Abstract

The invention relates to the technical field of preparation of asphalt concrete based on retreated steel slag, in particular to a preparation method of asphalt concrete based on retreated steel slag, which comprises the steps of drying, screening, weighing and mixing, stirring, discharging and the like. The central control unit automatically calculates the weights of the retreated steel slag, the mineral aggregate and the asphalt according to the proportion, controls the screening unit to screen out the retreated steel slag and the mineral aggregate with the required particle size, and mixes the retreated steel slag and the mineral aggregate meeting the weight requirement of the proportion and then enters the stirring device; the depth detection sensor arranged in the stirring device detects the height of a material in the stirring tank in real time and feeds back the height to the central control unit, and the central control unit judges whether the compactness meets the standard by calculating the height ratio and adjusts the compactness by selecting a mode of adjusting the rotating speed of the stirring rod, the stirring time or adding other materials. The preparation efficiency of the steel slag asphalt concrete and the shipment quality of the steel slag asphalt concrete are improved.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete preparation from reprocessed steel slag, in particular to a method for preparing asphalt concrete based on reprocessed steel slag. Background technique [0002] Reprocessed steel slag is steel slag particles after removing free calcium oxide in steel slag. By replacing all or part of the stone in ordinary stone concrete with reprocessed steel slag and adding it to asphalt, steel slag asphalt concrete is prepared. Steel slag asphalt concrete is relatively For ordinary stone asphalt concrete, it can significantly improve the stability, low temperature crack resistance and durability of asphalt concrete. [0003] At present, in the preparation process of steel slag asphalt concrete, technicians usually need to calculate the weight of reprocessed steel slag, stone, asphalt and additives according to the ratio before proceeding to the subsequent process. The preparation process cannot be autom...
