Description
Technical field
The present invention is a kind of material that is used for the tunnel sheet pavement maintenance, and especially a kind of maintenance of surface mixing material that solves organic fire-resisting and environmental issue belongs to the technical field that the asphalt road surface material is made.
Background technology
1. tunnel road surface development trend
Because it is shorter that China builds the history of large-scale vcehicular tunnel, China is relatively weaker to the research of tunnel road surface structure and material, and tunnel road surface adopts cement concrete pavement mostly, and structural shape is single.On the one hand be because cement concrete pavement intensity height, work-ing life are longer, relatively meet the needs that should not often construct in the tunnel, and the road surface be of light color, driving is visual high; Then be that major part needs import, the cost height because the fire resistance of cement concrete pavement is relatively good, and high-quality asphalt output is less on the other hand.Simultaneously, the nineties in 20th century of presence of fire once in being grown up in the tunnel in Europe for security consideration, impels people more to select cement concrete pavement for use.
But there is seam in cement concrete pavement, and surface irregularity causes vehicle pitching, and comfortableness is poor, and is long in time limit, shortcomings such as maintenance difficult; Wearing no resistance of cement pavement, surperficial cling property is relatively poor, often causes the traffic accident in the tunnel.Cement concrete pavement in the tunnel is under dampness according to surveying and determination, and its frictional coefficient only is 40% under the drying regime, only is 25% of bituminous concrete pavement; The tunnel is the tubular structure of relative closure owing to grow up, and the noise in the tunnel will be far above the noise outside the tunnel, and noise can produce resonance, superposition phenomenon in the tunnel, make that noise is bigger in the tunnel, and in the tunnel noise time length longer, be difficult for to dissipate, noise effect the running environment in tunnel.In order to improve surperficial sliding resistance and driving comfort, reduce noise, overlay bituminous concrete surface layer or establish bituminous concrete pavement at former cement concrete pavement sometimes at new built tunnel middle berth.
Great majority are cement concrete pavement in the domestic tunnel road surface of building in early days, but, in recent years along with the progress of science and technology, the development of operating technique and the development of asphalt flame-retardant technology, make the fire performance of bituminous concrete that significant progress arranged, add people to the improving constantly of driving comfort requirement in the tunnel, bituminous concrete pavement is favored by people again gradually.Begun to have the part tunnel of growing up to begin to adopt bituminous concrete pavement after calendar year 2001, the long 5300m in Yanmen Guan tunnel that opened in 2003 has adopted bituminous concrete pavement, for the application of bituminous concrete pavement in Super Long Tunnel accumulated experience.According to investigations, external tunnel road surface extensively adopts bituminous pavement.The European most of national and U.S. mainly adopts bituminous concrete pavement in the tunnel, all adopted the asphalt pavement structure form as the Austrian Arberg tunnel of the long tunnel, Austrian Toon of Italian Blanc tunnel, the 6.4km of 16km length, 14km length, the Switzerland St.Gotthard Tunnel of 17km length etc.German, Japanese tunnel road surface generally adopts the cast asphalt concrete structural shape, for sliding resistance and the brightness that improves the road surface, go back spreading one deck on the cast asphalt concrete surface and calcine white flint, make the functions of use on its road surface good, illuminating value is good, prolong work-ing life, is a kind of comparatively ideal tunnel road surface structural shape.
In order to reach antiskid, noise reduction, comfortable, competent requirement, tunnel sheet pavement is usually selected SMA (stone mastic asphalt) road surface for use.The gap-graded mix making that this kind road surface is made up of pitch, fiber stabilizer, breeze and a spot of fine aggregate forms, and has characteristics such as excellent high-temperature stability (anti-rut performance), weather resistance (comprising water stability, resistance to fatigue and ageing resistance), surperficial sliding resistance, low noise.But, the general bituminous pavement of SMA pavement asphalt amount ratio is high more than 1%, and the flammable lignin fibre of admixture about 0.3% (with gathering materials weight ratio) is as stablizer, when the tunnel sheet pavement presence of fire is burnt, pitch and lignin fibre all can play combustion-supporting effect, increase the difficulty of tunnel fire hazard rescue, caused bigger loss.And general fire retardant can produce a large amount of smog and toxic gas under the pyritous environment, not only stoped rescue work to be carried out, the environment of having gone back severe contamination.This shows that tunnel road surface adopts bituminous pavement to become a kind of development trend, the problems such as bituminous pavement burning when tunnel fire hazard, environmental protection, maintenance that how to prevent need further research.
