Background technology
Bituminous paving is current high grade pavement because it has many advantages, such as that comfortable driving, low noise, maintenance are convenient
Primary structure form.But the bituminous paving of surface compact cannot drain in time in the rainy day, is susceptible to water drift, water mist, increases
Traffic accident incidence.Therefore, we are there is an urgent need to a kind of new pavement structure, to solve existing bituminous paving in rainy day hardly possible
The problem of with Quick drainage.
Utility model content
The purpose of this utility model is to provide a kind of urban road two-layer equation porous asphalt pavement structure, the pavement structures
The rainwater on road surface can be quickly excluded, it is safe in passing through for rainy day to improve automobile.
Technical solution used by the utility model is：
A kind of urban road two-layer equation porous asphalt pavement structure comprising kerbstone, Road System and drainage system；
The Road System includes the porous porous asphalt pavement structure top set gradually from top to bottom, filter layer, more
Hole porous asphalt pavement structure bottom, sealing, waterproof asphalt surface course, the waterproof asphalt surface course are placed in base；
The drainage system includes gutter and the permeable cover board on gutter；
The drainage system is placed between kerbstone and Road System, abuts kerbstone, and be placed in porous drainage asphalt road
Under the structure bottom of face.
By said program, the base is cement stabilized macadam, to ensure the stabilization of pavement structure.
By said program, the waterproof asphalt surface course is dense-graded asphalt concrete.
By said program, the sealing is mainly used to prevent rainwater infiltration, is heated bitumen synchronous surface dressing.
By said program, porous permeable pitch of the porous porous asphalt pavement structure bottom using voidage more than 20% is mixed
Material is closed, grain size is based on the coarse aggregate grading of 10 ~ 20mm, and thickness is 35 ~ 50mm, in order to be oozed under rainwater.
By said program, the filter layer is the grid type geotextile with some strength, with to penetrating porous draining
The rainwater on asphalt pavement structure upper layer is filtered, it is ensured that the smooth discharge of rainwater.
By said program, porous permeable of the porous porous asphalt pavement structure top using voidage more than 15% drips
Green mixture, for grain size based on the fine aggregate grading of 5 ~ 10mm, thickness is 20 ~ 30mm.Using fine grading so that structure hole ruler
Very little smaller, for coarse grading porous structure, noise reduction capability greatly improves.
The beneficial effects of the utility model are：
By the way that porous porous asphalt pavement structure top is arranged, porous porous asphalt pavement structure bottom constitutes two-layer equation and arranges
Bituminous grout pavement structure can quickly exclude down the rainwater oozed, and it is safe in passing through for rainy day to improve automobile；Specially：Porous draining
Sieve pore filtering is played the role of on asphalt pavement structure upper layer, can effectively prevent leaking under big grain size sundries；Porous porous asphalt pavement
Water then can be drained into permeable cover board in time, through permeable lid by structure bottom under flow and Driving Loading by flowing pressure
Plate flow to gutter discharge；
The rainwater on road surface can be quickly excluded, current safety of the automobile in the rainy day is improved, what reduction vehicle traveling generated makes an uproar
Sound creates quiet comfortable urban highway traffic environment.

Layer, 6, porous porous asphalt pavement structure top, 7, gutter, 8, permeable cover board, 9, kerbstone.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
Referring to Fig. 1, a kind of urban road two-layer equation porous asphalt pavement structure comprising kerbstone 9, Road System and row
Water system.Road System includes the porous porous asphalt pavement structure top 6, filter layer 5, porous row set gradually from top to bottom
Bituminous grout pavement structure lower layer 4, sealing 3, waterproof asphalt surface course 2, base 1；Wherein, porous porous asphalt pavement structure top
6 using voidages be more than 15% porous permeable asphalts, grain size based on the fine aggregate grading of 5 ~ 10mm, thickness be 20 ~
OGFC-10 or OGFC-13 can be used in 30mm, porous porous asphalt pavement structure top 6, and material particle size is relatively small, gap
Rate is slightly lower, can form " sieve effect ", prevents big grain size dust, sundries with rainwater infiltration；Filter layer 5 is with some strength
Grid type geotextile, mass area ratio is preferably 300 ~ 500g/m2, can not only improve road surface rutting resistance, but also can be with
Prevent upper layer fine grained from entering porous porous asphalt pavement structure bottom 4；Porous porous asphalt pavement structure bottom 4 is PAC-
13 or PAC-16,20% porous permeable asphalt is more than using voidage, and grain size is with the coarse aggregate grading of 10 ~ 20mm
Main, thickness is 35 ~ 50mm, has the effect of filtering bulky grain dust, falls into dust in its gap, sundries then because of lower layer gap
It is larger, and nature is gone out by flow, has the effect of emptying gap certainly；Sealing 3 is mainly used to prevent rainwater infiltration, is that heated bitumen is same
Crushed stone sealing is walked, spilling pitch by heat forms with the single particle size rubble of synchronous spreading after rolling, and pitch used is that SBS is modified drip
