Description
Technical field
The invention belongs to pavement construction material field, be related to a kind of environmental protection and economy type asphalt stabilized base course mixtures and
Preparation method.
Background technology
The semi-rigid type base based on cement stabilized macadam is used most of in the current high-grade highway construction in China, in reality
Use during semi-rigid type base will produce more contraction fissure, crack reflection to face layer causes surface cracking, influences
The performance on road, shortens the working life.
Flexbile base based on Asphalt Stabilized Macadam has the ability of good transmission load stress, while will not produce
Raw contraction fissure, it is ensured that the performance on road surface, but the cost of flexible asphalt and gravel stabilization base layer is relatively high, greatly
It is hindered to use and promote.
Coal liquefaction residue is the residue in coal liquefaction, will produce 30% or so according to ASSOCIATE STATISTICS coal liquefaction
Primary residue is not only the waste of resource and meeting if these residues are not subject to reasonably to abandon using and as waste
Certain environmental pollution is caused, especially under the overall background of energy-saving and emission-reduction, to resource adequately and reasonably using seeming particularly heavy
It wants.
Contain more asphaltene substance and oil, constitutive property and road asphalt studies on asphaltene in coal liquefaction residue
Component is similar to very much, if flexbile base cost will can simultaneously be solved its use in flexible asphalt and gravel stabilization base layer
The high and difficult two kinds of problems of residue.Therefore, coal liquefaction residue is utilized in Asphalt Stabilized Crushed Stone Basement material, develops one
The environment friendliness Asphalt Stabilized Crushed Stone Basement material of kind is particularly necessary.
Invention content
It is an object of the invention to overcome the above-mentioned prior art, it is broken to provide a kind of environmental protection and economy type Bituminous stabilized
Stone base mixture and preparation method thereof, the mixture and preparation method thereof is using coal liquefaction residue as raw material, economy and environmental protection
Property is preferable.
In order to achieve the above objectives, environmental protection and economy type asphalt stabilized base course mixtures of the present invention are by quality percentage
Than being prepared for the coal liquefaction residue of the gathering materials of 89%-95%, the miberal powder of the pitch of 3%-5%, 1%-3% and 1%-3%.
The nominal maximum aggregate size to gather materials is less than or equal to 31.5mm.
The mass ratio of coal liquefaction residue and miberal powder is 1：1.
The content of ash content is less than or equal to 30% in coal liquefaction residue.
The grain size of miberal powder is less than or equal to 0.6mm.
The preparation method of environmental protection and economy type asphalt stabilized base course mixtures of the present invention includes the following steps：By power
Profit require 1 weigh gather materials, pitch, miberal powder and coal liquefaction residue, coal liquefaction residue and miberal powder are dried and fine grinding, then passes through
Screen size is that the sieve of 0.075mm is sieved, and is then stirred coal liquefaction residue and gathering materials, adds miberal powder, stirring
After pitch is added, finally stir evenly, obtain environmental protection and economy type asphalt stabilized base course mixtures.
It is by the concrete operations that coal liquefaction residue and miberal powder are dried：Coal liquefaction residue and miberal powder are put into baking oven,
Dry 1h under conditions of 120 DEG C again.
By coal liquefaction residue and the mixing 90s that gathers materials, miberal powder is added, pitch is added after stirring 90s, finally stirring is equal
It is even, obtain environmental protection and economy type asphalt stabilized base course mixtures.
It finally stirs evenly, obtains mixing time during environmental protection and economy type asphalt stabilized base course mixtures and be more than etc.
In 180s.
The invention has the advantages that：
Environmental protection and economy type asphalt stabilized base course mixtures of the present invention by gathering materials, pitch, miberal powder and coal liquefaction
Residue forms, and the residue coal liquefaction residue in coal liquefaction is incorporated into Asphalt Stabilized Crushed Stone Basement material, is solved
The intractable problem of residue avoids the environmental pollution for arbitrarily abandoning and bringing, while reducing the cost of Asphalt Stabilized Crushed Stone Basement,
The popularization for being conducive to flexbile base solves the problems, such as Semi-rigid Base Reflective Crevice more serious in current road.In addition, making
During standby, it is only necessary to mix each raw material in sequence, first coal liquefaction residue need not be added in pitch
It is used again after modified pitch is made, prepares relatively simple, practical value height.Simultaneously after testing, the environmental protection and economy type pitch
The high-temperature behavior of stabilized macadam base mixture, cryogenic property, water stability are satisfied by code requirement, and oilstone is smaller, drip
Green dosage is relatively fewer, and cost reduces.
