Description
Technical field
The present invention relates to cold in ground surface material technical field more particularly to city Lv Dao, bus zone, tourist district's road
Mix type chromatic bitumen mixture and preparation method.
Background technology
With the rapid development of the national economy, the infrastructures such as highway road and urban road also stable development, people
For the chromaticity of urban road material, harmony, more stringent requirements are proposed.Get used to Baise road surface (cement of traditional dullness
Concrete road surface) and dark-coloured pavement (asphalt concrete pavement), a kind of novel Colorful Asphalt Pavement, which is increasingly becoming, improves people
The development trend of dull vision.Colorful Asphalt Pavement induces wagon flow effect, beautifying city, road improvement environment with it and improves row
The advantages that vehicle safety and be widely used in avenue, tourist attraction road, the green road in city and various turnings, speed limit, friendship
Pitch area.
Current color asphalt technology includes mainly three kinds.First, it is acted on by colloid mill together with pitch using pigment
It is used to prepare chromatic bitumen mixture after being prepared into color asphalt, there is costs for chromatic bitumen mixture prepared by this method
High, durability difference disadvantage.Second, the chromatic bitumen mixture for preparation of partly commonly gathering materials is substituted using gathering materials for dyeing, but
It is that chromatic bitumen mixture prepared by this scheme haves the shortcomings that color is single.Third, using outer addition inorganic color pigment
Method prepare chromatic bitumen mixture, chromatic bitumen mixture prepared by this method, which exists, bonds force difference, durability difference
Disadvantage.
Chromatic bitumen mixture is frequently used for the express zone such as city Lv Dao, intersection, turning crossing, such region
Often machine spreading, roll least convenient area, directly affect the construction quality of chromatic bitumen mixture, largely deposit
In the problem of compactness deficiency, cause the colored road surface porosity constructed excessive, accelerates under rainwater and appropriate load action
The destruction of colored road surface.In addition, there are expensive, organic modifiers and inorganic pigment are viscous for the best color asphalt technology of effect
The shortcomings of knot property is poor, high-temperature behavior is poor, this also constrains the development of this technology, and the cold mixing type color road based on color asphalt
The research in face is applied just less.
For when the generally existing in first three chromatic bitumen mixture preparation method the shortcomings that, consider green for city
The defect when express zone such as road, intersection, turning crossing in terms of chromatic bitumen mixture construction, the present invention propose a kind of cold
It mixes, the new type colorful asphalt of high-adhesion energy, high-durability, color duration length.
Invention content
In order to solve the above technical problems, the object of the present invention is to provide a kind of cold mixing type chromatic bitumen mixture and preparation sides
Method, ground surface material prepared by this method have the characteristics that cold mixing, high-adhesion energy, high-durability, color duration length.
The purpose of the present invention is realized by technical solution below：
A kind of cold mixing type chromatic bitumen mixture, including：Aromatic naphtha, rubber oil, Petropols, epoxy resin, modifying agent,
Plasticizer, diluent, diatomite, pigment, stabilizer, water, emulsifier, antifoaming agent, gather materials, filler, cement, waterborne curing agent and
Swelling agent.
A kind of preparation method of cold mixing type chromatic bitumen mixture, including：
Choose aromatic naphtha, rubber oil, Petropols, epoxy resin, modifying agent, plasticizer, diluent, diatomite, pigment
And stabilizer, and by the aromatic naphtha, rubber oil, Petropols, epoxy resin, modifying agent, plasticizer, diluent, diatom
Soil, pigment and stabilizer are 100 in mass ratio:10~15:20~40:10~20:5~10:5~10:2~6:10~15:15
~20:0.5~1 ratio is mixed, and chromatic bituminous cement is obtained；
Choose emulsifier, stabilizer and antifoaming agent, and by the emulsifier, stabilizer, antifoaming agent and the color asphalt
Ramming material is according to 80~100:0.5~1.0:1~5:0.2~0.6~100:80 ratio is mixed, and emulsification color asphalt is obtained
Cementitious matter；
Selection gathers materials, filler, cement, waterborne curing agent, swelling agent and emulsification chromatic bituminous cement, and by the collection
Material, filler, cement, waterborne curing agent, swelling agent and emulsification chromatic bituminous cement press 100:2~6:1~2:2~6:1~5:
10~15 ratio is mixed, and cold mixing type chromatic bitumen mixture is obtained.
Compared with prior art, one or more embodiments of the invention can have the following advantages that：
It is basic component (its effect is equal to the asphalitine in four big component of matrix pitch) with aromatic naphtha, passes through asphalt mixtures modified by epoxy resin
Fat carries out compound thickening to high aromatic oil simultaneously with Petropols two-component, and wherein Petropols are dispersed in aromatic naphtha,
The effect of enhancing aromatic naphtha itself glues toughness is played, epoxy resin is then by when preparing cold mixing type chromatic bitumen mixture
Time is reacted by being cured with waterborne curing agent, and the cured product of formation is the high binding material of thermosetting property, can interweave and run through
In aromatic naphtha matrix, and then greatly promote whole high temperature resistance and adhesive property.Modifying agent is primarily to promoted whole
The overall performance of body material, especially crack resistance at low-temperature.In order to improve point of the SBS modifier/SBR modifying agent in aromatic naphtha
Effect is dissipated, effectively modifying agent can be softened using rubber oil, and then improves the swelling reaction of modifying agent, enhances modified effect
Fruit.In addition, rubber oil itself also acts the effect of the oil in four big component of matrix pitch.Cold mixing type chromatic bitumen mixture
Intensity the pitch matrix, epoxy resin-cured product and the cement water that are mainly formed by various modified components and aromatic naphtha
Change product and the offer of organo-mineral complexing cementing material is provided, passes through the coordination of ratio and key component between this three
Control, form the network structure of intertexture symbiosis, can be effectively improved conventional emulsification asphalt and aggregate bond loosely, high and low temperature
The disadvantage of energy difference.In addition, diatomite is blended with color pigment, diatomaceous porosity characteristic and its good compatible with aromatic naphtha is utilized
Property can alleviate the shortcomings that inorganic pigment and aromatic naphtha bond force difference, to ensure that the resistance to stripping of color and luster during colored road surface is on active service
It falls.Emulsification chromatic bituminous cement proposed by the present invention has cold mixing, high-strength cohesive force, excellent flexibility, durability and supports
There is heat to mix drip for the significant advantages such as anti-high and low-temp destruction, Water Damage, stain resistant, prepared cold mixing type chromatic bitumen mixture
High-temperature behavior, cryogenic property, water stabilizing and the mechanical property of green mixture.
