Description
Technical field
The present invention relates to a kind of asphalt pavement structure that slows down city " heat island effect ", can effectively reduce the temperature of flexible pavement, reduce city air-conditioning power consumption in summer, alleviate urban electricity supply pressure, be suitable for " nice and cool road surface " construction demand of urban road.
Background technology
(0.85～1.09J/KgK), therefore, it very easily gathers heat on daytime in summer, produce higher pavement temperature because flexible pavement has less albedo (0.05～0.15) and bigger thermal capacitance; And in night, flexible pavement is discharged into a large amount of heats of being put aside in the air of near surface in the infrared radiation mode again, is the one of the main reasons that forms city " heat island effect ".Along with warming of global climate, the quickening of urbanization development speed, city " heat island effect " will be more outstanding.
At present, the main pavement technique method of slowing down city " heat island effect " both at home and abroad is: the albedo that 1) improves the road surface.That is: by at road surface brush, be coated with light-coloured coating, or in top course, add light building stones to improve the road surface albedo, reduce the absorption of flexible pavement, thereby reduce pavement temperature solar radiation; 2) flexible pavement of laying loose porous material.That is: lay the drainage road of macroporosity (＞20%) in urban road, loose porous road surface helps the evaporation of moisture in the road surface, thereby reduces road surface high temperature.But all there is certain deficiency in these two kinds of methods, and for example: the light road surface of high albedo can form strong reflection to visible light usually, reduction urban traffic marker line, even influence driver's eyesight.2004, a Japan day shop company (Nippo) developed a kind of grey (brightness index＜40) high albedo road coating, and remedied this defective well: it is 85% to the equal albedo of near-infrared popin, and only was 23% to the albedo of visible light.The road is found with test: after the spraying, the maximum temperature of flexible pavement coating is lower 15 ℃ than traditional asphalt road surface; Even at night, the coating temperature is also than low 2 ℃ of traditional asphalt road surface.Yet still there are the following problems for the new coating of day shop company: owing to exist a large amount of aerosol particles in the urban road air ambient, can absorb the long-wave radiation from road reflection; Simultaneously, roads such as building, pedestrian periphery object also can absorb a large amount of heat radiations, and therefore, the heat that is reflected by road surface coating does not turn back to the outer space, city, still can come out at night.In addition, the price of coating is more expensive, even also be that use in special place in the parking lot etc. in Japan.
And for the flexible pavement of loose porous property, in use, because obstruction space such as dust, foreign material and vehicular load effect cause the further compacting of road structure, the space is dwindled, cause road surface pervious function reduction, breakages such as crackle, hole groove appear in flexible pavement easily, and then cause Pavement Performance to reduce; Simultaneously, the comprehensive pavement performance on loose porous property road surface as mechanical strength etc., all reduces a lot than traditional asphalt road surface.
By 2003, the coverage scale of China's urban road has reached 7-15%, and the megalopolis then surpasses 20%.Owing to reasons such as price and industrialization maturations, at present, the Chinese city road is mainly flexible pavement, and city " heat island effect " problem will be more serious.How effectively to stop the solar radiation heat the gathering of flexible pavement, obtain more economical, technical method slows down " heat island effect " efficiently, to the China of energy scarcity, seems particularly important.
Utilize powder-modified bituminous material to obtain new physical function, existing big quantity research at home and abroad; But, by powder-modified blacktop to obtain road structure with gradient thermal conductivity, and then make flexible pavement have the one-way heat conduction function, the flexible pavement solar radiant heat is inducted into huge underground of heat capacity, still be in blank both at home and abroad, that is: " one-way heat conduction " principle is applied to the technical method of flexible pavement, does not still have corresponding patent both at home and abroad.The application of patent to improving the life of urban resident comfort level, particularly alleviates city air-conditioning power consumption in summer, saves national energy, has the excellent development prospect.
Summary of the invention
Technical problem:, the present invention proposes a kind of asphalt pavement structure of the alleviating urban heat island effect based on one-way heat conduction at the aggravation and the existing defective of traditional technology method of China's urban heat land effect.Typical road structure of the present invention by trace add cheaply, the micro-nano powder of homogeneity (thermal conductivity), different amounts (consumption) does not make the road surface have the one-way heat conduction function in the three layer construction of asphalt surface course; Utilize this function, the solar radiation heat can be delivered in the huge roadbed of thermal capacitance, make the road surface become " feeling nice and cool " type road surface in summer.
Technical scheme: the asphalt pavement structural layer of the alleviating urban heat island effect based on one-way heat conduction of the present invention is by two supercrusts of forming to sandwich construction with gradient thermal conductivity structure, and wherein, the thermal conductivity of outer surface layer is lower than the thermal conductivity of internal layer.
