Description
Technical field
The present invention relates to a kind of elastomeric material that is used for laying road and preparation method thereof and with the method for its laying road, relate more specifically to the elastomeric material that is used for laying road that makes by following method: 1 weight % is selected from the polyurethane fragment, the EPDM fragment, at least a the mixing mutually at least a fragment (particle size of each is 10mm or littler) in the damaged tire fragment of powdered and the rubbery chip and the following material of being selected from of 0.01～0.10 weight %: SBR latex with the preparation mixture, SR latex, NR latex, epoxy resin, acrylic resin, polyurethane resin, pitch and EVA, the limestone powder that adds 0.01～0.15 weight % then, cement, silica sand, calcium carbonate or hydrated lime are with the surface of application of mixture, make the elasticity fragment of coating like this, then with the elasticity fragment of this coating of 1 weight % and the SBR latex of 0.005～3 weight % as flowable, SR latex, NR latex, epoxy resin, polyurethane resin, acrylic resin, EVA or pitch mix mutually, and described flowable is in the emulsion state because of having added water and emulsifier.And relate to a kind of method for preparing this elastomeric material with and the method used.
The elastomeric material that is used for laying road of the present invention is sprayed on the upper surface of bituminous concrete or cement concrete, thereby reduce the noise of vehicle ' on the road, in case of necessity, also can be used to renovate the asphalt pavement of damage or the cracking or the broken parts of repairing road.
Background technology
Usually the noise reduction in low noise paving be based on have 20% or the porous paving of bigger porosity realize that this paving is pitch type drainage asphalt concrete or cement mo(u)ld percolating water cement concrete.Effect about this porous paving noise reduction, the hole that forms in road has played the contraction that prevents the air between tire and the road surface or the effect of expansion, thereby suppress the generation of air suction noise, in addition, when the noise that produces by the motor of motor vehicles from the road surface reflex time, the hole role is to absorb such noise.
Yet, for traditional porous low noise paving, comprise drainage pavement or permeability paving, when hole was stopped up by impurity as time goes by, noise reduction weakened rapidly.Equally, for the porous asphalt concrete road, when water or impurity infiltrate by hole, can quicken the deterioration of pitch because of this contact, in addition, comprise the multiple useful oil of malthenes oil (being the key component of pitch), compare with plain asphalt concrete road with less hole, because porosity and deterioration more promptly makes the rapid hardening of pitch to cause noise reduction not good enough.
The favourable part in such porous paving (particularly drainage pavement) is, the noise reduction that it is experienced outside vehicle in travelling is better than the asphalt pavement (porosity 2～7%) of general dense-grade, but, disadvantage is that the noise reduction that the driver of the vehicle interior in travelling and passenger experience is not as good as the asphalt pavement (porosity 2～7%) of described general dense-grade.This is because in the occasion in porous paving, is sent to the driver there corresponding to the noise (250～500 hertz scope) of the rattle of tire friction sound generating before being absorbed by hole.So, under the situation in porous paving, need reduce the noise that driver in the vehicle under steam and passenger experience.For this reason, based on the noise reduction of the flexibility in paving itself than more favourable based on the noise absorption effect of hole.Yet in traditional porous low noise paving, these problems also are not resolved.
When very coarse or road cracking or part are damaged when the surface that makes road because of the road deterioration of laying, usually adopt such method repairing road: cut the road of deterioration or the surface of cracking or broken parts, above the zone of cutting thus, carry out process of deployment once more afterwards.Yet according to so common road rehabilitation method, at these restoring areas, the performance of conventional following paver is different from those new top pavers, thereby makes these materials be difficult to strong bonded each other.Therefore, the problem that exists bound fraction between the two to separate often.In addition, according to conventional method, when the road of renovation deterioration or repair cracking or during the road that damages, the engineering time significantly extends, and has correspondingly also improved construction cost.
