Description
Technical field
The present invention relates to city secondary distributor road and branch road construction field, more particularly to a kind of water permeability asphalt concrete road and
Its construction method.
Background technology
Gradable town road is through street, trunk roads, secondary distributor road, branch road.Road surface form mainly divide bituminous paving and
Concrete road surface, because function path is had nothing in common with each other, therefore the construction method of road should also be treated with a certain discrimination.Through street and major trunk roads
Vehicle flowrate is big, and vehicle is more, and speed requires high；And subsidiary road, although branch road vehicle flowrate is also big, vehicle it is many based on dolly and
Pedestrian and other Portable traffic instruments are in occupation of circulation main body, and this requires subsidiary road, and branch road can possess sqouynd absorption lowering noise, draining
Water is controlled, the function of damp-warm syndrome is adjusted.
Traditional pitch and cement concrete construction technology being used current road construction more, and because the change of weather is extreme
Weather occurs often.Such as long term high temperature causes urban heat land effect rapidly to aggravate, suddenly rain cats and dogs so that urban ponding very
To waterlogging.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, present invention aims at propose a kind of water permeability asphalt concrete road
And its construction method, so as to solve the problems, such as city ponding, alleviate tropical island effect.Collect the effect that Natural Water tentatively reaches control water control temperature
Really, city noise is alleviated to a certain extent.Increase substantially life of urban resident comfort level.
In order to achieve the above object, the technical scheme that the present invention is provided is as follows：
A kind of water permeability asphalt concrete road, including arch slope ground 10, the surface of arch slope ground 10 are provided with
Plain soil layer 9 that is levelling and being compacted is provided with impermeable stratum 6, impermeable stratum 6, the plain top of soil layer 9 sets multistage with gravelly soil 4,
Top of the multistage with gravelly soil 4 sets grittiness to lay compacted lift 3, and the top of gravel laying compacted lift 3 is provided with road deck,
Coarse Graded Bituminous Concrete 2 is included, Coarse Graded Bituminous Concrete 2 is laid on the top that gravel lays compacted lift 3, and coarse grain formula pitch is mixed
The top asphalt compound 1 of solidifying soil 2.
It is described plain soil layer 9, multistage mixed with gravelly soil 4, gravel laying compacted lift 3, Coarse Graded Bituminous Concrete 2 and pitch
Close material 1 and be provided at both ends with drainage.
Described drainage be divided into above and below two layers, the inner side of drainage uses coarse porous concrete 7, the outside of drainage and upper
Use below in normal concrete 8, the high 60cm of draining unexposed layer internal diameter, the high 40cm of drainage lower floor drainage internal diameter, drainage
The a width of 40cm in footpath.
Described gravel laying compacted lift 3 uses 15-30cm gravels.
Thickness of the described multistage with gravelly soil 4 is 15-30cm, and multistage uses 0-10mm Stones with gravelly soil 4:
10-20mm Stones:30-40mm Stones:40-50mm Stone=2:2:5:9 mixing.
The real coefficient of described plain soil layer 9 is 0.92.
A kind of construction method of water permeability asphalt concrete road, its step is：
Step one：Compacting foundation after the deep construction foundation pits of 120cm, excavation is excavated, overarch slope slope to the plain soil of backfill
Coefficient is 5%, and impermeable stratum is done on its surface, using tar seal；
Step 2：Cushion construction：It is that 5% back fill course looks for slope that first paving, which fills out a laminin rammed earth by script gradient coefficient, is repaiied
Whole gradient coefficient is 1.2% -2%, rammed earth coefficient 0.92；Then will stir in advance the multistage that makes with gravelly soil (0-
10mm Stones:10-20mm Stones:30-40mm Stones:40-50mm Stone=2:2:5:9) insert
30cm is thick and is compacted；
Step 3：Base layer construction：Particle diameter is laid to be compacted for 15-30cm gravels；
Step 4：Surface construction：Surface layer lower floor directly lays 8cm finished products Coarse Graded Bituminous Concrete and is compacted, on surface layer
Layer laying finished product OGFC asphalts pavement thickness is compacted for 2cm；
Step 5：Drainage is constructed：Cushion construction, basic unit are applied is provided with prefabricated drainage with the both sides of work surface construction.
Beneficial effects of the present invention：
1st, drainage can consolidate holding basic unit, and the soil of bed course is not washed loss, so as to ensure that spacer structure is constant, protect
Demonstrate,prove road capacity constant；
2nd, arch slope ground can effective draining；
3rd, plain soil layer, multistage gravelly soil, Coarse Graded Bituminous Concrete and the asphalt compound of matching somebody with somebody can alleviate heat island effect
City noise, should be alleviated to a certain extent and improve comfort level.