Described supercrust is to be the upper layer of 10～30w/mk, the first micro-nano powder modification by thermal conductivity, thermal conductivity is the middle surface layer of 50～90w/mk, the second micro-nano powder modification, and thermal conductivity is the supercrust with gradient thermal conductivity structure of the following surface layer composition of 100～140w/mk the 3rd micro-nano powder modification.
The thermal conductivity gradient-structure of the upper, middle and lower-ranking of described flexible pavement is by adding different amounts, homogeneity micro-nano powder acquisition.
Described first micro-nano powder, powder body material are at least a kind of in silica, alumina, the zinc oxide, and its addition is 10%～40% of a upper layer grating asphalt content.
Described second micro-nano powder, powder body material are carborundum, and addition is 5%～20% of a middle surface layer grating asphalt content.
Described second micro-nano powder is a graphite, and diameter of particle is 0.1～100 micron, and consumption is 1%～10% of a middle surface layer grating asphalt content.
Described the 3rd micro-nano powder, powder body material are graphite, its addition be following level join asphalt content 5%～15%.
The road structure operating principle of this one-way heat conduction can be described as: on daytime in summer, because following surface layer thermal conductivity is greater than middle surface layer, middle surface layer thermal conductivity is greater than upper layer, heat flow density is served as reasons little of macrostructure from upper layer to following surface layer, therefore, a large amount of radiations heat energies of gathering of upper layer are easy to be transferred to middle surface layer; In like manner, the heat of middle surface layer reception also is easy to be transferred to down surface layer.So the solar radiation heat that enters the road surface is imported into surface layer in the roadbed in a large number, and interlayer thermal conductivity gradient is big more, and the interlayer temperature difference is big greatly more, and the speed that the heat that upper layer absorbed transmits in roadbed is just fast more.And in night in summer, based on same up-small and down-big thermal conductivity gradient principle, most of heat that roadbed and roadbed bottom are gathered is difficult to be turned back to by the following surface layer of high heat conductance the upper layer of lower thermal conductivity again.Therefore, utilize structure of the present invention, can reduce flexible pavement high temperature by day, the heat that can avoid again being absorbed turned back in road surface and the air at night, make flexible pavement become " nice and cool road surface " in summer, from reaching the effect that reduces city " heat island effect ".The present invention has the advantage that construction is easy, cost is low easily in conjunction with conventional flexible pavement construction, maintenance and regeneration techniques.
Beneficial effect: in order to reduce or alleviate city " heat island effect ", at present, domestic and international major technique that adopts and principle are: the albedo that 1) improves the road surface; 2) flexible pavement of laying loose porous material.These two kinds of know-whies all exist significant disadvantages and deficiency.
Improve the deficiency of albedo technology:
1. easily driver's vision is caused stimulation, influence traffic safety.Though, grey (brightness index＜40) the high albedo road that shop company (Nippo) was developed in 2004 Japanese day can remedy " visual stimulus " defective well with coating, but, because the road surface can not be as " minute surface ", therefore, the near-infrared ripple that new coating reflected will be radiated road surfaces such as building on every side in " diffuse reflection " mode, can't " former road be returned " to space, extramural, city, so, it is effective to reducing pavement temperature, but to the contribution of alleviating " heat island effect " and little, because solar radiant heat has gone above the building around the road surface has been transferred on the road surface etc., promptly heat still accumulates near the road.
2. adopting the technology that is coated with brush applied coating is matrix with the resin usually, and cost is very high, and resin rolls through tire, is easy to and stripping, and durability is lower.
Lay the deficiency on loose porous road surface:
1. laying loose porous road surface, will be cost to sacrifice Pavement Performance.For example, the mechanical strength on loose road surface can not show a candle to the mechanical strength on traditional road surface of same process and compound.
2. do not have polarity owing to pitch, and the polarity of water is very big, therefore, flexible pavement ponding is easy to cause peeling off of asphalt membrane and building stones, makes flexible pavement occur breakages such as crackle, hole groove easily, and then causes Pavement Performance to reduce.
3. obstruction such as dust, foreign material space and vehicular load effect cause the further compacting of road structure, and the space is dwindled, and cause road surface pervious function reduction.
The present invention is by the thermal conductivity modification to pitch or bituminous mixture, and make supercrust form nonlinear gradient thermal conductivity distribution, that is: the supercrust heat conductivity value is the structure of " up-small and down-big ", makes the heat of solar radiation in the road surface " come in to be difficult for, go out difficulty "; The heat of coming in simultaneously, will be directed in the heat capacity huge roadbed and soil.Therefore, the present invention will have the advantage of following uniqueness:
1. the solar radiation heat is directed into the earth, and the supercrust structure of heat conductivity value " up-small and down-big " makes the heat that enters the earth be difficult to return on the flexible pavement, realizes real " feeling nice and cool " road surface.
2. can not form visual stimulus.Simultaneously and since employed powder and bituminous mixture all be mixed into one, therefore, avoided similar " coating stripping " problem.
3. micro-nano powder used in the present invention has bigger specific area, by the physical modification to asphalt pavement material, can make the intensity of bitumen base compound bigger simultaneously, mechanical performance is higher, can improve the pavement performance on road surface effectively.
4. " high value thermal conductivity powder " used in the present invention, as: graphite and carborundum; " intermediate value thermal conductivity powder ", as: silica, alumina, zinc oxide etc., all belong to the conventional raw material of industry, obtain easily throughout the country, it is also all very convenient to process, transport, construct; And employed " low value thermal conductivity powder " is industrial residue, and cost is low, belongs to resource and utilizes, can protect environment, energy conservation.Because graphite that relative price is higher or silicon carbide powder just trace add, use amount is few, thereby uses total cost lower, is suitable for the relevant construction of large, medium and small urban pavement.
5. technology of the present invention is simple, workable, and routine construction and maintenance technology that can the bound bitumen road surface carry out design and construction.

The powder addition manner is that micro-nano powder stirs with building stones earlier with behind the abundant mix of pitch with the breeze in the micro-nano powder displacement compound.
The unidirectional conduction explanation of solar radiation heat:
On daytime in summer, when the solar radiation heat enters into the upper layer of flexible pavement, because middle surface layer 5 thermal conductivities are greater than upper layer 4, thermal resistance is less, thus the heat that gathers of upper layer 4 be easy to be transmitted in surface layer 5, in like manner, because the thermal conductivity of following surface layer 6 is greater than middle surface layer 5, be that thermal resistance is littler, therefore, middle surface layer 5 also is transferred to down surface layer 6 easily from the heat that upper layer 4 obtains.Thus, solar radiation is introduced in the roadbed 7 to the heat of road upper layer 4.Therefore, this road structure has " heat absorption " function, the solar radiation heat can be transmitted in roadbed and the earth fully.
At night in summer, because road surface of the present invention has the thermal conductivity gradient-structure of " big down little ", when the heat that does not have in roadbed 7 and the following soil matrix to have spread is want by descending surface layer 6 when middle surface layer 5 and even upper layer 4 distribute, since from upper layer 4, the heat conductivity value of surface layer 5, upper layer 6 to distribute be the order of " ascending ", the thermal resistance maximum of upper layer 4, middle surface layer 5 takes second place, heat in the roadbed 7 is difficult to go out along the sequence delivery of surface layer 6, middle surface layer 5, upper layer 4 down, only has less heat can be transferred to upper layer 4 and enters in the air.Like this, at night in summer, the temperature of flexible pavement just can not raise again, can avoid the heat of solar radiation on daytime to return in the air again.Therefore, this road structure also has the function of " thermal insulation " or " envelope thermosphere ", forms " nice and cool road surface ".
In one cycle in daytime of summer; because blacktop 4,5,6 is kept heat all the time to roadbed and underground one-way heat conduction state; make that the temperature on asphalt road surface is lower generally; reduced the radiations heat energy in air 8; from reaching the purpose that reduces city " heat island effect "; simultaneously, also the stability of road pavement has protective effect, prolongs the application life on road surface.
Experimental example
In order to confirm the validity of this typical case's road surface structare layer, carried out laboratory experiment at Southeast China University's traffic institute road and bridge experiment chamber.This test mainly is the validity of checking one-way heat conduction supercrust structure, and with the contrast of plain asphalt road surface after performance difference.Experimental facilities mainly contains chamber, and variable-voltage power supply and temperature acquisition system are formed.Wherein around the chamber and bottom is made of heat-insulation material.Process of the test is, in two incubators, place modified asphalt concrete test specimen and plain asphalt concrete sample respectively, by the exposure intensity of control mercury vapor lamp and the wind speed on irradiation time and test specimen surface, simulation road surface radiation condition in summer contrasts this two groups of test specimen surface temperature change situations.
Fig. 4 has provided the test specimen after powder-modified and the surface temperature observation comparison diagram of common test specimen.As seen from Figure 4, the test specimen surface temperature in entire test after powder-modified is lower than the surface temperature of common test specimen always, and when the test specimen surface temperature reached balance, it is maximum that the temperature difference reaches.Test specimen surface cooling effect after this explanation is powder-modified is fine, has shown that this one-way heat conduction supercrust structure is effective.
