Description
The color asphalt concrete that the present invention's energy is luminous, production technique is simple and direct, and the scope of application is extensive, compliance with environmental protection requirements.
One, affiliated technical field
Belong to the public works category, be municipal engineering construction material technology field.
Two, background technology
1, to inventing the understanding of " color asphalt concrete that can be luminous ".
The color asphalt concrete that the present invention's energy is luminous, it at first is the colourless agglutinate of preparation.Colourless agglutinate is that to adopt petroleum resin (Ss) and mineral oil (Ks) be base-material, a kind of as properties-correcting agent in adding ethylene-vinyl acetate copolymer (EVA) or the styrene-butadiene-styrene block copolymer (SBS).It mixes post-heating to certain temperature according to a certain percentage and is molten state, makes solid petroleum resin (Ss) abundant swelling in mineral oil (Ks), again through the high speed shear effect, each component is mixed mutually, forms uniform mixture, makes colourless agglutinate.SS is solid-state shape at normal temperatures, agglutinating value(of coal) height, lighter color, Heat stability is good, but character is crisp hard, and impact resistance is relatively poor, can not be separately as the road agglutinate.KS is as petroleum by-product, is the thickness shape that flows at normal temperatures, with SS good compatibility arranged, and plasticising simultaneously, increasing tougheness are good.At a certain temperature, dissolve SS swelling in KS of shape, form mixture, solid-state SS fragility is reduced, plasticity, toughness strengthen, and mixed agglutinate can satisfy Ordinary Rd to be used, but its visco-elasticity zone is little, can not take into account the high temperature performance requirement simultaneously.Therefore, in mixture, add a kind of among EVA or the SBS as properties-correcting agent, after the high speed shear effect, be scattered in the colourless agglutinate system, can substantially improve the high-temperature stability and the low-temperature cracking-resistance of colourless agglutinate, be prepared into the colourless agglutinate that meets the road use properties.
Materials such as colourless agglutinate or decolouring pitch or color asphalt and versicolor building stones, stopping composition, tinting material, luminescent material (as the ball-type hollow glass micropearl etc.) and auxiliary agent mix stirring under specific temperature and time, be prepared into the luminous color asphalt concrete of various energy.In color asphalt concrete proportioning design that can be luminous, do not add any luminescent material, both can be prepared into various color asphalt concretes.Color asphalt concrete and color asphalt concrete that can be luminous, through paving, rolling and making becomes pressure and the thrust have persistent adhesivity and can bear the vehicle high loading, meet the luminous color asphalt concrete road surface and the chromatic bituminous concrete pavement of energy of road use properties again.It has the ductility height, intensity is good, anti-low-temperature cracking, high temperature do not soften, do not fade, and resistance of aging is strong in the sun, certain elasticity and plastic deformation ability are arranged, the vibration damping of height is arranged, with automobile tyre sticking power is preferably arranged, coefficient of friction is big, braking ability is good, not airborne dust and clean easily and wash, maintain conveniently.
The three-phase system that color asphalt concrete that the present invention's energy is luminous and color asphalt concrete are made up of colored mineral aggregate, tinting material, luminescent material, colourless agglutinate rubber cement or decolour pitch or color asphalt and air, wherein colored mineral aggregate is made up of coarse aggregate, fine aggregate, it is discontinuous disperse phase, and colourless agglutinate rubber cement or decolouring pitch or color asphalt are dispersion medium, also have breeze in addition in the compound as filler, in compound, also play an important role.Nature difference between the moiety of its compound is big, and (colored coarse aggregate particle is a solid, institute's Chromatic color gathers materials, luminescent material is a prose style free from parallelism, colourless agglutinate or decolouring pitch or color asphalt then high temperature are fluid, low temperature is solid, normal temperature is glutinous elasticoplastic body), increased the complicacy of its compound.The present invention compares with hydraulic cementing materials with other homogeneous materials, and structure is more open, has tangible particle discrete material mechanical characteristics.The space structure of its compound is a jelling structure, is the cancellated dispersed system in a kind of multistage space.In this structure, the particle that gathers materials is bonded together by colourless agglutinate or decolouring pitch or color asphalt film, and its structural strength depends on the internal friction resistance and the cohesive force of compound to a great extent.The ratio shared in " embedding is extruded into branch " in its network structure and " closely knit composition " is different, the color asphalt concrete that can be luminous and the composition structural form of color asphalt concrete have three kinds of typical types: (1) suspension compact structure (ACI) is when adopting the colored mineral compound of successive type close-graded (I type grating), when color asphalt concrete that the energy that luminescent material and colourless agglutinate or decolouring pitch or color asphalt are formed is luminous and color asphalt concrete, press the particle interference theory, gather materials to the interference of prime solid matter for avoiding secondary, must reserve the space bigger slightly between prime is gathered materials and supply to arrange secondary gathering materials than secondary aggregate size.Compound by this composition, though can obtain very big degree of compactness through Mi Duo repeatedly, but at different levels gather materials be secondary gather materials the institute separate, can not directly draw close and form skeleton, just as be suspended in secondary gather materials and colourless agglutinate rubber cement or decolouring pitch or color asphalt between, color asphalt concrete that the energy of this structure is luminous and color asphalt concrete have higher cohesion (c), but frictional resistance angle (﹠amp; ) lower, its intensity is controlled by cohesive force mainly, so high-temperature stability is relatively poor, and under the heavy-duty car action of traffic loading, the road surface may produce distortion such as rut, wave, passing.