Description
Technical field
The invention belongs to the Prevention Technique field of reflection cracking in a pavement.
Background technology
Composite pavement is the making asphalt flexible face thereon as rigid base using cement concrete slab
Layer, has the advantages that good endurance, bearing capacity are high, driving is comfortable, noise is small.But because cement concrete and pitch mix
The material of material has differences, and the elastic modelling quantity of cement concrete is typically 15 ~ 20 times of asphalt, causes the two in load
Stress is different with lower the showed stress of temperature stress effect, emergent property, under humiture change or traffic load
Crack is also easy to produce, and is extended to surface layer so that surface layer cracking, the crack on this surface layer is referred to as reflection crack, is semi-rigid pavement
One of endangered with the main roads of rigid pavement.
In order to prevent the appearance of reflection crack, since the sixties in last century, scholars and engineering circles personage are around anti-
Penetrate crack problem and expand substantial amounts of experimental study, and have been developed that various anti-anti-technology for delaying or preventing and treating reflection crack,
The counnter attack method for primarily now using includes：1. geotextiles and grid are overlayed as preventing and treating reflection crack layer；2. rubber drip is overlayed
Green grass or young crops-rubble separation layer is used as preventing and treating reflection crack layer.
The shortcoming of above two method is：1. the stretch-resistance intensity of geotextiles and grid generally only has 25 ~ 50kN/m,
Easily it is pulled off under tension state, reinforced action is not obvious, or even part geotextiles and GSZ be in work progress
It is pulled off, later stage anti crack performance is decreased obviously, does not reach the anti-minus effect of expection, and when construction joint is larger or cement concrete slab
Surface smoothness is not reached when requiring, the weak reinforcement material such as geotextiles and GSZ is in work progress easily by sharp rubble
Puncture, counnter attack performance is relatively low.2. rubber asphalt-rubble separation layer needs cast-in-place existing use at the construction field (site), the clean level of rubble,
Rubber asphalt spreading amount etc. can all produce considerable influence, quality to be difficult to control to interlaminar bonding performance and road surface counnter attack performance.
It is worth noting that, being continuously increased recently as traffic volume of highway and automobile shafts carrying capacity, overload and oversize transportation
Remain incessant after repeated prohibition, actually national each province and city major trunk roads have different degrees of overload, can be above-mentioned under the conditions of this Heavy Traffic
The anti-minus effect of two kinds of traditional counnter attack methods is worse, is extremely difficult to road with requiring.
The content of the invention
The invention is intended to provide that a kind of reinforcement effects are good, counnter attack performance is high, quality controllable suitable for Heavy Traffic condition
Compound anti-antistructure.
Patent formula：Suitable for the compound anti-antistructure of Heavy Traffic condition, it is arranged in cement concrete basic unit, wraps
High tensile material layer is included, and the seal adhesion layer that high tensile material layer entirety is wrapped up.
This patent has the beneficial effect that：The tensile strength of high tensile material layer 1. in the present invention（Laterally or longitudinally）It is high
It is not easy to break up to 200kN/m, with strong reinforced action；2. the extremely strong tensile strength of high tensile material causes that this is compound anti-
Antistructure has restrained deformation ability higher（I.e. elongation percentage is low）Even if microcrack occurs in early stage road surface, the anti-antistructure is same
Sample can limit further expanding for crack；3. seal adhesion layer adhesion and by the overall parcel of high tensile material layer, it is to avoid environment
In the contact high tensile material layer such as air, moisture, dirt, prevent high tensile material layer to be oxidized or be corroded, in addition, sealing
Adhesion layer has certain toughness, improves compound anti-antistructure and Lower and upper bounds surface layer（Upper interface refers to asphalt surface course, under
Boundary layer refers to cement concrete basic unit）Adhesive property.4. this compound anti-antistructure has saved existing in factory's batch micro operations
The field engineering time, quality does not receive road site operation ambient influnence to product in itself, improves product quality controllability.
Further, the melt temperature of high tensile material layer and seal adhesion layer is all higher than the melt temperature of asphalt surface course,
This compound anti-antistructure is prevented in work progress（The temperature of asphalt surface course is higher during construction）Rolling up, such as occurs in generation mutation
Song, depression, pit-hole etc..
Further, the high tensile material layer is stainless steel cloth or zinc-plated iron net or high-strength carbon fibre net or high-strength modeling
Material net, is respectively provided with high tensile characteristic, depending on actual conditions selection.
Further, the seal adhesion layer is HZ/ZD-4 contractings caulking material layer or anti-corrosion glue-line, selection HZ/ZD-4 contractings
Caulking material layer（Normal temperature is in a liquid state, and meets air curing）, can construct at normal temperatures first, without heating, i.e., with i.e. use, construction ten
Divide convenient, secondly, good fluidity under HZ/ZD-4 contracting caulking material normal temperature, accessibility is strong, the adhesiving effect with high tensile material layer
It is good；Again, compactness is high after the solidification of HZ/ZD-4 contractings caulking material, can effectively protect internal high tensile material layer, prevents high anti-
Draw material layer oxidation or corrode, it is notable that toughness is higher after the solidification of HZ/ZD-4 contractings caulking material, absorbs stress
Effect is preferable；Selection anti-corrosion glue-line, mobility is also higher during dope liquid, and the adhesiving effect with high tensile material layer is preferable,
Compactness and toughness are also higher after anti-corrosion adhesive curing.
Further, because the maximum temperature of asphalt is 210 DEG C（It is waste material higher than 210 DEG C）, high tensile material
The melt temperature of layer and seal adhesion layer is more than 230 DEG C, can avoid in Laying Asphalt Surface Course（It is made up of asphalt）Shi Fa
Raw mutation.
Present invention also offers a kind of application of the compound anti-antistructure suitable for Heavy Traffic condition.
Patent formula：A kind of application of compound anti-antistructure suitable for Heavy Traffic condition, will be above-mentioned compound anti-
Antistructure bottom surface and cement concrete base adhesive, then the Laying Asphalt Surface Course on compound anti-antistructure top surface.
Beneficial effect：Compound anti-antistructure is transported to scene after factory's manufacture is finished, and the compound anti-antistructure is straight
Connect and be bonded in cement concrete basic unit, then use asphalt surface course making, such counnter attack layer is compound without manufacturing at the construction field (site)
Quality does not receive road site operation ambient influnence to anti-antistructure in itself, and the quality unification of product is controllable；In addition, the compound counnter attack
Structural elongation is low, and restrained deformation is very competent, even if the initial stage produces microcrack also to limit the progressive of crack extending, anti-reversal
Fruit is preferably.
Further, compound anti-antistructure passes through polyurethane adhesive or epoxies cementitious matter or heated bitumen or high viscosity
Emulsified asphalt and cement concrete base adhesive.
Present invention also offers a kind of reinforcement effects are good, counnter attack performance is high, quality controllable suitable for Heavy Traffic condition
