Description
Technical field
The present invention relates to road engineering pavement structure, pavement structure is ordered more particularly, to a kind of low cost environment-protecting long-life.
Background technology
Existing Perpetual Pavements Structural, form is single, and only considers the service life of pavement structure, generally carrying
The pavement performance of compound high increases the thickness of structure sheaf as technological means, is such as replaced using high performance SMA mixture
AC compounds, or by the bottom surface layer of conventional pav structure by 6~7cmAC-25 bituminous concretes be replaced into 1 or 2 layer 8~
12cmATB-25 or ATB-30 Asphalt Stabilized Macadams.Though above-mentioned measure can effectively extend the service life of pavement structure, engineering
Cost increases significantly (when such as using SMA as superficial layer, because directly bearing driving and weather load, it is necessary to using the profound of high-quality
Wu Yan simultaneously adds fiber stabilizer, is required with meeting abrasion；Increase bituminous texture thickness degree, construction costs will be obviously improved), make
Many projects are obtained to hang back Long-life Pavement Structure.And, existing Long Life Pavement to bituminous texture layer by layer between position
Special enhancements are not taken mostly, the interlayer measure of conventional pav is still continued to use, causes the actual effect of some projects because of road
Face structural integrity is not had a greatly reduced quality by force.Therefore, it is necessary to develop a kind of cost relative moderate and can guarantee that service life
Pavement structure form, while in Pavement Structure Design, should with due regard to road surface use function.In the last few years, it is effectively slow
Solution urban heat land effect, raising road surface running vehicle security, part road use OGFC drainage pavements, can play very in superficial layer
The environment protectings such as good draining, noise reduction.
But it is higher that current asphalt pavement structure still suffers from construction costs, the problems such as the feature of environmental protection and not enough service life.
If two kinds of ground surface materials of OGFC and SMA are combined, the making OGFC thin layers on SMA structure sheafs, and to drip
Blue or green structure sheaf interlaminar bonding is strengthened, can not only give full play to the environment-friendly functions such as antiskid, draining, the noise reduction on OGFC road surfaces and
SMA excellent pavement performance, moreover it is possible to while the pavement structure life-span is lifted, strengthens the protection to SMA structure sheafs, appropriate to reduce
The technical requirements for materials of SMA structure sheafs, so that construction costs is reduced, with significant economy, environmental and social benefits.
The content of the invention
The purpose of the present invention is the deficiency to solve existing Long-life Pavement Structure unitary function and involve great expense, there is provided one
New low cost environment-protecting long-life life pavement structure is planted, long-life effect can not only be reached, and construction costs can be reduced simultaneously
Have environment-friendly function concurrently.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of low cost environment-protecting long-life orders pavement structure, the pavement structure be from top to bottom provided with superficial layer, on
Sealing, middle surface layer, adhesion coating, cutting optimal, Sub-sealing Course, semi-rigid type base and gravel-sorted subbase；
Superficial layer is OGFC-10 thin layers；Upper sealing is rubber asphalt fiber synchronous surface dressing；Middle surface layer is to be not spiked with fibre
The rubber powder modified asphalt limestone SMA-20 compounds of dimension；Adhesion coating is SBR modified emulsifying asphalts layer；Cutting optimal is that ATB-30 is common
The mixing bed of material；Sub-sealing Course is rubber asphalt fiber synchronous surface dressing；Semi-rigid type base is Cement Stable Macadam Mixture layer；Level
Roadbed surface is layed in granular sub-base；
The making semi-rigid type base on gravel-sorted subbase, performs Sub-sealing Course on semi-rigid type base, on Sub-sealing Course
Making cutting optimal, performs adhesion coating in the layer below, the surface layer in making on adhesion coating, and sealing is performed on middle surface layer, in upper envelope
Making superficial layer on layer.
Further：
The superficial layer uses thickness 3cm OGFC-10 thin layers；The upper sealing uses the rubber asphalt of 5~10mm of thickness
Fiber synchronous surface dressing；Middle surface layer is mixed using the rubber powder modified asphalt limestone SMA-20 for being not spiked with fiber of thickness 6cm
Material；Adhesion coating uses SBR modified emulsifying asphalts；Cutting optimal uses the common compounds of ATB-30 of thickness 12cm；Sub-sealing Course is using thick
Spend the rubber asphalt fiber synchronous surface dressing of 10~20mm；Semi-rigid type base is broken using the cement stabilizing of thickness 36cm low dosages
Stone compound；Gravel-sorted subbase thickness 20cm.
Compared with the prior art, the present invention has the beneficial effect that：
OGFC functional layers are combined with SMA stress layers, OGFC superficial layers have the environment protectings such as draining, noise reduction, moisturizing,
And road-ability and security are effectively improved, and SMA structure sheafs are protected so that SMA structure sheafs can use lime
Rock and rubber powder modified asphalt without adding of fiber, while pavement performance is not reduced, can effectively reduce SMA structure sheafs into
This；Upper Sub-sealing Course uses rubber asphalt fiber synchronous surface dressing, can significantly improve the globality of pavement structure, improves stress
Environment, increases the service life.Generally, the pavement structure can effectively extend road occupation compared with conventional pav structure
Life-span and curing cycle, cost relative moderate have environment-friendly function concurrently, and environment, economic and social benefit significantly, are answered with preferable
Use prospect.
