A stone-exposed road surface paved by a novel stone-exposed road surface construction method is a solvent-containing multi-component epoxy base system, wherein various components are stirred according to a certain ratio and sequence, and then are paved, then a stone-exposed road surface aggregate is uniformly paved, and the excess aggregate is removed after curing to form the stone-exposed road surface.
Description
One. affiliated technical field is originally
The invention belongs to the highway construction category, be the highway engineering construction technical field of construction.
Two. background technology
Cement pavement is because its intensity height, good stability, no rut, good endurance, cost are moderate, the visual plurality of advantages such as good of driving at night. be subjected to the attention of various countries road department.
Yet cement pavement also has some to be badly in need of improved problem.
The skid resistance of cement pavement is that people are concerned about the problem more with research always.Along with development of economic construction, road quality classification improves constantly, and the traffic volume increases, the speed of a motor vehicle is accelerated, and the antiskid problem of cement pavement becomes increasingly conspicuous, especially in rainy season, moist pavement skid resistance condition reduces greatly, easily makes vehicle slip out of control, causes casualties, major accident such as property loss.To this, work out some antiskid technology both at home and abroad, as plucking, embossing, cutting, promptly so-called " first generation, the second generation, third generation antiskid technology ".Show that through long-term the use road surface plucking easily is polished, the skid resistance decay is very fast, and road surface embossing, cutting increase less to skid resistance, and the handstone in the embedded groove easily makes the road surface fragmentation.So these technology are failed root wood and are solved the antiskid problem of cement pavement.
Enhancing along with people's environmental consciousness, the traffic noise that cement pavement produces is paid close attention to more, " noise road surface " become the another synonym of cement pavement, and under the situation that requires to improve constantly at the road pavement using character, this defective can become the restraining factors of cement pavement development; Reduce highway traffic noise, particularly reduce dense population areas, close on the quick industrial siding in city, the traffic noise in the tunnel, oneself is the have to problem considering and solve of engineering department.
The glare problem of cement pavement does not cause the attention of research and construction department always, but it is the key factor that influences person for driving a car's vision, and eliminating this adverse effect is the importance that improves cement pavement driving comfort, safety.
For adapting to the Modern Traffic growth requirement, study the endurable road surface of high antiskid, low noise and surface work theory and be very important with technology.
The endurable road surface of high antiskid, low noise and surface work should possess two kinds of structures: a kind of be microtexture (horizontal direction 0～0.5mm, vertical direction 0～0.2mm), it is the main because of rope of road surface anti-slide performance when influencing low vehicle speeds (speed of a motor vehicle is at 50km/h); (horizontal direction 0.5～50mm, vertical direction are 0.2～10mm), and it is the principal element of road surface anti-slide performance when influencing high speed traveling (speed of a motor vehicle is greater than 50km/h) in the macrostructure that open space, hole and groove between another kind is gathered materials by the road surface formed.The cement mortar that the good sand of quality, suitable sand coarse aggregate ratio and cement are formed makes the Portland cement concrete pavement surface have good microtexture, can satisfy the antiskid requirement under the low vehicle speeds, in general, adopt bulky grain sand can make the road surface keep certain microtexture, so cement pavement improves and keep the key of anti-slide performance to be to form good macrostructure.
The low noise realization of cement pavement is mainly inhaled noise by the instantaneous pump that reduces vehicle tyre and road surface, reduce the vibration noise between tire and road surface and obtain, this two aspect reduce to exist contradiction, coordinate this contradiction and can obtain the lower cement pavement of noise, promptly become the low noise cement pavement.And reduce pump suction noise, impact noise and coordination approach thereof also is to realize by forming the road surface macrostructure. correspondingly, the road surface is also eliminated the noise of blowing a whistle of horizontal cutting the normal reflection and the tire of noise.
Making porous crack cement pavement can form the low noise cement pavement, because, more hole can reduce pump on the one hand and inhale noise, on the other hand the noise that produces is had the certain absorption effect, make the effect noise on tire and road surface reduce like this, thereby reduce traffic noise.Abundant hole can make this kind road surface have certain internal drainage function, under any weather conditions, all has good skid resistance. and mushy cement pavement also is a kind of selection of antiskid low noise cement pavement.But, because hole is many, can make the road surface comprehensive mechanical property be difficult to meet the demands, directly can produce the problem that is difficult to overcome as surface layer.Therefore, need seek more rational antiskid, low noise cement pavement.Reveal a kind of so just road surface of stone cement concrete pavement (Exposed-Aggregate Cement Concrete Pavemont is called for short EACCP).
Reveal the stone cement concrete pavement, be after the moulding of surface layer cement concrete mixture making, spray and reveal stone agent and the health of plastic covering film, by revealing stone agent effect coagulating cement scholar surface course is carried out chemical treatment during this time, delay condensing of surperficial certain thickness cement mortar, but do not influence the concrete normal setting and harden of main body, after the main body concrete reaches certain intensity, scrub its surface and carry out the surface except that slurry, expose equally distributed coarse aggregate, formed like this cement pavement reveals stone cement concrete pavement (EACCP) exactly.
EACCP is except that keeping characteristics such as ordinary Portland cement pavement strength height, long service life, maintenance costs are low, because its good macrostructure and microtexture, have some excellent functional performancies. at first, pavement skid resistance condition is greatly improved, special anti-slide performance in the rainy day significantly increases, and the pavement skid resistance ability retention time is long, is difficult for being worn; Secondly, expose owing to gathering materials and to have reduced pump suction noise, the traffic noise level is significantly reduced; EACCP forms diffuse reflection to strong light in addition, can eliminate or slow down the interference of dazzling light to driver, pedestrian, gets rid of the reflective phenomenon of dazzling the eyes, and improves the security performance on road surface. and therefore, reveal the stone road surface and have good functional performance and wide application prospect.
In China, reveal the stone road surface research, use under test always and can't large tracts of land promote, tracing it to its cause mainly contains following two aspects:
1. reveal the use of stone agent and the big making cost that has increased the road surface of cost that slurry is removed on the surface
1. reveal stone agent unit price: 50 yuan/kg, use amount 0.5kg/m
2, reveal stone agent cost and make dew stone road surface increase by 25 yuan than the every square meter of cement concrete pavement;
2. reveal the binder that will rinse out 4mm～10mm in the forming process of stone road surface, the cement concrete unit price: 1200 yuan/cube, reveal 4.8 yuan～12 yuan of the every square meter waste in stone road surface binders;
3. revealing stone pavement curring film cost makes dew stone road surface increase by 5 yuan than the every square meter of cement concrete pavement;
4. the waterwheel cost makes and reveals the stone road surface than 5 yuan of the every square meter increases of cement concrete pavement;
5. labour cost (reveal stone agent sprinkling, membrane curing, dispose top layer cement mortar binding material) makes and reveals the stone road surface than 40 yuan/square meter of the every square meter increase of cement concrete pavement;
Reveal the every square meter in stone road surface and increase by 79.8 yuan～87 yuan than the Portland cement concrete pavement cost;
With common high speed top course is example, thickness 28cm, and maximum rubble 40mm, C20 concrete, 425 cement materials, cost is 70 yuan/every square.Reveal the stone pavement construction, make the top course cost increase by 114%～124%, general owner unit all is difficult to accept.
2. pavement construction complex process on the existing dew stone coagulating cement is revealed the sprinkling moment, the length of overlay film conditioned time, the surface of stone agent and is removed the degree of starching, and the uniformity of revealing the stone height all can have influence on the effect on dew stone road surface.Before the relevant speciality construction machinery is not developed, rely on artificial construction's difficult quality guarantee.

