Abstract

The invention discloses an asphalt mixture taking red mud as filler and a preparation method thereof. The asphalt mixture comprises the following components in parts by weight: 30-80 parts of coarse aggregate, 20-70 parts of fine aggregate, 3-6 parts of asphalt and 3-6 parts of filler, wherein the filler is a mixture of limestone mineral powder and red mud in a weight ratio of (1-3):(1-3). The preparation method comprises the following steps: (1) drying and levigating the red mud, uniformly mixing with the limestone mineral powder according to the ratio, and preheating at 160-180 DEG C for later use; (2) after the coarse and fine aggregates are preheated at 160-180 DEG C, adding asphalt and stirring uniformly; and (3) adding the preheated filler into the mixture obtained in the step (2) and stirring uniformly. In the invention, industrial waste red mud is used as filler of the asphalt mixture, thus the waste is turned into wealth, the land occupation and environmental pollution are reduced, the material cost of asphalt mixture preparation can be lowered, and the pavement performance of the asphalt mixture can be improved; and the asphalt mixture deserves wide promotion and application.

Description

A kind of utilize red mud as asphalt of filler and preparation method thereof
Technical field:
The preparation method that the present invention relates to a kind of asphalt, particularly relates to a kind of utilize red mud as asphalt of filler and preparation method thereof, belongs to road engineering material and preparing technical field.
Background technology:
Red mud, also known as red soil, is extract the Al in bauxite through various physics and chemical technology in aluminum oxide production process2O3Red pureed solid waste remaining after composition.Show according to national statistics office data, China Al in 20132O3Annual production is 3769.6 ten thousand tons, increases by 10.3% than 2012, accounts for whole world Al2O3More than the 30% of total output.In current production technology, often producing 1 ton of aluminium oxide just has the red mud of 0.8～1.5 ton to produce, so flourishing prosperous oxidation pot industry, the increase year by year of red mud discharge capacity certainly will be caused, substantial amounts of red mud is stored up for a long time owing to not being fully utilized and process, is occupied a large amount of soil, consumes more stockyard and builds and maintenance management expense, and alkali waste polluted surface, underground water source, cause the heavy damage of natural ecological environment, directly endanger the physical and mental health of people.Therefore, how comprehensive control and utilize red mud, have become as one problem demanding prompt solution of aluminum oxide industry.
Along with the quick growth of China's economy, to the demand of transportation also in important component part as country's composite transport channel of continuous raising, urban road and each standard highway, socio-economic development plays very important effect.This is once rare opportunity for the development of road engineering material particularly asphalt, the filler of one of the basic composition material as asphalt, due to selectable of less types, and it is subject to the restriction of region factor, relatively costly, the big contaminated environment of dust, it would be highly desirable to have new packing to replace.And red mud is similar to the carrier performance in asphalt after simple processed, it it is a kind of Filler in Asphalt Concrete substitute preferably.Industrial residue red mud is used in asphaltic road-mix surface course, there is important economic benefit and social benefit, protection environment is also had great importance simultaneously, be the perfect adaptation of environmental protection and capital construction.
Summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, thering is provided a kind of utilizes red mud as asphalt of filler and preparation method thereof, by Industrial Solid Waste red mud is used in asphalt as filler, turn waste into wealth, reduce land seizure area and environmental pollution.
The present invention solves that technical problem is adopted the technical scheme that:
A kind of utilize red mud as the asphalt of filler, including coarse aggregate, fine aggregate, Colophonium and filler, in units of weight portion, the weight proportion of each component is respectively as follows: coarse aggregate 30～80 parts, fine aggregate 20～70 parts, Colophonium 3～6 parts, mineral powder filling materials 3～6 parts, wherein mineral powder filling materials is the mixture of limestone dust and red mud, and the weight proportion of the two is limestone dust: red mud=(1～3): (1～3).
The preparation method of asphalt recited above, it specifically comprises the following steps that
1. red mud is levigate 105 DEG C of drying, mix according to proportioning and limestone dust, both are standby as the filler of asphalt after mixing thoroughly, by filler pre-stand-by heat at 160～180 DEG C during use；
2. the mixing and stirring at 160～180 DEG C by coarse aggregate and fine aggregate, then according to the road asphalt that proportioning adds described weight portion is stirred for uniformly；
3. last being joined in the compound that step is 2. prepared by filler after preheating stirs, and obtains asphalt for road.
Red mud of the present invention is that aluminium industry extracts the industrial pollution garbage of discharge during aluminium oxide.Red mud is dried levigate process, and granularity meets the requirement in " standard specification for construction and acceptance of highway asphalt pavement " (JTGF40-2004) to filler, and outward appearance is lumpd without granule.
The present invention is had the beneficial effect that the filler utilizing industrial waste red mud as asphalt, it is possible not only to accomplish to turn waste into wealth, reduce land seizure area and environmental pollution, the material cost preparing asphalt can also be reduced, and without increasing new equipment when preparing asphalt, technique is simple, can also improve the pavement performance of asphalt simultaneously.
Detailed description of the invention:
Below in conjunction with specific embodiment, the present invention is made further explanation and description, but do not limit the present invention.
Embodiment 1:
Raw material: Colophonium adopts No. 70 substrate bi tumenf orr oads；Gather materials employing basalt, limestone dust and red mud all technical of thickness meets in " standard specification for construction and acceptance of highway asphalt pavement " (JTGF40 1) related request to filler.
Asphalt type: DAC-13, match ratio is in Table 1.
When wherein red mud and limestone dust are collectively as filler, mix ratio is 1:3, and the property indices of gained DAC-13 type asphalt is in Table 2.
Embodiment 2:
