The present invention is include at least the following beneficial effects:
The first, reach the pitch prill road face for needing to re-lay for pavement damage rank, by the bitumen layer in the face Jiu Dao and mix
Substrate surface is exposed in solidifying soil layer whole milling, from being successively laid with emulsified asphalt layer, heat-sink shell, asphalt pavement layer, pitch under
Road surface layer reflects away a large amount of radiant heat, and the heat of absorption quickly receives neutralizing by heat-sink shell, and the two, which combines, reduces entire paving
If road layer temperature elevated-levels, so that volume change degree is reduced, to extend the service life of road.
The second, in the hot environment in Africa, in addition airfield pavement is chronically under conditions of insolation, road face absorbs heat
More, temperature increases more, and heat absorption stick and fine sand is used to combine, rubber absorbs heat, and transmitting water supply, the thermal capacity of water is big, can be with
It is a large amount of to absorb heat, and temperature raising is small, adjusts the raised effect of temperature to have, avoids the volume expansion of heat-sink shell entirety
Excessively, and the temperature changes of other each layers is adjusted, extends the service life of asphalt roads.
Third, radiation cooling insulating moulding coating layer can reduce absorption radiant heat, and most of radiant heat is reflected away, thus
The amount that asphalt pavement absorbs heat is reduced, hollow ceramic case has heat-blocking action, can reduce heat absorption, to reduce pitch
The total amount of heat that road surface layer absorbs, so that it is excessive to avoid its temperature from increasing, asphalt pavement layer volume expansion deformation reduces.
Further advantage, target and feature of the invention will be partially reflected by the following instructions, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
Detailed description of the invention
Fig. 1 be one of technical solution of the invention repairing after Airport Asphalt longitudinal cross-section schematic diagram；
Fig. 2 is the detail view of the heat absorption stick of one of technical solution of the present invention.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
It should be noted that experimental method described in following embodiments is unless otherwise specified conventional method, institute
Reagent and material are stated, unless otherwise specified, is commercially obtained；In the description of the present invention, the orientation of term instruction
Or positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and simplification of the description, and
It is not that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore
It is not considered as limiting the invention.
As shown in Fig. 1~2, the present invention provides a kind of Airport Asphalt method for repairing and mending, comprising:
According to pitch prill road face evaluation result, the pitch prill road face for needing to re-lay is reached for pavement damage rank, it will be old
The bitumen layer and concrete layer whole milling in road face expose 1 surface of base；The repairing face Hou Dao is influenced to avoid the structure in the face Jiu Dao
Quality.
It is laid with emulsified asphalt on 1 surface of base, and is compacted form emulsified asphalt layer 2；Emulsified asphalt layer 2 plays connection bottom
Base 1 and upper one layer of heat-sink shell 3 relationship, reduce the degree that relatively transverse sliding occurs for heat-sink shell 3 and base 1.
Heat absorption stick is laid on 2 surface of emulsified asphalt layer and partial size is 4.5mm fine sand below, and is compacted form heat-sink shell 3,
Wherein, the heat absorption stick includes the rubber jar 31 of elliposoidal, the water being contained in the rubber jar 31, is arranged at intervals at the rubber
Multiple raised 32 on 31 outer surface of rubber shell, raised 32 material is rubber, and the spacing between two neighboring heat absorption stick is not
Greater than 5cm；In the hot environment in Africa, in addition airfield pavement is chronically under conditions of insolation, road face absorption heat is more, temperature
Degree raising is more, and heat absorption stick and fine sand is used to combine, and rubber absorbs heat, and transmitting water supply, the thermal capacity of water is big, can largely inhale
Heat is received, and temperature raising is small, adjusts the raised effect of temperature to have, avoid the volume expansion of the entirety of heat-sink shell 3 excessive,
And the temperature change of other each layers is adjusted, extend the service life of asphalt roads.
It is laid with heat-barrier material on 3 surface of heat-sink shell, and is compacted form asphalt pavement layer 4, wherein the system of the heat-barrier material
Preparation Method specifically: by Li Qing Stone-bridge and ceramic bead be in mass ratio 1:0.15 be uniformly mixed to get heat-barrier material, the ceramic bead
Including hollow ceramic case and the radiation cooling insulating moulding coating layer for being laid in the ceramic case outer surface.Radiation cooling insulating moulding coating
Layer can reduce absorption radiant heat, and most of radiant heat is reflected away, so that the amount that asphalt pavement absorbs heat is reduced, it is hollow
Ceramic case has heat-blocking action, can reduce heat absorption, so that the total amount of heat of the absorption of asphalt pavement layer 4 is reduced, to avoid
Its temperature increases excessive, 4 volume expansion of asphalt pavement layer deformation reduction.
In the above-mentioned technical solutions, the pitch prill road face for needing to re-lay is reached for pavement damage rank, by the face Jiu Dao
Bitumen layer and concrete layer whole milling, expose 1 surface of base, from be successively laid under emulsified asphalt layer 2, heat-sink shell 3,
Asphalt pavement layer 4, asphalt pavement layer 4 reflect away a large amount of radiant heat, and the heat of absorption quickly receives neutralizing by heat-sink shell 3,
The two is in conjunction with the temperature elevated-levels for reducing the road layer being entirely laid with, so that volume change degree is reduced, to extend road
Service life.
In another technical solution, the long axis of the rubber jar 31 and the length of short axle are respectively 8cm and 2cm.It avoids
31 volume of rubber jar is excessive and is easy to be squeezed and broken when being compacted construction.
In another technical solution, the radius of the ceramic case is 5mm.It can be easier to be uniformly mixed with Li Qing Stone-bridge.
In another technical solution, emulsified asphalt layer 2, heat-sink shell 3, asphalt pavement layer 4 thickness be respectively 5cm, 3~
5cm, 15~18cm.Under the premise of meeting road surface structure performance, heat-sink shell 3 is made to absorb the ability and asphalt pavement of heat
The matching degree of the after-heat of 4 transmitting of layer is more excellent, and overall volume degrees of expansion is smaller after absorbing heat.
In another technical solution, plastic foam is filled in the ceramic case.The suction of heat can be further reduced
It receives.
It is located at the part interval other than described raised 32 in another technical solution, on 31 outer surface of rubber jar to set
There are multiple heat-conducting silica gel sheets.The transmitting effect that heat can be further strengthened, transfers heat in rubber jar 31 in water.