3. the check on the present invention " a kind of novel dew stone pavement construction method " construction road surface
(1). the check of cling property
Road surface cling property under moist unfavorable conditions reduces greatly, causes traffic accident easily, reveals the stone surface and has the surface of good drainage performance, and effective contact area on energy oversize tyre and road surface provides enough coefficients of sliding resistance, reduces accident rate.
Macrostructure as the road surface factor can be estimated by average construction depth (MTD) index of current specifications method: adopt the sand volumetric method to measure usually, be about to oneself and know that the standard sand stand of capacity fills out in clean and dry road surfaces texture, measure the area of its covering, by
This calculates average construction depth (MTD).General MTD is big more, and surface macro texture is abundant more, and the road surface anti-slide performance is high more during high vehicle speeds;
Revealing vertical cling property on stone road surface estimates with antiskid index SN: the trailer of code test tire is housed, travels at the moist road surface of watering with standard speed (being generally 60km/h). measure that the testing wheel quilt locks (100% slip rate) fully or required tractive force F during with a certain fixedly slip rate (as 86%) slippage
T, the useful load P divided by on the wheel just can obtain friction factor, is called braking force coefficient BFC, also can be described as antiskid index SN
Revealing the horizontal cling property on stone road surface estimates with sideway force coefficient SFC: testing wheel on the trailer and travel direction deflection certain angle, suffered lateral force Fs when measuring this wheel slip, useful load P divided by on the wheel just can obtain wasting the resistance coefficient. be referred to as sideway force coefficient SFC
The method of estimating current pavement skid resistance condition in the existing rules has manual sand patch method, electronic sand patch method, laser texture meter method, portable pendulum tester method, braking distance method and friction coefficient testing car method (longitudinal force coefficient method, cornering ratio method).
(2). the detection of noise reduction performance
According to China The Law on Environmental Protection of the People's Republic of China; on August 19 " standard for acoustic environmental quality " in 2008 (GB 3096-2008), Xiang Guan noise testing standard comprises therewith: " acoustics, environmental noise measurement method " GB/T 3222-1994, two measurement standards of " city regional environment noise measuring method " GB/T 14623-1993. are applicable to the measurement of city area environment, main line of communication noise.
Objective measurement to noise generally adopts sound pressure level, sound intensity level or sound power level, but by equal loudness contour as can be known, people's subjective sensation also is subjected to frequency influence.In order to make measuring of sound consistent, at measuring apparatus, as all having installed the weighting network to frequency, i.e. wave filter on the sound level meter with the human auditory system impression.It establishes certain decay to the sound that is received by frequency band. and come the auditory properties of anthropomorphic dummy's ear, the sound level that obtains like this is called the weighted sound level.Weighting network can be divided into A, B, C and Lin weighting network, and the sound level meter that has also has the D weighting network.Measured sound pressure level is called A, B, C, D sound level, and C and Lin are called overall sound pressure level again.Because tested sound is during by the A network, low-frequency range has bigger decay, relatively meets people's ear to the sensitivity of the all-bottom sound sense of hearing characteristics than high frequency sound difference, thus now general in the world be the A sound level, note is made dB (A),
(3). pavement reflecting service check method
High brightness object in the visual field or strong luminance contrast thing make the observer produce worry, and produce phenomenon uncomfortable or visual function and sighting distance reduction, are called dazzle.
We know that cement pavement is commonly referred to " white pavement ", when light shines thereon, strong reflex can take place.The driver is driving for a long time on cement pavement, and it is uncomfortable that eyes can be felt, when especially summer, sunlight was strong.In this case, for the fatigue of easing eyes, the rider can turn to other places to sight line usually, but the driver can not.Because the driver will reach safe, quick, comfortable purpose when driving, just must observe the road conditions in the place ahead all the time, when driver's asthenopia can't be alleviated, just might cause the generation of traffic accident.
For bring unfavorable and dangerous glare phenomenon to the driver, people are existing to be familiar with, but does not take concrete measure to solve.Therefore study the harm that suitable measure alleviates and eliminate this phenomenon, to improve the security performance on road surface, it is very necessary reducing traffic accident.