Summary of the invention
Therefore, consider the problems referred to above that run in the prior art, the present invention has been proposed, one aspect of the present invention provides a kind of elastomeric material that is used for laying road, it is mainly by following use: at first, by being sprayed on bituminous concrete or the cement concrete, uses this elastomeric material, give the road flexibility, not only reduce the noise that vehicle produces in travels down thus, and reduced the noise that driver and passenger experienced in driving vehicle, the second, with low cost, the asphalt pavement of short engineering time renovation deterioration or the cracking or the broken parts of repairing road.
In addition, the present invention provides a kind of elastomeric material on the other hand, and it can be when the asphalt concrete surface layer, to use with the form of the mixture of traditional asphalt concrete material, thereby making the link table surface layer have flexibility, more comfort when producing vehicle ' and bigger noise reduce.
The preferred implementation explanation
According to the present invention, the elastomeric material that is used for laying road is to form like this: 1 weight % is selected from the polyurethane fragment, the EPDM fragment, in the waste tire fragment of powdered and the rubbery chip (hereinafter, be referred to as rubbery chip) at least a (particle size of each is 10mm or littler), mix mutually to obtain mixture with at least a in the following material of being selected from of 0.01～0.10 weight %: SBR latex, SR latex, NR latex, epoxy resin, acrylic resin, polyurethane resin, pitch and EVA, each all is liquid phase, the limestone powder that is selected from that adds 0.01～0.15 weight % then, cement, silica sand, at least a in calcium carbonate and the hydrated lime, and coating said mixture (hereinafter the general designation mixture that applies like this is " an elasticity fragment "), and then the elasticity fragment of 1 weight % mixed mutually with the material as flowable of 0.005～3 weight %, this material is for being selected from SBR latex, SR latex, NR latex, epoxy resin solution, polyurethane solutions, acrylic acid solution, at least a in EVA solution and the pitch, each all is in liquid emulsion state (having added water and emulsifier in this liquid emulsion).
Prepare the elastomeric material that the present invention is used for laying road by the following method:
The 1st operation: mixed rubber fragment and SBR latex and heating
This operation comprises at least a as the waste tire fragment that is selected from polyurethane fragment, EPDM fragment, powdered of rubbery chip and rubbery chip (particle size of each is 10mm or littler) with 1 weight %, at least a adding in the following material of being selected from of 0.01～0.10 weight %: SBR latex, SR latex, NR latex, epoxy resin, acrylic resin, polyurethane resin, pitch and EVA, each all is a liquid phase, then these materials are heated to 100～180 ℃, mix with blender simultaneously.Equally, preferably carry out heating steps, make direct contact mixture of heat, but the container outer surface of this mixture is housed, make that the temperature of internal tank is 100～180 ℃ with hot air with the indirect heating method.The reason that the heating-up temperature of rubbery chip is restricted to 100～180 ℃ is: the surface of rubbery chip is being lower than fully gelation under 100 ℃, and temperature when being higher than 180 ℃ rubbery chip may burn.
In this operation, as rubbery chip, useful especially is 100% by 10mm mesh sieve, and 10% or still less pass through the rubbery chip that the 0.074mm mesh sieves.When the size of rubbery chip during greater than 10mm, big like this rubbery chip has just become impurity in the paving, because process of deployment subsequently causes, reduce the rigidity in paving undesirably.On the contrary, when its size during less than 0.074mm, rubbery chip will burn at low temperatures, thereby reduces the quality of elastomeric material.In addition, the SBR latex, SR latex, NR latex, epoxy resin, acrylic resin, polyurethane resin, pitch or the EVA that are used for this operation are liquid phases, it all works in following operation: therefore the external surface that applies the rubbery chip of gelation also is attached in the gelation rubbery chip, the combination of SBR latex, SR latex, NR latex, epoxy resin solution, polyurethane solutions, acrylic acid solution, EVA solution or pitch that promotion adds as flowable in operation subsequently, and improve make up by the process of deployment paving in the hardness or life-span in paving of sclerosis.
Based on the rubbery chip of 1 weight %, use the SBR latex that is in liquid phase, SR latex, NR latex, epoxy resin, acrylic resin, polyurethane resin, pitch or the EVA resin of 0.01～0.05 weight %.When its quantity during, can not fully apply the surface of the rubbery chip of gelation less than 0.01 weight %.On the contrary, when its quantity during greater than 0.05 weight %, its result of use no longer increases, and the possibility height that is bonded to each other of the particle of rubbery chip, reduces quality undesirably.
