Description
Technical Field
The invention relates to the technical field of asphalt, in particular to an interlayer binder and application thereof.
Background
The composite pavement is formed by modifying a cement concrete pavement and paving asphalt concrete, so that the original rigid concrete pavement (grey white) is modified into an asphalt concrete flexible pavement (black), which is commonly called 'white to black'. The 'white to black' technology of the old cement concrete pavement has the characteristics of excellent pavement performance of the asphalt concrete pavement and high strength of the old cement concrete pavement, and is widely applied to reconstruction projects of the old concrete pavement.
At present, the construction and maintenance process of changing white into black on the composite pavement is widely applied. Such composite pavements are used in large numbers on roadways such as squares, airports, factories, school districts and the like. However, the viscoelastic characteristics of asphalt concrete are easy to form rutting and hugging phenomena, and moreover, the asphalt layer is additionally paved on the cement pavement, so that the interlayer shear stress and the surface layer stress are increased, and the damage is easy to occur; when the surface layer is subjected to a large horizontal load, fatigue cracks are easy to appear due to small interlayer bonding force, and shearing damage is formed. Meanwhile, the design thickness of the added layer is small easily caused by small interlayer shear stress and plate bottom bending tensile stress, so that the composite pavement is easy to damage.
At present, the interlayer adhesive belongs to Japanese epoxy resin with better test effect, but the material cost is too high, the interlayer adhesive is mostly used for bridge deck pavement, and needs to be explored when being used for common roads with low cost.
Disclosure of Invention
The present invention has been made to solve the above problems, and an object of the present invention is to provide an interlayer adhesive which has a good adhesion effect and is low in cost.
In order to achieve the purpose, the invention adopts the following technical scheme:
an interlayer adhesive is characterized by comprising the following components in parts by weight:
matrix asphalt as basic adhesive 440-460 weight portions;
440 portions and 460 portions of tap water;
spraying 15-20 parts of quick-setting anionic asphalt emulsifier;
15-18 parts of modifier SBR styrene-butadiene latex KZW-R65 type:
60-80 parts of self-emulsifying waterborne epoxy resin HY-R;
1-1.5 parts of a stabilizer;
1-1.5 parts of a defoaming agent.
Further: comprises the following components in parts by weight:
450 parts of matrix asphalt serving as a basic binder;
450 parts of tap water;

and 1 part of a defoaming agent.
In another aspect, an interlaminar binder as described above is used in paving asphalt.
Furthermore, the interlayer binder is sprayed on a cement pavement, and then a surface layer asphalt mixture is paved.
Further, the amount of the interlayer binder is as follows by weight: 0.4-0.6 Kg/m2。

Detailed Description
Example 1
An interlayer adhesive comprising, in parts by weight:
matrix asphalt as basic adhesive 440-460 weight portions;
440 portions and 460 portions of tap water;
spraying 15-20 parts of quick-setting anionic asphalt emulsifier;
15-18 parts of modifier SBR styrene-butadiene latex KZW-R65 type:
60-80 parts of self-emulsifying waterborne epoxy resin HY-R;
1-1.5 parts of a stabilizer;
1-1.5 parts of a defoaming agent.
Preferably (preferred values), the interlayer adhesive comprises, in parts by weight:
450 parts of matrix asphalt serving as a basic binder;
450 parts of tap water;
spraying 15 parts of quick-setting anionic asphalt emulsifier;
15 parts of a modifier SBR styrene-butadiene latex KZW-R65 type:
68 parts of self-emulsifying water-based epoxy resin HY-R;
1 part of a stabilizer;
and 1 part of a defoaming agent.
Example 2
Use of an interlayer binder as described in example 1 for paving asphalt mixes including but not limited to SMA-13, AC-13. Wherein the interlayer binder is sprayed on the cement pavement before paving the asphalt mixture.
The dosage of the interlayer adhesive is as follows according to the parts by weight: 0.4-0.6 Kg/m2.
Asphalt is selected as a basic binder, waterborne epoxy resin, an emulsifier and a modifier in proper proportion are prepared, meanwhile, a stabilizer with controllable performance is added, and the synthesized interlayer binder is sprayed on cement concrete by adopting a penetration anchoring method. After the high-temperature asphalt mixture is paved on the epoxy resin, the adhesive can be fully solidified under the high-temperature condition (100-130 ℃), and meanwhile, because the epoxy resin is a thermosetting material, the heat of the paved asphalt mixture can promote the hardening of the resin, so that the performance of the asphalt mixture can be exerted more quickly, and the interlayer adhesion effect of the inorganic layer and the organic layer is accelerated. Therefore, the research uses a mutual solution curing method to combine the prepared interlayer binder to make the lower cement concrete layer and the upper asphalt pavement layer tightly, and enhances the overall continuity between the cement concrete base layer and the asphalt pavement organic layer, thereby avoiding the problems of interlayer stripping and surface layer moving.
The shear strength of the preferred interlayer adhesive (preferred values in example 1, hereinafter referred to as "aqueous epoxy modified emulsified asphalt adhesive") is compared to the shear strength of other adhesives after use, as detailed in table one and fig. 1:
table one:
test data show that the single-use water-based epoxy resin (water-based epoxy adhesive) has good bonding effect but high cost. The effect of the preferred interlayer adhesive (the waterborne epoxy modified emulsified asphalt adhesive) is close to that of a single waterborne epoxy resin, but the material cost can be greatly reduced.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, and all technical solutions belonging to the principle of the present invention belong to the protection scope of the present invention. Modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