(2) skeleton gap structure (AM, AK) is when adopting luminous color asphalt concrete of the colored mineral compound of successive type open gradation (II type grating), luminescent material and the energy of colourless agglutinate or decolouring pitch or color asphalt composition and color asphalt concrete, because this mineral compound decline factor is big (being that the n value is bigger in the n power formula), the shared ratio of coarse aggregate is higher, fine aggregate then seldom even does not have.By the compound of this composition, coarse aggregate can be drawn close the formation skeleton mutually; But because fines quantity is very few, be not enough to fill up the space between the coarse aggregate, therefore form " skeleton-space " structure.Three experiments of the compound of this structure show, though have higher internal friction angle (﹠amp; ), but cohesion (C) is lower, and its intensity depends primarily on inner frictional resistance, and cohesive force is accessory relatively.Because coarse fodder forms skeleton, thereby thermostability is good, but voidage is too big pavement durability is affected in this structure.(3) closely knit skeleton structure (SMA) is when adopting luminous color asphalt concrete of the colored mineral compound of discontinuous form close-graded, luminescent material and the energy of colourless agglutinate or decolouring pitch or color asphalt composition and color asphalt concrete, gone gathering materials of intermediate sizes particle diameter because this mineral compound is disconnected, both the coarse aggregate of a greater number can form spatial skeleton, but therefore the space that a considerable amount of fine aggregate packing skeletons are arranged again simultaneously forms " closely knit-skeleton " structure.Three experiments of the compound of this structure show that this kind structure not only has higher cohesion (C), and higher angle of internal friction (﹠amp is arranged; ).Theoretically, belong to the luminous color asphalt concrete and the color asphalt concrete of energy of this kind structure type, should have optimum mechanical property.Such compound has good anti-water damage and endurance quality because of the mutual interlocking that gathers materials together.
In addition, suitably improve the denseness of colourless agglutinate or decolouring pitch or color asphalt, control the ratio of colourless agglutinate or decolouring pitch or color asphalt and colored mineral aggregate, luminescent material, control colourless agglutinate or decolouring pitch or color asphalt consumption, use alkalescence is gathered materials, adopt active higher breeze, improving the interaction between colourless agglutinate or decolouring pitch or color asphalt and colored mineral aggregate, the luminescent material, thereby improve the cohesion of its compound.Adding anti-stripping agent in colourless agglutinate or decolouring pitch or color asphalt is the effective measure that strengthen anti-water damage.Dope superpolymer such as SBR in colourless agglutinate or decolouring pitch or the color asphalt, to improve can be luminous the color asphalt road surface and the crack resistance at low-temperature on color asphalt road surface have comparatively obvious effects.
2, the present invention has that characteristics are remarkable, color is various and is widely applicable
Color asphalt concrete and color asphalt concrete that can be luminous, it has good street road use properties.It meets the luminous color asphalt concrete road surface and the chromatic bituminous concrete pavement of energy of road use properties through paving, rolling and making becomes pressure and the thrust have persistent adhesivity and can bear the vehicle high loading.It is under different temperature and outside atmosphere effect, and high-temperature stability, anti-water damageability and weather resistance are all very good, and distortion does not appear, the color asphalt film such as peels off at phenomenon, and is good with basic unit cohesiveness; It has bright in colour lastingly, do not fade, the high temperature of 77 ℃ of abilities and-26 ℃ low temperature, not airborne dust and clean easily and wash, maintain conveniently; It has stronger sound absorption function, and doughnut during high speed scroll, can also not absorb other noises that come from the outside simultaneously because of the air compression produces powerful noise on road; It has good elasticity and flexibility, and " feel " is good, has antiskid function, is fit to pedestrian's stroll.The present invention can have multiple colors such as redness, yellow, blueness, green, white, the colour of camel's hair by luminous color asphalt concrete and color asphalt concrete, its color is mainly from building stones self color and a little tinting material, it is not only attractive in appearance, and the light ends performance is few, compliance with environmental protection requirements, widely applicable.

2Determine best colourless agglutinate or decolouring pitch or color asphalt consumption initial value OAC; 5. the marshal piece by the colourless agglutinate of the best or decolouring pitch or color asphalt consumption OAC making is carried out stable check of water and rutting resistance check, see whether meet the requirements, as undesirable, reply mineral aggregate gradation or colourless agglutinate or decolouring pitch or color asphalt consumption are adjusted, and carry out the proportioning design again; 6. through adjusting repeatedly and the Comprehensive Experiment result, and, comprehensively determine mineral aggregate, luminescent material grating and colourless agglutinate or decolouring pitch or color asphalt optimum amount with reference to working experience.