The 2nd operation: use the limestone powder application of mixture
This operation comprises the mixture (hereinafter referred to as " rubbery chip mixture ") that the front operation with 1 weight % makes, be selected from least a adding in limestone powder, cement, silica sand, calcium carbonate and the hydrated lime with 0.01～0.15 weight %, when it is mixed, these materials are heated to 100～200 ℃, make limestone powder etc. be coated on the rubbery chip mixture, so prepare the elasticity fragment.
Add limestone powder etc. in the glue chips mixture so that its coated reason in surface is to prevent that the rubbery chip compound particles is bonded to one another, make these particles keep released state each other.In addition, when it was applied on the paving in later step, so the rubbery chip mixture that applies played the filler effect.In addition, when when preparing the elasticity fragment with coating rubber chips mixture external surfaces such as limestone powders, it can be stored very over a long time, also can easily be transported to and lay the place with packed storing state, and, because the particle of rubbery chip mixture exists with state separated from one another, can mix with the flowable of emulsion state effectively.
In this operation,, add at least a in limestone powder, cement, silica sand, calcium carbonate and the hydrated lime of being selected from of 0.01～0.15 weight % based on the rubbery chip mixture of 1 weight %.When its quantity during less than 0.01 weight %, rubbery chip mixture surface is not coated with limestone powder etc. fully, can cause the problem that the particle of rubbery chip mixture combines togather like this.On the other hand, its quantity is during greater than 0.15 weight %, because the excessive content of limestone powder etc. in process of production can produce a large amount of dust, and the gross weight of product increases greatly, to such an extent as to be not easy to its storage and transportation.
Under 100～200 ℃, with coating rubber chips mixture surfaces such as limestone powders.If application temperature is lower than 100 ℃, the surface of rubbery chip mixture is not coated with limestone powder etc. fully.On the other hand, if application temperature is higher than 200 ℃, rubbery chip may burn.
The 3rd operation: the elasticity fragment is mixed with SBR latex
This operation comprises that the elasticity fragment of the 1 weight % that will make in the aforementioned operation mixes with the material as flowable of 0.005～3 weight %, described material is selected from least a in SBR latex, SR latex, NR latex, epoxy resin solution, polyurethane solutions, acrylic acid solution, EVA solution and the pitch, they each all is in emulsion state (wherein having added water and emulsifier), so prepares the elastomeric material that is used for laying road of the present invention.
The elastomeric material that makes like this is applied on the paving of bituminous concrete or cement concrete road in the mode that sprays.Particularly, adopt flexible pipe or aerograph that elastomeric material is sprayed on the covering of roadway, use the rolling machine compacting then or its surfacingization.In the process of this elastomeric material of spraying, preferably with 1～5kg/m
2Ratio this elastomeric material is sprayed on the surface of road.
Equally, when the amount of the flowable that uses in this operation was less than 0.005 weight %, the flow effect that the elasticity fragment is fully separated each other descended, and causes the laying ability that reduces.On the other hand, when the amount of flowable during greater than 3 weight %, elastomeric material too dilutes, and demonstrates the bonding force of reduction after sclerosis, and its intensity also reduces.Especially, when elastomeric material of the present invention when other paver mixes, preferably use flowable with the amount of 0.005～1 weight %.When independent spraying elastomeric material of the present invention, use flowable with the amount of 1～3 weight %.This is to need higher flowability on the road because be sprayed directly into.
In spraying during elastomeric material of the present invention, in order further to improve bonding force and intensity, on the basis of the elastomeric material of 1 weight %, can also use 2 weight % or cement still less.In addition, crackle produces and the enhancing distortion strength in order to suppress, and for example can use fortifying fibre: PE, PP or cellulose.In order to shorten firm time, can add methyl alcohol.And, as required, can use waterproof agent and hydrophober, also can use flyash or silicon ash.Be far infrared radiation or environment protecting, also can sneak into an amount of loess, laterite, kaolin, smolmitza (black clay), beautiful (jade), light English spot stone or coal.For painted, can add an amount of pigment.
