Description
Technical field
Road and bridge pavement technique field is the utility model is related to, particularly a kind of Rubber-Asphalt Pavement structure.
Background technology
Rubber asphalt（Asphalt Rubber）It is a kind of effective way for reducing junked tire " black pollution ".Due to rubber
The rubber powder content mixed in glue asphalt binder is larger（Typically will be more than 15%）, so junked tire can be utilized effectively
Resource, substantially reduce environmental pollution and save the engineering materials such as pitch.And rubber asphalt concrete has asphalt concrete
Incomparable advantage：Superior high temperature performance, rutting resistance is strong, high anti-aging, antioxygenic property, good endurance and
Low noise etc..
At present, rubber asphalt is prepared mainly by the way of live wet method, but scene processing is limited by place capacity, every time
The quantity of shear agitation is in 1 ~ 2 t, and this process needs to burn the energy to provide heat, and compare batch production scale operation,
Workshop-based production can undoubtedly produce more pollution problems；Due to the limitation of rubber asphalt production capacity, what road surface was constructed on a large scale
Construction plan tissue difficulty is big.
In addition, also finished product wet method rubber asphalt, finished product rubber asphalt factorial praluction make up the limitation of scene processing
And environmental problem, higher rubber powder volume and viscosity improve pavement quality.But there is also production for finished product wet method rubber asphalt
Technique is complex, it is necessary to which asphalt production manufacturer possesses more kettles, more mill premixing systems can produce the drip of finished product wet method rubber in batches
This blue or green problem, moreover, big for the rubber asphalt dosage demand of small lot, operation difficulty.
For the application of larger range of promotion rubber asphalt, intend by the vulcanization to waste old material, plasticizing and continuous
The processing such as granulation, is made rubber powder modified agent by waste rubber powder, is then processed into rubber asphalt with matrix pitch again.Process equipment
Conventional SBS equipment for processing modified asphaltum and machining production line are directly used, pitch manufacturer is without transforming equipment, rubber drip
Blue or green preparation technology is easier.The rubber asphalt of production not only has the advantages of finished product wet method rubber asphalt, and application is more
Extensively, this is for the little Trunk highway transformation of current district one-level quantities and county road medium-capital overhauling engineering, this kind of mode
It is more flexible.
In order to preferably embody the superiority of rubber powder modified agent rubber asphalt concrete, it is necessary to study a kind of new road
Face surface layer structure.
The content of the invention
Main purpose of the present utility model is, the defects of overcoming existing pavement surface structure to exist, and provides a kind of
Novel pavement surface layer structure, construction costs is reduced, rationally using resource, thus more suitable for practicality, and with the profit in industry
With value.
The utility model is realized using following scheme：
Rubber-Asphalt Pavement structure, from lower to upper, successively by roadbed, sub-surface, road surface cutting optimal and road surface
Composition.
Preferably, the road surface and road surface cutting optimal thickness are 4 ~ 6cm.
Preferably, the road surface is rubber powder modified agent rubber asphalt particulate formula asphalt concrete layer.
Described rubber powder modified agent rubber asphalt particulate formula bituminous concrete is by the new aggregate of basalt, miberal powder, rubber powder modified
Agent rubber asphalt is formed, and rubber powder modified agent volume is 20% in rubber powder modified agent rubber asphalt（Mix outside）.
Preferably, described road surface cutting optimal is grain formula asphalt concrete layer in rubber powder modified agent rubber asphalt.
Grain formula bituminous concrete is by the new aggregate of limestone, miberal powder, rubber powder modified in described rubber powder modified agent rubber asphalt
Agent rubber asphalt is formed, and rubber powder modified agent volume is 20% in rubber powder modified agent rubber asphalt（Mix outside）.
Preferably, rubber powder modified agent rubber asphalt therein is to pass through advanced treating using rubber powder（Vulcanization, plastify and connect
The processes such as continuous granulation）Later novel rubber powder modifying agent, the processing modified rubber asphalt formed added in matrix pitch.
Preferably, the graphene oxide that one layer of 2 ~ 5mm is also laid between described road surface and cutting optimal is modified drip
Cyan layer.
The grain formula pitch in rubber powder modified agent rubber asphalt particulate formula asphalt concrete layer and rubber powder modified agent rubber asphalt
It one layer of graphene oxide modified pitch is re-layed among concrete layer on the one hand can save the higher graphene oxide of cost and change
Property pitch dosage, another aspect graphene oxide modified pitch has the high-temperature behavior of highly significant, resistance type ability, only needs
Add a small amount of graphene oxide modified pitch can and greatly improve asphalt pavement rut resisting ability.
Preferably, described sub-surface is cement stabilized macadam base.
Beneficial functional of the present utility model is：
1st, pavement structure of the present utility model possesses more superior high temperature performance, anti-car compared to traditional pavement structure
Rut ability is strong, high anti-aging, antioxygenic property, good endurance and low noise etc..
2nd, the rubber powder modified agent rubber asphalt that the utility model uses is to use a kind of rubber powder as by advanced treating mistake
New rubber powder modified agent afterwards, the rubber asphalt formed is modified by certain processing technology added in matrix pitch.Pin
The problem of existing to current rubber asphalt production preparation method and construction organization etc., actively utilizes rubber powder modified agent rubber
Pitch develops arterial highway top course material, can not only ensure the excellent pavement performance in arterial highway road surface, simplifies simultaneously
The production technology of rubber asphalt, reduces rubber-asphalt mixture difficulty of construction, improves the flexibility of construction organization.Separately
Outside, moreover it is possible to take full advantage of waste and old resource, reduce the land seizure of waste old, avoid dirt of the processing mode to environment of burning
Dye, has important environmental benefit.
3rd, pavement surface structure of the present utility model, construction costs is reduced, rationally using resource, thus more suitable for reality
With, and with the value in industry.