Secondly, carry out the production mix proportion design, its method and step are: because China's building stones specification division is thicker, continuous mixer can't be produced qualified bituminous concrete, the therefore essential batch mixer that uses.Batch mixer is broadly divided into the cold burden distribution system, the heating system of gathering materials, hot screen sub-system, metering control system, mix and stir system.Wherein, the hot screen sub-system is that the mineral aggregate with super particle diameter sifts out, thereby if provide best oilstone when when mineral aggregate, luminescent material ratio with the last stage, not obvious if the different size mineral aggregate is stacked, or the regrading aperture is provided with discomfort or breakage, all will change it and mix house material performance.To batch mixer, the material sampling that must enter each hot aggregate bin behind the regrading is sieved, to determine the material proportion of each hot aggregate bin, use when controlling for amalgamator.The material proportion of adjusting simultaneously the cold burden storehouse repeatedly to be reaching the feed equilibrium, and gets best colourless agglutinate or the decolouring pitch or the color asphalt consumption of Target Mixture Ratio design.Best colourless agglutinate or three colourless agglutinates such as decolouring pitch or color asphalt consumption ± 0.3% or decolouring pitch or color asphalt consumption carry out the Marshall experiment, determine best colourless agglutinate or the decolouring pitch or the color asphalt consumption of production mix proportion.This stage focus is in time to check heat mixture screening grating and extracting experiment bitumen aggregate ratio to determine the amalgamator serviceability, and by mixing and stirring the Marshall experimental result adjustment mineral aggregate ratio of material, step is as follows.
(1) determines each cold burden storehouse sub-material speed: according to the ratio of gathering materials that Target Mixture Ratio is determined, set each cold burden storehouse rotating speed of motor, and guarantee that by adjusting rotating speed of motor the various supplies of gathering materials are balanced, not produce indivedual hot storehouse flashes or to treat that material is for suitable.
(2) determine the aperture of each hot storehouse sieve aperture: the configuration of hot aggregate vibrating screen screen size should be according to the type selecting of compound.The first, should guarantee that the particle that exceeds maximum particle diameter all rejects, when maximum particle diameter has particular requirement, should adjust sieve aperture as requested; The second, should make full use of the hot storehouse resource of amalgamator, and heat be expected reasonable classification according to the classification situation of cold burden, make the unlikely difference of the material quantity that enters each hot storehouse too big, prevent to wait to expect and flash, reduce output.
(3) adjust the hot storehouse proportioning of gathering materials: the material in each hot storehouse is taken a sample respectively, sieved, adjust hot storehouse proportioning to adhering to specification.With hot storehouse proportioning input amalgamator control computer, go out to mix and gather materials, whether the check mixed grating of gathering materials meets design requirement, be adjusted to meet the requirements till.
(4) determine compound construction proportioning: according to the adjusted hot storehouse proportioning of gathering materials, mix and stir 3 dish color asphalt concretes respectively according to the best colourless agglutinate of Target Mixture Ratio or decolouring pitch or color asphalt consumption, best colourless agglutinate or decolouring pitch or color asphalt consumption ± 0.3%, the mineral aggregate gradation check behind Marshall experiment, bitumen aggregate ratio experiment and the washing oil is carried out in sampling.Get the creme de la creme and be decided to be production mix proportion.
(5) carry out the checking of production mix proportion: production mix proportion highway section by experiment carries out the productivity checking, can put into production use after qualified.Amalgamator adopts production mix proportion to carry out trial mix, making experimental road, and carries out the Marshall examination with the core that drills through on the luminous color asphalt concrete of the energy that mixes and stirs and color asphalt concrete and the road, thus the standard mix of definite production usefulness.Standard mix is as the foundation of producing upward control and the standard of quality test.Must not arbitrarily change in construction process through designing definite standard mix.In the production process, as run into that the material of marching into the arena changes and after testing its compound mineral aggregate gradation, when the Marshall technical indicator is undesirable, should in time adjust proportioning, its quality is met the requirements and keep relative stability, carry out the proportioning design in case of necessity again.
Once more, be to stirring by luminous color asphalt concrete and color asphalt concrete.Before stirring, mix and stir cylinder and asphalt delivery pipeline, transport trolley, construction equipment etc. of stirring station be cleaned up; The productive target proportioning will be stablized, be made to material property, can be to greatest extent near design mixture proportion; When earlier mineral oil (Ks) being heated to 150 ℃～170 ℃, adding petroleum resin (Ss) and stir; Then, add a kind of stirring the among EVA or the SBS again.Since tinting material and auxiliary agent than great, in compound, have painted, disperse, absorption, stable, viscosifying action, need consider its influence during interpolation to environment, should be before producing according to Target Mixture Ratio, calculate the consumption of every dish compound tinting material and auxiliary agent, and install with polyethylene plastic bag, in whipping process by artificial auxiliary the adding; The color asphalt concrete that can be luminous and the stirring of color asphalt concrete adopt batch mixer to mix stirring under 130 ℃～160 ℃ temperature, and every dish mixing time is preferably 40s～70s, with compound uniform mixing degree of being.Should check in time after the discharging whether pellet and color be even.