When laying elastomeric material of the present invention, at the covering of roadway that will spray elastomeric material (particularly bituminous concrete) is in the situation of laying recently, when road paving temperature was 30～100 ℃, in case elastomeric material of the present invention spraying and compacting then, vehicle was with regard to P Passable.Yet, at room temperature spray elastomeric material and to covering of roadway or with it, spray in the situation on the cement concrete that has hardened, preferably after the elastomeric material sclerosis of spraying 24 hours, vehicle is just current.In the situation of covering of roadway under being in room temperature or the cement concrete that has hardened, when with elastomeric material of the present invention to be heated to state when spraying of 30～100 ℃, the sclerosis cycle can shorten.
In having the drainage pavement of noise reduction, elastomeric material of the present invention can be using with the form of the other mixtures of material that is used for the porous surface layer, thereby make the noise reduction maximization.That is, when elastomeric material of the present invention uses with the material that is used for porous link table surface layer, be filled with this elastomeric material in the hole of aggregate, and therefore surface course deliquescing, finally make the noise reduction maximization.And, when the hole of the aggregate of porous surface layer is filled with elastomeric material of the present invention (in the drainage pavement situation), because the flexibility of covering of roadway, noise reduction can be kept for a long time effectively, even the surface pore is filled by impurity after the long duration.In this case, based on the material that is used for porous link table surface layer of 1 weight %, the content of preferred elastomeric material of the present invention is 1～10 weight %.When the content of elastomeric material of the present invention was less than 1 weight %, hole can not fully be filled.On the contrary, when its content surpassed 10 weight %, its effect no longer increased, and economic benefit also can variation.
When laying general bituminous concrete or having surface course based on the bituminous concrete of the particle size distribution of gap grading (gap grade), when adopting elastomeric material of the present invention with form with another mixtures of material, the elasticity chip distribution is in the surface course of bituminous concrete, thereby obtain soft the laying, improve impact absorption and rideability thus, and realize noise reduction (noise has reduced by 2～5 decibels).

Embodiment 2
Made up 4 kinds of covering of roadways that 100m is long, each all is that 3.5m is wide.
Paving A is the bituminous (bitumen)concrete pavement of common dense-grade, and the aggregate of its use has the maximum size of 13mm, and paving B is a drainage pavement, and the aggregate of its use has 13mm maximum size; Paving C is to use maximum size to be the aggregate of 13mm and to have paving based on the particle size distribution of gap grading, its surface course is made up of paver that is used for it and elastomeric material of the present invention, and paving D is such paving: wherein use with paving C in identical asphalt concrete material laying surface course and elastomeric material of the present invention further sprayed on the surface course.
The elastomeric material that makes among the elastomeric material that uses in the present embodiment and the embodiment 1 is identical.In the present embodiment, following table 2 has provided comprehensive (synthetic) particle size distribution of the aggregate that is used among paving A, B, C and the D.
Table 2
The comprehensive particle size distribution of aggregate
Following table 3 has provided the mixed proportion of the material of the bituminous concrete that uses in the present embodiment.
Table 3
The mixed proportion of the material of bituminous concrete
By table 3 obviously as can be known, the proportion of aggregate (specific gravity) is 2.685, and pitch is 1.02, and limestone powder is 2.892.Equally, the proportion of additive therefor is 1.0 among the drainage pavement B, and the proportion of additive therefor is 0.82 among low noise paving C and the D.The additive that is used for drainage pavement is the improver of mainly being made up of SBS, and the additive that is used for low noise paving C and D is an elastomeric material of the present invention.
According to above-mentioned mixed proportion, with method laying road commonly used.In the D of paving, when the temperature of surface course is 90 ℃, with about 2kg/m
2Ratio the elastomeric material of embodiment 1 is sprayed on this surface course.That is, in the present embodiment, in the laying of the surface course of low noise paving D, comprise elastomeric material of the present invention as additive in its paver, this elastomeric material further is sprayed onto on its surface course.