For the road surface, the reflective function of road table structure road pavement has considerable influence.Asphalt concrete pavement is better than cement concrete pavement as dark-coloured pavement aspect reflective, anti-dazzle, and reveals the particularly colored stone road surface of revealing, stone road surface, because the structure of itself uniqueness, reflective function is greatly improved than traditional cement pavement.
Gathering materials that expose on particularly colored dew stone road surface, dew stone road surface itself has certain color, and it can absorb some light, alleviates the intensity of road reflection, and gather materials formation good little, the macrostructure of exposing, and can form diffuse reflection to strong light.
This optical characteristics can prevent that sunlight is dazzling, the environment of safety and comfort is provided for driver and pedestrian.
The method of inspection:
1) will measure plate with middle black cloth with holes or black paper and cover, open light source, light will be projected the measurement plate at hole place, and write down θ, Ψ, r, R.
2) under identical measurement environment, measure the scattering coefficient K of reference plate magnesium plate.。
3) value of change θ, Ψ, R is carried out comparing and measuring under the different modes.

When construction depth is that 1mm is, the corresponding dew stone degree of depth is 1.83mm, is 1/3 of aggregate size and reveal the stone degree of depth, so the best aggregate size of recommendation is 5.5mm.
By drawing to draw a conclusion to last table data analysis:
1.. greasy dirt dyes under the situation, and this technology is revealed the antiskid pendulum value on stone road surface greater than other road surface types antiskid pendulum values;
Can see from Figure 18 and Figure 14, under the same oil degree of contamination, the skid resistance on this technology dew stone road surface is better than the road surface of other types, having under the regimen condition, this technology is revealed stone pavement skid resistance value on average about 55BPN, and flexible pavement is 50BPN, and the cutting rigid pavement is 40BPN, and light surface concrete road surface only is 32BPN; Dye under the situation at slight greasy dirt, the antiskid value that this technology is revealed the stone road surface can remain between 28～22BPN, flexible pavement is 21BPN, cutting and light surface concrete road surface can only remain between 10～16BPN, when this species diversity is dyed seriously at greasy dirt, still exist: construction depth is that to reveal stone road surface and construction depth be 0.76 asphalt concrete pavement to this technology of 0.75mm, both construction depths are roughly the same, but the greasy dirt in same degree dyes down, and this technology is revealed the antiskid value on stone road surface greater than asphalt concrete pavement.
2. reveal stone effect of depth greasy dirt and dye the antiskid rate of decay under the situation
Reveal the big dew stone road surface of the stone degree of depth and dye down at greasy dirt, it is slower that the pavement skid resistance value increases early stage decay with degree of contamination, and it is little to reveal the stone degree of depth, and early stage decay is very fast, but the antiskid value of revealing the stone road surface at last all will tend towards stability, as shown in figure 15.
For Figure 15 construction depth is the dew stone road surface of 1.0mm, with oil mass during less than 10g, this less with low on fuel to fill up the space between gathering materials, so the decay of friction factor is slow, and when reaching 10g with oil mass, machine oil has filled up the space between gathering materials fully, and forms continuous pasta on the surface of exposed concrete, the pavement skid resistance value drops to 13BPN from 20BPN, declines by a big margin.And construction depth is the dew stone road surface of 0.34mm, and during with oil mass 6g, the surface has just formed approximately continuous oil film, the pavement skid resistance value decays to 14BPN from 21BPN, and attenuation ratio is very fast, increases with oil mass again, the surface is still one deck oil film, and the pavement skid resistance value has small decay and tends towards stability basically.
Friction factor under the regimen condition is arranged along with situation such as Figure 16 of revealing the stone change in depth.As can be seen from the figure, after obtaining certain construction depth (0.7mm), the increase that The friction coefficient is revealed the stone degree of depth changes less.After construction depth was greater than 1.0mm, The friction coefficient was revealed the increase of the stone degree of depth and is diminished.