2. tunnel sheet pavement behaviour in service and fire safety evaluating
Under the special working environment such as underlying strength height, circumstance of temperature difference are little because tunnel road surface is in, humidity is big, canalized traffic is strict, acceleration and deceleration are frequent, make the pavement structure strained condition different with prevailing roadway, it is more serious to cause tunnel road surface to destroy, and has had a strong impact on the work-ing life of tunnel road surface and driver and conductor's comfortableness.China has faced the management work of consequent maintenance of surface after large-scale road construction, maintenance is transferred at the center of work, reconstruction is safeguarded and improve existing road surface, and tunnel road surface also faces same problem.
According to external generalized case, the asphalt pavement of highway back that is delivered for use is long then about ten years, and is short then promptly need keep in repair cover once in 5 or six years, second advanced then shorter with the maintenance cycle inferior grade road surface.In China, because Expressway Asphalt surface layer material therefor is wide in variety, strict, every layer all has different construction. and China motorway construction crew one is to lack experience, the 2nd, construction level is uneven, it is generally shorter to add the construction period, it is more to rob worker's phenomenon, also there were significant differences to have caused the construction quality in the different highway sections of same motorway, most of asphalt pavement of highway will occur in various degree breakage in 2～3 years being open to traffic, and use properties and service level are unsatisfactory.On the other hand and since behind some highway open to traffic of China the volume of traffic increase rapidly, the phenomenon that transfinites seriously and the influence of factor such as weather precipitation, more serious early damage has appearred in many road surfaces, makes maintenance work more shift to an earlier date.The motorway of China is early stage used 20 surplus year, therefore, highway division focus from now on certainly will turn to the maintenance on old road from the construction on new road.Maintenance of surface is for having fundamental influence the work-ing life of road, and along with the increase of mileage open to traffic and the raising of travel speed, this effect will be more obvious also.Economically developed country, greatly develop high-grade highway on the one hand, make great efforts to improve the rate of mating formation of land-service road on the other hand, attach great importance to the regular maintenance and the maintenance that have paved simultaneously, make it can keep good pavement performance and conveying efficiency, to prolong the work-ing life of road always.
The tunnel is the important component part of motorway, and the throat of motorway highway often.Large tunnel is interior because relative closure, tunnel fire hazard not only causes the serious breaking-up of tunnel facility and tunnel structure, causes short then a couple of days, and long then tens of skies even the road traffic of longer time interrupt, life, property safety that also can the serious threat people cause inestimable financial loss.In case presence of fire in the tunnel, a large amount of cigarettes, heat are difficult for eliminating, and is full of smoke in the hole, and illumination destroys, and visibility meter descends and with high temperature and poison gas, brings very big difficulty with rescuing for safe escape.Simultaneously, enter the tunnel by the up vehicle that comes of the express lane outside the tunnel after, the transverse section diminishes, spaces of vehicles shortens, the driving visual field narrows down.If car accident takes place in the front, the officer on the car of back is difficult for finding, thereby causes a large amount of vehicles obstructions, the development of aggravation fire.Bituminous concrete tunnel road surface particularly, bituminous material be owing to itself have tangible combustibility, and produce a large amount of smog when burning, will produce great harm to personnel safety.In recent years, owing to the major casualties that the fire in the domestic and international large tunnel causes, the fire prevention of large tunnel is taken precautions against natural calamities be subjected to generally paying attention to, this also becomes promotes the huge obstacle that tunnel sheet pavement must be crossed over.
The survey showed that, and the own characteristic of tunnel fire hazard also causes its destructiveness more much bigger than common buildings fire.Fire is in case take place, just reach very high temperature in very short time, make personnel be difficult to rapid escape, bituminous pavement, the hole wall of tunnel internal of can not only igniting repaiied, and, cause the bearing capacity reduction of structure or completely lose destruction tunnel water proofing system the huge damage of lining cutting generation, cause tunnel percolating water in various degree, so that influence the normal operation in tunnel; The a large amount of toxic smogs that produce during fire reduce the visibility meter in the tunnel, the influence person of going into and the escape of vehicle and carrying out of rescue work.Thereby, large-scale tunnel fire hazard generally takes place, all can cause a large amount of loss of life and personal injury and property damage.How, reduce the generation of tunnel fire hazard as far as possible, select rational pavement structure and material, make it have antiskid, flame retardant properties has great importance according to the tunnel fire hazard accident characteristic.
