Description
Technical field:
The utility model relates to a kind of Novel cold regeneration asphalt pavement structures.
Background technique:
It is to carry out being laid with road surface, the cost of cold recycled asphalt using cold recycled asphalt that existing highway pavement, which has some,
It is low, but anti-aging property is not so good as heat regeneration asphalt, so when being laid with road surface using cold recycled asphalt, the mass of foundation on road surface
It is better, the long service life of cold recycled asphalt can be made；But there is the phenomenon that very ponding on existing road surface, ponding will reduce
The service life of cold recycled asphalt.
Summary of the invention:
The purpose of the utility model is to provide one kind, and the ponding on road surface can be made quickly to exhaust, and extending cold recycled asphalt makes
With the Novel cold regeneration asphalt pavement structure in service life.
Above-mentioned purpose is realized by following technical scheme:
A kind of Novel cold regeneration asphalt pavement structure, composition includes: soil layer, and the top of the soil layer is laid with bed course,
The top of the bed course is laid with base, and the top of the base is laid with cold recycled asphalt and combines road surface, the cold renewal
Pitch combination road surface, the bed course, the base are provided with the water seepage hole communicated, and the water seepage hole is inserted into soakaway trench, institute
The bottom for the soakaway trench stated connects lower funnel, and the top of the soakaway trench connects upper hopper, and the tip circle of the lower funnel is straight
Diameter is less than bottom circular diameter, and the outside diameter circle of the upper hopper is greater than bottom circular diameter, and the top of the upper hopper covers sieve,
Top surface 1cm of the sieve lower than the cold recycled asphalt combination road surface.
The junction of the Novel cold regeneration asphalt pavement structure, the soakaway trench and the upper hopper passes through steel
Silk screen connection, the top of the soakaway trench pass through the mesh of the steel wire, and the lower funnel is embedded in the soil layer
Interior, the steel wire is located at the cold recycled asphalt and combines road surface.
The Novel cold regeneration asphalt pavement structure, the cold recycled asphalt combination road surface includes cement stabilized macadam mixing
Layer, the bottom connection of the cement stabilized macadam mixed layer base, the top of the cement stabilized macadam mixed layer connects water
The top of mud the hoggin grass root, the cement soil additive connects asphalt concrete cutting optimal,
Surface layer in the top connection asphalt concrete of the asphalt concrete cutting optimal, the asphalt concrete
The top of middle surface layer connects cold recycled asphalt supercrust, the upper hopper be located in the asphalt concrete surface layer with
In the cold recycled asphalt supercrust, the soakaway trench penetrates the bed course, the base, the cement stabilized macadam
Mixed layer, the cement soil additive, the asphalt concrete cutting optimal.
The utility model has the advantages that
1. the outside diameter circle of the upper hopper of the utility model is smaller, generally between 4-8 cm, surface area is small, and low
It is not easy to be subject to crushing in cold recycled asphalt supercrust, infiltration effect is good, can make cold recycled asphalt supercrust not ponding, and rain
Snow-broth will not enter other levels other than soil layer, can greatly extend the service life of cold recycled asphalt supercrust.
The phenomenon that sieve of the utility model can stop sundries to enter upper hopper, soakaway trench is avoided to be blocked, infiltration
It is smooth, effect is good.
The steel wire of the utility model can be good at the position between fixed soakaway trench, seep during being laid with highway
Water pipe is not easy skew, be able to maintain infiltration it is unimpeded, increase the ability of infiltration.
The cold recycled asphalt supercrust of the utility model can greatly reduce cost of building the road, and can accelerate to build the road
Speed, using effect are very good.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of this product.
Specific embodiment:
Below in conjunction with the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description.
Embodiment 1:
