Description
Technical field
The utility model is related to highway technical field, more particularly to a kind of cracking resistance drain type asphalt road surface.
Background technology
Semi-rigid asphalt pavement is the main pavement structure of China.Because the temperature deformation of semi-rigid type base is larger,
In the area that China's major part temperature difference is larger, (by a winter) with regard to Mass Cracking after the completion of bitumen pavement construction, and split
Seam is in irregular shape, change width is big, and very big inconvenience is brought to highway maintenance, causes road surface to produce other early diseases, shadow
Road operation is rung, safe mass hidden danger has been buried to bituminous paving.And in the more area of some rainwater, due to bituminous paving
Drainage performance it is bad, road surface is chronically at wet and slippery state, reduces the service life on road surface, while so that the earth-grasping force of wheel
Reduce and easily trigger traffic accident.
Utility model content
The purpose of this utility model is and a kind of cracking resistance dewatering type for proposing in order to solve shortcoming present in prior art
Bituminous paving.
To achieve these goals, the utility model employs following technical scheme：
A kind of cracking resistance drain type asphalt road surface, including glass fiber asphalt mixed layer are designed, the glass fiber asphalt is mixed
The upper strata that layer is laid on road surface foundation stone layer is closed, the upper strata of the glass fiber asphalt mixed layer is equipped with cracking resistance drainage blanket, described
Cracking resistance drainage blanket includes anti-crack concrete layer and the pervious bed positioned at the anti-crack concrete layer left and right sides, the anti-crack concrete layer
Middle part offer pre- joint-cutting, be embedded with multistory reinforced grid in the anti-crack concrete layer, be provided with the pervious bed vertical
To antipriming pipe, the outer wall of the longitudinal porous pipe is connected with many transverse drains, and the upper strata of the cracking resistance drainage blanket is equipped with
Porous asphalt surface layer.
Preferably, the left and right sides of anti-crack concrete layer is provided with concrete arc protective layer, and protective layer and
Pervious bed is bonded.
Preferably, filled with cementation of fissures layer in the pre- joint-cutting, cementation of fissures layer is pitch packed layer.
Preferably, the pervious bed is the artificial masonry layer of water penetration.
The utility model proposes a kind of cracking resistance drain type asphalt road surface, beneficial effect is：The foundation stone layer upper berth on road surface
Cracking resistance drainage blanket is provided with, cracking resistance drainage blanket includes anti-crack concrete layer and the pervious bed positioned at anti-crack concrete layer both sides, cracking resistance
Longitudinal pre- joint-cutting is offered in the middle part of concrete layer, pitch is filled with pre- joint-cutting so that anti-crack concrete layer has stronger
Anti-cracking performance, while anti-crack concrete layer in set with reinforcing bar grid, set reinforcing bar grid improve anti-crack concrete layer
Bulk strength, prevent because road surface foundation stone layer sedimentation cause anti-crack concrete layer cracking, further improve bituminous paving
Anti-cracking ability, be respectively arranged with longitudinal porous pipe and transverse drain in pervious bed, the moisture that porous asphalt surface layer absorbs
Can be arranged to both sides of the road by longitudinal porous pipe and transverse drain, improve the drainability of the bituminous paving, cracking resistance row
Water type bituminous paving contrasts existing bituminous paving has a stronger anti-cracking ability, long service life, and can be effective
The moisture that road surface is gathered is arranged to both sides of the road, it is to avoid road surface slippery situation triggers traffic accident, security performance is high.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of cracking resistance drain type asphalt road surface structural representation.
In figure：1 road surface foundation stone layer, 2 glass fiber asphalt mixed layers, 3 cracking resistance drainage blankets, 4 anti-crack concretes layer, 5 pre-cut
Seam, 6 cementation of fissures layer, 7 reinforcing bar grids, 8 pervious beds, 9 longitudinal porous pipes, 10 transverse drains, 11 porous asphalt surface layers, 12 protections
Layer.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
Reference picture 1, a kind of cracking resistance drain type asphalt road surface, including glass fiber asphalt mixed layer 2, glass fiber asphalt are mixed
The upper strata that layer 2 is laid on road surface foundation stone layer 1 is closed, the upper strata of glass fiber asphalt mixed layer 2 is equipped with cracking resistance drainage blanket 3, cracking resistance
Drainage blanket 3 includes anti-crack concrete layer 4 and the pervious bed 8 positioned at 4 left and right sides of anti-crack concrete layer, anti-crack concrete layer 4
Middle part offers pre- joint-cutting 5, and filled with cementation of fissures layer 6 in pre- joint-cutting 5, cementation of fissures layer 6 is bitumen layer, embedded in anti-crack concrete layer 4
There is multistory reinforced grid 7, the bulk strength that reinforcing bar grid 7 improves anti-crack concrete layer 4 is set, prevent because of road surface foundation stone layer 1
Settle and cause anti-crack concrete layer 4 to ftracture, improve the anti-cracking ability of the bituminous paving.
Longitudinal porous pipe 9 is installed, the outer wall of longitudinal porous pipe 9 is connected with many transverse drains 10 in pervious bed 8, resists
The upper strata for splitting drainage blanket 3 is equipped with porous asphalt surface layer 11, and pervious bed 8 is the artificial masonry layer of water penetration, is set respectively in pervious bed 8
10 drainpipes of longitudinal porous pipe 9 and transverse direction are equipped with, the moisture that porous asphalt surface layer 11 absorbs can be by longitudinal porous pipe 9 and transverse direction
The row of drainpipe 10 improves the drainability of the bituminous paving to both sides of the road, it is to avoid road surface slippery situation triggers traffic accident, safety
