced by asphalt and emulsifier under the action of certain process; emulsified asphalt is usually the road asphalt used at high temperature, which is diffused into water and liquefied by mechanical stirring and chemical stabilization. It can be used as a road construction material with very low viscosity and good fluidity at room temperature; it can be used at room temperature, and it can also be used with cold and damp stones; it can be made into high-permeability emulsified asphalt concrete by mixing; [0003] Nowadays, it is difficult to clean the mixing device when making asphalt concrete, resulting in asphalt concrete on the surface of the mixing device. Asphalt concrete materials cannot be fully mixed, which affects the pr...

Problems solved by technology

[0003] Nowadays, it is difficult to clean the mixing device when making asphalt concrete, resulting in asphalt concrete on the surface of the mixing device. Asphalt concrete materials cannot be fully mixed, which affects the preparation quality of asphalt concrete, and the stone materials for preparing asphalt concrete have not been screened, resulting in the inevitable mixing of large-grained stone materials in the stone materials, thereby affecting the preparation quality of asphalt concrete; for this reason, the present invention Provided is a method for preparing high-permeability emulsified asphalt concrete