3. the application on flame-retardant pitch road surface
Fire retardant is that a class can stop material to ignite or suppresses the auxiliary agent of heat propagation, can be divided into addition type and response type two classes according to its using method.In the tunnel fire hazard process, at first fusion of pitch, drippage, trickling then are bead burning,, trickling unrestrained by the incendiary bead again, cause fire spreading to enlarge, and lead to fire.Asphalt fuel combustion is the physical and chemical process of a heat release, decomposition, decomposites hydrogen, methane, benzene and alkanes inflammable gas in the burning.These burning of gass have further been accelerated the bituminous thermolysis again.So that the characteristics of pitch fire are the oncoming force is violent, expansion is fast, scope is wide, loss is big.
The fire-retardant research of bituminous, be on the fire-retardant research basis of chemical materials, to grow up, China's combustionproperty standard of just having formulated all kinds of chemical materialss is early measured (GB10707-1989), insulating liquid combustibility test method (GB T 16581-1996), plastics combustibility test (GB 2406-1980) etc. as textile combustion performance test (GB T 5454-1997), glass filament reinforced plastics combustibility test (GB 8924-1988), rubber combustionproperty.
Fire retardant commonly used at present can be divided into organic class, mineral-type and complex class.Organic fire-retardant commonly used has tricresyl phosphate (β-chloroethyl) ester (TCEP), tricresyl phosphate (2-chloropropyl) ester (TCPP), tricresyl phosphate (2,3-two chloropropyls) ester (TDCPP) etc.; Inorganic combustion inhibitor commonly used comprises aluminium hydroxide, zinc borate, antimonous oxide etc.; Composite flame-retardant agent is to have multiple fire retardant to be composited, and can bring into play the advantage of each fire retardant, thereby plays good effect.Existed test results shows, the adding of fire retardant is less to the influence of the pavement performance of asphalt, but can effectively improve the bituminous oxygen index, thereby plays fire retardation.
When pitch is carried out fire-retardant finish, select to be suitable for the bituminous fire retardant, selection of fire retardant depends on bituminous character, environment for use, working method, economic condition etc., and wherein, fire retardant is most important to the bituminous fire retardancy.When selecting fire retardant, whether the temperature range of relatively more crucial is fire retardant performance flame retardant effect is complementary with the bituminous heat decomposition temperature.If fire retardant and pitch thermostability differ greatly, just be unfavorable for asphalt flame-retardant.The thermal degradation temperature scope of fire retardant and bituminous thermal degradation temperature scope should be tried one's best approaching.If the thermostability of fire retardant is more much better than pitch, when the needs fire retardant played a role, it may still not react, thereby does not produce flame retardant effect so; If the thermostability of fire retardant is than low many of bituminous, fire retardant will lose flame retardant effect in advance when pitch does not also have thermolysis.So the fire retardant of selection will be complementary with the bituminous heat decomposition temperature just can reach flame retardant effect preferably.As seen, tunnel sheet pavement admixture fire retardant should satisfy: 1. flame retarding efficiency height, under the as far as possible little prerequisite of consumption, can give the good flame retardancy of base material, self-extinguishing; 2. good with bituminous dispersiveness, intermiscibility; 3. good stability does not decompose during processing, and can be retained in the pitch performance flame-retarded efficiency during fire for a long time; 4. cheap, and do not have remarkable undesirable action.
Take all factors into consideration the flame retardant effect of various fire retardants, according to the existing achievement in research of flame-retardant pitch and tunnel sheet pavement in the fire field thermal behavior and degradation production to the harm of life, property, and smog is discharged characteristics such as smooth, evacuating personnel difficulty when the semiclosed tubular structure of integrating tunnel, fire, this patent is selected the environment-friendly type organic fire-retardant, and is applied in the bituminous pavement of some concrete Tunnel Engineering.But along with the damage of tunnel sheet pavement layer, fire retardant has also lost fire retardation, how to keep the flame retardant effect of bituminous pavement to need further to inquire in the tunnel sheet pavement maintenance stage.
4. tunnel sheet pavement maintenance process
The maintenance process of tunnel sheet pavement has multiple, and wherein little table place is one of main method of tunnel sheet pavement maintenance.Little table place be a kind of by polymer modification emulsified bitumen, continuous grading gather materials, filler, water and additive, pave after evenly mixing and stirring by rational proportion former road surface one or more layers, can reach the laminate structure of rapid open to traffic requirement.It is a kind of new road maintenance process that grows up on the slurry seal basis.Therefore have characteristics such as the scope of application is wider, performance is better, the most effective to the reparation that appears at the various diseases on arterial street, tunnel concrete road surface, motorway and the airport roadway, be one of the most perfect Road maintenance method of function.
Little table place is the highest form of emulsified bitumen slurry cover, and it is applicable to the preventive maintenance of important traffic route such as motorway, urban trunk, airfield runway etc.Little table place is made up of polymer modification emulsified bitumen, 100% grating building stones, mineral filler, water and necessary additive, uses special construction facility to pave while mixing and stirring.The anti-slide performance that the road surface can be improved by little table place stops and to ooze, to prevent the aging and loose of road surface under the moisture, thereby prolongs the work-ing life on road surface effectively.The use at little table place can be implemented individual layer or bilayer paves according to pavement behavior, and stable rut can also be filled up by little table place.Open to traffic in the short period of time after micro-surfacing mixture paves, the concrete time is different because of the practical situation of each engineering.Usually the seal that 12.7mm is thick can be in 1 hour more than 24 ℃, when humidity 50% is following open to traffic, bear wheel and roll, but brake, starting or turning can not be arranged.There is high requirement at little table place to its composition material, and it requires the building stones must be firm, wear-resisting and clean, grain formula or coarse grain formula during the grating of building stones adopts usually, and the thickness after the moulding is generally about 5mm or 10mm.The emulsified bitumen that little table place is used must normally adopt SBR latex through polymer modification, also can adopt the SBS modification, and its residue has higher softening temperature.Early in the world its requirement is not quite similar, but generally is to adopt the requirement of ISSA to be not less than 57 ℃.Above-mentioned requirements is in order to guarantee adhesivity high between pitch and the building stones and the splendid wear resistance of little table place cover, thereby guarantees that little table place cover still can reach long work-ing life under the heavy traffic effect.External investigation shows and was generally the work-ing life at little table place 5 to 6 years that long reaches 8 years.Design of Mixture for Thin Surfacing has increased by 6 days wear test and has rolled the scab test on the basis of slurry seal, to assess its anti-bad ability of damage by water and maximum asphalt content, also need to roll deformation test when being used to fill up rut.In addition, the bitumen aggregate ratio cocoa of micro-surfacing mixture adopts marshall's method or Wei Mufa to determine.Also can be directly used in the surface abrasion layer of newly-built road as little table place of preventive maintenance technology, thereby reduce the use of expensive building stones, reduce construction costs, significantly reduce the generation that the basically eliminate early water damages.
Therefore, how to the timely maintenance of tunnel sheet pavement, improve the using character of tunnel sheet pavement, still keep the flame retardant properties of bituminous pavement after maintenance, reducing tunnel fire hazard safety also needs further investigation.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of environment-friendly type tunnel flame-retardant micro-surfacing asphalt, this fire-retardant compound can continue to make tunnel sheet pavement have flame retardant effect after little table place maintenance punishment in the tunnel sheet pavement operational phase, and have environmental-protection function, do not influence original micro-surfacing construction technique.
Technical scheme: at when the tunnel sheet pavement presence of fire is burnt, the tunnel road surface medium pitch plays combustion-supporting characteristics.In order to make the tunnel sheet pavement operational phase after the place's maintenance of little table, can continue to make tunnel sheet pavement have flame retardant effect, has the effect of environmental protection simultaneously.The organic fire-retardant of employing environment-friendly type when construct at the little table of tunnel sheet pavement place on the one hand carries out flame-retardant modified and does not change every performance of former compound modified emulsifying asphalt; On the other hand, constant at the tunnel sheet pavement micro-surfacing construction technique, need not preparation of construction is improved.Technique scheme does not change the result of use of original bituminous pavement after little table place maintenance punishment.Each component ratio of environmental-protection flame-retardant micro-surfacing mixture of the present invention is according to table 1 admixture.
