It is fixed.Embodiment described in the invention is only a part of the embodiment of the present invention, instead of all the embodiments, based on the present invention
In embodiment, those of ordinary skill in the art's every other implementation obtained without making creative work
Example, shall fall within the protection scope of the present invention.
Embodiment
As shown in Figure 1, a kind of super construction technology for gluing ultra-thin stress absorbing layer, includes the following steps: at disease early period
Managing --- slotting to existing cement concrete basal plane expansion joint ---, the later period formally constructs；Wherein:
Disease Processing early period: including to cement concrete basal plane fracture unit: the expansion joint for being greater than 5mm
The expansion joint less than 5mm can directly can be brushed with hairbrush, directly with the direct cementation of fissures of aqueous base joint grouting glue to basal plane injustice
Whole, low-lying place carries out leveling, and the levelling material of different models is selected according to levelling thickness；
Slot to existing cement concrete basal plane expansion joint: the depth of fluting is 2mm, then will hold stretching for slot successfully
Contracting seam carries out cementation of fissures processing, until base joint grouting glue demulsification after-contraction molding, anti-cracking cloth is posted on the expansion joint filled, in anticracking
Water shutoff item is carried out on cloth；
The later period formally constructs: cleaning cement pavement is clean to surface, and distribution vehicle sprays cement pavement sticking layer oil, micro-
Table paver vehicle paves on stress absorbing layer to Portland Cement Concrete Surface Course, demarcates before paving to the match ratio of mixture, determines
Correct match ratio.
Specific embodiment 1
The white of certain cities and counties changes black stress absorbing layer, and former cement and concrete pavement road surface is overlaying 4 centimeters of heated bitumen above
Then concrete road surface, the stress absorbing layer that Backing layer paves are stretched cement by the Disease Processing to cement basal plane early period
Contracting seam is slotted, the cementation of fissures, pastes anti-cracking cloth, does water shutoff item, is finally paved to the stress absorbing layer on the road surface.Since this tests
Road belongs to national highway, and vehicle flowrate is relatively large, so the quality requirement for the stress absorbing layer is very high, other in this area are white
Change black pavement spread is all thicker heated bitumen surface layer (add in one layer of paving in grain formula surface layer), therefore quality of materials comparison can
Know its effect.
Specific embodiment 2
The white of certain cities and counties changes black stress absorbing layer, and former road surface is cement concrete pavement, is overlaying 4 centimeters of heat drip above
Green concrete road surface, the stress absorbing layer that Backing layer paves, by the Disease Processing to cement basal plane early period, then to cement
Expansion joint is slotted, the cementation of fissures, pastes anti-cracking cloth, does water shutoff item, is finally paved to the stress absorbing layer on the road surface.Wherein there is one section
For the cement concrete pavement of bridge floor, and compared with the stress absorbing layer of the design of different specification around.
Specific embodiment 3
The white of certain cities and counties changes black stress absorbing layer, and former road surface is cement concrete pavement, is overlaying 4 centimeters of heat drip above
Green concrete road surface, the stress absorbing layer that Backing layer paves, by the Disease Processing to cement basal plane early period, then to cement
Expansion joint is slotted, the cementation of fissures, pastes anti-cracking cloth, does water shutoff item, is finally paved to the stress absorbing layer on the road surface.The test section is
One slope, difference of height is larger, to the more demanding of stress absorbing layer.
Stress absorbing layer in the present invention includes the Disease Processing of early period and the processing of anti-cracking cloth water shutoff item, formal to the later period
Pave stress absorbing layer, including Disease Processing whether in place, anti-cracking cloth water shutoff item whether according to the ratio strict control, the later period paves is
No no agglomeration, whether Mixture Ratio correct, and whether the thickness to pave up to standard etc..
The strong multiple emulsion composition principle of black room temperature speed is as follows: the strong multiple emulsion of black room temperature speed is using polymer water and milk
SBS aqueous emulsion, increasing stick toughening aqueous emulsion are added in the base of modified emulsifying asphalt and can make pitch for the modified mode of liquid
