Abstract
The utility model discloses a kind of long-life cement concrete road structures, from top to bottom successively include cement concrete pavement layer, separation layer, waterproof layer, Asphalt macadam subgrade, underlayment, bed course.Phenomena such as pavement structure described in the utility model can effectively prevent surface water to penetrate into base, and base uses asphalt macadam, will not generate purt mud, plat-bottom escape；Substantially do not occur all kinds of early diseases of current cement pavement, cement pavement and base service life can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of pavement structure, especially a kind of long-life cement concrete road structure.
Background technique
Currently, the base of cement concrete pavement is the stabilization soil structure of semi-rigid class, is influenced by external world's infiltration, in traffic load
Purt mud, phenomenon of coming to nothing easily are generated under effect, and then makes cement concrete slab rupture failure, seriously affect the use function on road surface and are made
Use the service life.
Utility model content
Based on this, the purpose of the utility model is to overcome provide a kind of long-life in place of above-mentioned the deficiencies in the prior art
Cement concrete road structure.
To achieve the above object, technical solution adopted in the utility model are as follows: a kind of long-life cement concrete road structure,
It from top to bottom successively include cement concrete pavement layer, separation layer, waterproof layer, Asphalt macadam subgrade, underlayment, bed course.
Preferably, the cement concrete pavement layer with a thickness of 20~32cm.
Preferably, the separation layer is plastic film layers.
Preferably, the waterproof layer is SBS modified emulsifying asphalt layer.
Preferably, the Asphalt macadam subgrade with a thickness of 8~12cm.
Preferably, the underlayment be semi-rigid class formation, the underlayment with a thickness of 15~25cm.
Preferably, the bed course be graded broken stone, the bed course with a thickness of 15~20cm.
Furthermore it is noted that cement concrete pavement layer, base in herein described long-life cement concrete road structure
Layer, bed course are intended to meet existing technical specification.
Compared with the existing technology, the utility model has the following beneficial effects:
This structure can effectively prevent surface water to penetrate into base, and base uses asphalt macadam, and it is de- will not to generate purt mud, board bottom
Phenomena such as empty；Substantially do not occur all kinds of early diseases of current cement pavement, can greatly prolong cement pavement and base
Service life.
Base semi-flexible in the utility model pavement structure, can be effectively prevented surface water and penetrates into base, it is therefore prevented that
The generation of purt mud, plat-bottom escape phenomenon also can reduce the temperature-warping stress of cement panel generation, can greatly prolong cement
The service life of road surface and base.
Base semi-flexible in the utility model pavement structure reduces pavement structure total thickness compared with traditional structure layer thinner thickness
Degree, can save a large amount of ground surface materials, achieve the effect that energy-saving and emission-reduction.Good effect can also be obtained by applying in " Bai Gaibai " engineering
Benefit.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of long-life cement concrete road structure described in the utility model；
Wherein, 1, cement concrete pavement layer；2, separation layer；3, waterproof layer；4, Asphalt macadam subgrade；5, underlayment；6, bed course.
Specific embodiment
To better illustrate the purpose of this utility model, technical solution and advantage, below in conjunction with attached drawing and specific implementation
The utility model is described in further detail for example.
Embodiment 1

Embodiment 3
A kind of embodiment of long-life cement concrete road structure described in the utility model, long-life cement described in the present embodiment
Concrete road structure is as shown in Fig. 1, from top to bottom successively includes cement concrete pavement layer 1, separation layer 2, waterproof layer 3, asphalt macadam base
Layer 4, underlayment 5, bed course 6；Cement concrete pavement layer 1 with a thickness of 26cm；Separation layer 2 is plastic film layers；Waterproof layer 3 changes for SBS
Property emulsified asphalt layer；Asphalt macadam subgrade 4 with a thickness of 10cm；Underlayment 5 be semi-rigid class formation, underlayment 5 with a thickness of
20cm；Bed course 6 be graded broken stone, bed course 6 with a thickness of 17cm.
This structure can effectively prevent surface water to penetrate into base, and base uses asphalt macadam, and it is de- will not to generate purt mud, board bottom
Phenomena such as empty；Substantially do not occur all kinds of early diseases of current cement pavement, can greatly prolong cement pavement and base
Service life.
Base semi-flexible in the utility model pavement structure, can be effectively prevented surface water and penetrates into base, it is therefore prevented that
The generation of purt mud, plat-bottom escape phenomenon also can reduce the temperature-warping stress of cement panel generation, can greatly prolong cement
The service life of road surface and base.
Base semi-flexible in the utility model pavement structure reduces pavement structure total thickness compared with traditional structure layer thinner thickness
