Description
Technical field
The present invention relates to ground surface material technical field, particularly relate to city Lv Dao, bus zone, cold in tourist district's road
Mix type chromatic bitumen mixture and preparation method.
Background technology
With developing rapidly of national economy, the capital construction such as highway road and urban road also stable development, people
Chromaticity, harmony for urban road material are had higher requirement.Get used to road surface, Baise (cement of tradition dullness
Concrete road surface) and dark-coloured pavement (asphalt concrete pavement), a kind of novel Colorful Asphalt Pavement is increasingly becoming and improves people
The development trend of dull vision.Colorful Asphalt Pavement is induced wagon flow effect, beautifying city, road improvement environment with it and improves row
The advantages such as car security and be widely used in avenue, tourist attraction road, green road, city and various turning, speed limit, friendship
Fork area.
Current color asphalt technology mainly includes three kinds.First, use pigment through colloid mill effect together with pitch
For preparing chromatic bitumen mixture after being prepared as color asphalt, chromatic bitumen mixture prepared by this method also exists cost
High, the shortcoming of poor durability.Second, use dyeing gather materials Substitute For Partial commonly gather materials preparation chromatic bitumen mixture, but
It is that chromatic bitumen mixture prepared by this scheme exists the single shortcoming of color.3rd, use outer interpolation inorganic color pigment
Method prepare chromatic bitumen mixture, there is cohesive force difference, poor durability in chromatic bitumen mixture prepared by this method
Shortcoming.
Chromatic bitumen mixture is frequently used for the express zone such as city Lv Dao, intersection, turning crossing, such region
Being often machine spreading, rolling least convenient area, directly affects the construction quality of chromatic bitumen mixture, major part is deposited
In the problem that compactness is not enough, cause the colored road surface porosity constructed excessive, accelerate under rainwater and suitable load action
The destruction of colored road surface.Glue additionally, the best color asphalt technology of effect exists expensive, organic modifiers with inorganic pigment
The knot property shortcoming such as difference, high-temperature behavior difference, this also constrains the development of this technology, and based on the cold mixing type color road of color asphalt
The research application in face is just less.
For when the shortcoming generally existing in first three chromatic bitumen mixture preparation method, consider for city green
Defect in terms of chromatic bitumen mixture construction during the express zone such as road, intersection, turning crossing, the present invention proposes a kind of cold
Mix, the new type colorful asphalt of high-adhesion energy, high-durability, color duration length.
Content of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of cold mixing type chromatic bitumen mixture and preparation side
Method, ground surface material prepared by the method has cold mixing, high-adhesion energy, high-durability, the feature of color duration length.
The purpose of the present invention is realized by following technical scheme：

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 described 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 mixes, and obtains chromatic bituminous cement；
Choose emulsifying agent, stabilizer and defoamer, and by described emulsifying agent, stabilizer, defoamer and described color asphalt
Ramming material is according to 80～100:0.5～1.0:1～5:0.2～0.6～100:The ratio of 80 mixes, and obtains emulsifying color asphalt
Cementitious matter；
Choose gather materials, filler, cement, waterborne curing agent, swelling agent and emulsification chromatic bituminous cement, and by described collection
Material, filler, cement, waterborne curing agent, swelling agent and emulsification chromatic bituminous cement press 100:2～6:1～2:2～6:1～5:
The ratio of 10～15 mixes, and obtains cold mixing type chromatic bitumen mixture.
Compared with prior art, one or more embodiments of the invention can have the advantage that：
Based on aromatic naphtha, component (its effect is equal to the asphalitine in the big component of matrix pitch four), passes through asphalt mixtures modified by epoxy resin
Fat carries out compound thickening with Petropols double-component simultaneously to high aromatic oil, and wherein Petropols are dispersed in aromatic naphtha,
Playing and strengthening effect that aromatic naphtha self glues toughness, epoxy resin is then by when preparing cold mixing type chromatic bitumen mixture
Wait by with waterborne curing agent generation curing reaction, the cured product of formation is thermosetting height binding material, can interweave and run through
It in aromatic naphtha matrix, and then is greatly promoted overall resistance to elevated temperatures and adhesive property.Modifying agent is primarily to promote whole
The overall performance of body material, especially crack resistance at low-temperature.In order to improve SBS modifier/SBR modifying agent in aromatic naphtha point
Dissipate effect, use rubber oil effectively can soften modifying agent, and then improve the swelling reaction of modifying agent, strengthen modification effect
Really.In addition, rubber oil itself also acts the effect that the oil in the big component of matrix pitch four divides.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
Changing the organo-mineral complexing cementing material that formed of product provides, the coordination of passing ratio and key component between this three
Control, define the network structure of intertexture symbiosis, conventional emulsification pitch can be effectively improved with gather materials bonding loosely, high and low temperature
The shortcoming of energy difference.Separately, diatomite and color pigment are blended, and utilize diatomaceous porosity characteristic and well compatible with aromatic naphtha thereof
Property can alleviate the shortcoming of inorganic pigment and aromatic naphtha cohesive force difference, thus ensure that colored road surface be on active service during the resistance to stripping of color and luster
Fall.The emulsification chromatic bituminous cement that the present invention proposes has cold mixing, high-strength cohesive force, excellent pliability, durability and supports
The significant advantages such as anti-high and low-temp destruction, Water Damage, stain resistant, prepared cold mixing type chromatic bitumen mixture has heat and mixes drip
The high-temperature behavior of blue or green compound, cryogenic property, water stabilizing and mechanical property.
