Description
Technical field
This utility model is related to field of road, particularly a kind of pavement structure.
Background technology
Asphalt concrete pavement is a kind of road surface common in life.It is that Jing artificial selections have certain gradation composition
Mineral aggregate and a certain proportion of bitumen for road use material.But because the uppermost structure in conventional pitch concrete road surface mostly is particulate formula
Dense-graded asphalt concrete upper layer, and particulate formula dense-graded asphalt concrete does not possess drain function, causes pavement of road to be arranged
Water effect is poor, when rainwater is larger, it is easy to cause pavement of road hydrops.
For the problems referred to above, notification number provides a solution for the Chinese patent of CN204162964U；
The program is specially a kind of combined type drainage pavement structure suitable for area of heavy rainfull, including base course, described
Cement stabilized macadam layer, framework compact type asphalt concrete layer, the closely knit bituminous concrete of particulate formula are constructed on base course successively
Water barrier and big space Portland Cement Concrete Surface Course；The cement stabilized macadam layer is by rubble, Binder Materials and mortar mixed compaction
Form, the framework compact type asphalt concrete layer is built into framing structure by compact type asphalt mixture, the particulate formula is close
Real bituminous concrete water barrier is fabricated by by the closely knit Colophonium of particulate formula, and the big space Portland Cement Concrete Surface Course is by voidage
15～18% cement concrete is constituted.
Although the pavement structure can improve the drainage effect on surface by filling moisture in pavement structure space,
When rainfall than it is larger when, when the rainwater of sub-surface is penetrated in the pavement structure cannot be discharged to outside pavement structure in time,
May result in road surface and start hydrops, the normal traffic and walk of strong influence vehicle.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of pavement structure, the pavement structure
Quickly the rainwater penetrated among pavement structure can be discharged, it is to avoid occur the situation of surface gathered water when rainfall is larger.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of pavement structure, has constructed successively from the bottom to top base course, permeable formation and permeable surface layer, and the road surface both sides are also
Building has a gutter, the permeable formation and permeable surface layer is permeable with gutter is connected, setting between the base course and permeable formation
There is impervious barrier, the base course top arranges in some continuous connected arches and the junction of adjacent two arch is provided with draining
Pipe, drain pipe one end is connected with permeable formation, and the other end is connected with gutter.
Using said structure, the design of base course top arcuate and the setting of impervious barrier dispersible rainwater in permeable formation point
Cloth, while the junction of adjacent two arch is provided with permeable formation is connected drain pipe with gutter, it is different when rainfall is larger
Rainwater in interval permeable formation quickly can be flowed away to being quickly drained in gutter by drain pipe, while permeable formation and permeable face
The rainwater of both sides also can be penetrated in gutter in layer, and rain water-harvesting cannot in pavement structure during so as to avoiding rainfall larger
Discharge in time, cause road surface the situation of hydrops occur；
Simultaneously base course top is arranged to some continuous connected arches, dispersibles driving and satisfies the need prone pressure, increases
The anti-pressure ability of strong roadbed, and then ensure the service life on road surface.
It is further arranged to the SBS modified pitch that the permeable surface layer is that porosity is 18%-20%.
Using said structure, SBS belongs to styrene analog thermoplastic elastomer, is that styrene-butadiene-styrene three is embedding
Section copolymer, SBS modified pitch is, with matrix pitch as raw material, to add a certain proportion of SBS modifier, by shearing, stirring
SBS is set to be homogeneously dispersed in Colophonium etc. method, it is temperature performance that it can effectively improve Colophonium, tensile property, elasticity, cohesion
Adhesion property, the stability of compound and resistance to ag(e)ing, so as to improve the anti-fatigue ability on road surface, particularly big flow,
There is good adaptability to changes on the serious highway of overload, the permanent deformation on road surface can be reduced, be by designed porosity in addition
18%-20% can ensure that rainwater quickly spreads downwards from road surfaces, it is to avoid road surfaces hydrops.
It is further arranged to the cement stabilized macadam that the permeable formation is that porosity is 11%-13%.
Using said structure, 11%-13% cement stabilized macadams also have good permeable and expansion in addition to stronger bearing capacity
Scattered stress, a carrying transitional function, and material source is extensively, the rainwater for ensureing the permeable surface layer of road table permeates rapidly to permeable formation.
The impervious barrier is further arranged to for HDPE antiseepage film.
Using said structure, HDPE antiseepage film is also referred to as density polyethylene film with high, and the polymer is non-hygroscopic and with well
Water-resisting property, its excellent elasticity and deformability make it be highly suitable for expansion or shrinkage basal plane, can effectively overcome basal plane
Differential settlement, while with good thermostability and tolerance to cold.Chemical stability is good, with higher rigidity and toughness, machine
Tool intensity is good, and resisting environmental stress and cracking is good with tear-resistant strength character, therefore can guarantee that the rainwater of permeable formation will not expand to base course
Dissipate.
It is further arranged to be provided with permeable geotextile layer between the permeable formation and permeable surface layer.
Using said structure, permeable geotextile layer has certain intensity, can further reinforce the permeable face of road table
Layer, improves the bearing capacity on road surface and the rutting resistance of permeable surface layer, and water and soil work is arranged between road table pervious bed and permeable formation
Tissue layer can also prevent road surface thin particulate matter from entering permeable formation.
It is further arranged to the permeable facing surface and is set to the low arc in middle high two ends.
Using said structure, when rainfall is larger, rainwater, can also be with road gradient in addition to it can permeate downwards on road
Towards road surface both sides flow out road surface, be further ensured that road table be particularly in the middle of the table of road be not in hydrops situation.
It is further arranged on the gutter be provided with the cover plate of the arc with filter opening, the centre of cover plate is less than cover plate two
Hold and cover plate side adjacent with permeable surface layer is less than permeable facing surface.
Using said structure, when rainfall is larger, road surfaces to the rainwater that both sides are flowed can be flowed rapidly on cover plate, passed through
Filter opening on cover plate is entered in gutter and flowed away.
In sum, this utility model has the advantages that：
1. the pavement structure draining is quick, and particularly when rainfall is larger, rainwater can pass through the quick discharge path of drain pipe
Face structure, it is to avoid rainwater of the savings in pavement structure cannot in time discharge the situation for causing road surface hydrops occur, affect
Traffic safety；
2. the domed setting in roadbed top and the setting of the permeable surface layer SBS modified pitch in road surface, enhance the resistance to compression of road
Ability, it is ensured that the overall service life in road surface.
