Embodiment Construction

[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0015] Taking AC-16 iron tailings asphalt mixture as an example, the specific operation steps are as follows:

[0016] (1) Determine the gradation.

[0017] The gradation of coarse aggregate is taken according to the current standard, and iron tailings are used as fine aggregate. According to the experiment, coarse aggregate: iron tailings: lime=61:38:1.

[0018] (2) Make a Marshall specimen.

[0019] Calculate the asphalt mixture gradation according to the percentage of coarse and fine aggregates and the composition of coarse and fine aggregates, and make Marshall test pieces according to the gradation. The Marshall size meets the requirements of diameter 101.6±0.2mm and height 63.5±1.3.

[0020] (3) Determine the optimum oil-stone ratio.

[0021] According to the asphalt dosage range recommended by the specific...

Abstract

An iron tailing sand asphalt mixture belongs to the technical field of immobile buildings and roads of the E part of international patent classification (IPC). The mixture is characterized in that traditional coarse aggregates are used as a framework, iron tailing sand is used as a filler, a little lime is added as an additive, an optimal asphalt-aggregate ratio is determined through experiments, and a novel asphalt mixture is prepared. The effects and benefits of the mixture of the invention are that the using amount of grit in road construction is decreased; comprehensive recovery and recycle of iron tailings are realized; the comprehensive recovery and utilization of tailing resources not only can make full use of mineral resources, expand the utilization scope of mineral resources, prolong the mine service length, but also can treat pollution and protect ecology.

Description

technical field [0001] The invention belongs to the technical field of fixed building roads in Part E of the International Patent Classification IPC, and relates to the related problems of asphalt mixture in road engineering, and specifically relates to the preparation of a new type of iron tailing sand by applying iron tailing sand to asphalt pavement Asphalt. Background technique [0002] Tailings are the waste after mineral processing and are the main component of industrial solid waste. There are more than 8,000 state-owned mines and more than 110,000 township collective mines in China, with a stockpile of nearly 5 billion tons of tailings and an annual discharge of more than 500 million tons of tailings. At present, the comprehensive utilization rate of tailings in my country is only 7%, and the amount of iron tailings stockpiled is as high as more than one billion tons, accounting for nearly 1 / 3 of the total tailings stockpile. On the other hand, with the development...
