Abstract
The utility model belongs to the technical field of road engineering, a rural highway road surface structure of ride comfort is related to, lay extremely thin wearing and tearing layer and rectangular cement concrete plate on pavement base in proper order including top -down, extremely approach between wearing and tearing layer and the rectangular cement concrete plate and all laid the tie coat between rectangular cement concrete plate and the pavement base, extremely thin wearing and tearing layer adopts the synchronous surface dressing construction to form by SBS modified asphalt and rubble. The utility model provides a rural highway road surface structure of ride comfort, this road surface structure can adapt to the rural highway traffic load characteristics, can improve rural highway's ride comfort nature moreover, reduces the rural highway whole life cycle cost.
Description
Technical field
This utility model belongs to road engineering technical field, is related to a kind of pavement structure, more particularly to a kind of ride comfort
Rural road pavement structure.
Background technology
With the development that highway in China is built, Country Road Construction is increasingly paid attention to by country and local government, such as
What further improves rural road pavement performance progressively becomes the problem of each side's concern.Due to Country Road Construction face all the time
Face the deficient problem of investment, often using the cement pavement that cost is relatively low, such as " cement concrete slab of 20cm+semi-rigid base
The version of layer ", as the driving comfort of cement pavement is poor, largely have impact on Public Traveling experience.
Utility model content
The purpose of this utility model is to provide a kind of rural road pavement structure of ride comfort, and the pavement structure can be fitted
Answer rural highway traffic loading feature, and the driving comfort of rural highway can be improved, reduce week rural highway life-cycle
Current cost.
For achieving the above object, this utility model is adopted the following technical scheme that：
A kind of rural road pavement structure of ride comfort, it is characterised in that：The rural road pavement of the ride comfort
Structure includes very thin wearing course and the cement concrete slab being laid on successively on sub-surface from top to bottom；The very thin abrasion
Tack coat is equipped between layer and cement concrete slab and between cement concrete slab and sub-surface；The very thin abrasion
Layer is formed using synchronous surface dressing construction by SBS modified pitch and rubble.
Preferably, the thickness of the very thin wearing course of this utility model employing is not more than 15mm.
Preferably, the thickness of the cement concrete slab of this utility model employing is not more than 18cm.
Preferably, the sub-surface that this utility model is adopted is cement stabilized macadam base or lime stabilization rubble base
Layer, the thickness of the sub-surface is 150～200mm.
Preferably, the tack coat that this utility model is adopted is modified emulsifying asphalt tack coat；The spreading of the tack coat
Measure as 0.3～0.6L/m2。
This utility model compared with the prior art, with advantages below and beneficial effect：
This utility model provides a kind of rural road pavement structure of ride comfort, including being laid on successively from top to bottom
Very thin wearing course and cement concrete slab on sub-surface；Between very thin wearing course and cement concrete slab and cement is mixed
Tack coat is equipped between concrete board and sub-surface；Very thin wearing course is using synchronous by SBS modified pitch and rubble
Crushed stone sealing construction is formed.The very thin wearing course adopted by this utility model, with good driving comfort and antiskid safety
Performance, due to thinner thickness, cost is relatively low.The cement concrete for being adopted is the important supporting course on whole road surface.Meanwhile, road
Connected with modified emulsifying asphalt tack coat between each layer in face, it is ensured that interlayer is continuous so that pavement structure is carried as an entirety
For enough bearing capacitys.Prevent and treat simultaneously and ooze under moisture, it is ensured that road surface water stabilizing.
Description of the drawings
Fig. 1 is the structural representation of pavement structure provided by the utility model；
Wherein：
The very thin wearing courses of 1-；2- tack coats；3- cement concrete slabs；4- sub-surfaces.
Specific embodiment
This utility model is further described in conjunction with drawings and Examples, but this utility model is not limited only to down
The embodiment stated.
Referring to Fig. 1, this utility model provides a kind of rural road pavement structure of ride comfort, including from top to bottom according to
The secondary very thin wearing course 1 being laid on sub-surface 4 and cement concrete slab 3；Very thin wearing course 1 and cement concrete slab 3
Between and cement concrete slab 3 and sub-surface 4 between be equipped with tack coat 2；Very thin wearing course 1 is by the modified drips of SBS
Blue or green and rubble is formed using synchronous surface dressing construction.
Wherein, the thickness of very thin wearing course 1 is not more than 15mm；The thickness of cement concrete slab 3 is not more than 18cm；Road surface base
Layer 4 is cement stabilized macadam base or lime stabilization crushed rock base course, and the thickness of sub-surface 4 is 150～200mm.Tack coat 2 is
Modified emulsifying asphalt tack coat；The spreading amount of tack coat 2 is 0.3～0.6L/m2。
