Description
Technical field
The invention patent relates to a kind of asphalt concrete pavement Slice by slice cutting equipment, this equipment is able to achieve bituminous concrete
Road surface Slice by slice cutting recycling, to make full use of the RAP material of recycling to prepare high performance Recycled Asphalt Pavement.
Background technique
At year ends 2013, statistics display Chinese cement concrete road surface is mainly used for township, in village's low-grade highway, 10.4 ten thousand
In km express highway pavement, cement concrete pavement only has 3452.8km, proportion only 0.19%, asphalt concrete pavement institute
Accounting example is 99.81%, and cement concrete pavement is compared with the mileage quantity of asphalt concrete pavement, almost negligible to disregard.By
In asphalt concrete pavement is convenient with working drawing review with respect to other road surfaces such as cement concrete pavements, road-ability is good, prolongs
Long Life of Tyre saves the advantages such as fuel oil, quick open to traffic, public to year ends 2017 national total mileage of highway 477.35 ten thousand
In middle level Four and ratings above highway mileage up to 433.86 ten thousand kilometers, account for total mileage of highway 90.9%, nearly all use pitch coagulation
Soil surface, the update of original cement, sand-gravel surface, which overlays, also gradually uses Asphalt Concrete Overlay.Urban road is also in this way, mesh
Preceding nearly all urban road all uses asphalt concrete pavement.However, the design service life of asphalt concrete pavement is shorter,
8 ~ 15 years, with the continuous development of logistics, the ratio of Heavy Traffic was increasing, and traffic volume growth rate is also higher and higher, drip
Green concrete road surface early damage is also increasingly severe, and actual use just needs maintenance and renovation for 7 ~ 8 years, and some is even runed 2 ~ 3 years
Begin to the destruction such as crack, pit slot occur.The highway built up successively after the nineties entered it is big or middle repair the phase, hereafter,
There are about 12% bituminous pavement needs to overhaul every year, and Bituminous concrete surface discarding amount is up to annual 2200000 tons, and this number is
Increased with every year about 15% speed, after 10 years, the big or middle old asphalt mixture for repairing generation of bituminous pavement is up to number
Ten million ton.It digs, the asphalt bulk deposition of milling is in both sides of the road and other fixed venues, or useless as garbage loading embeading
It abandons, not only pollutes environment in this way, but also waste valuable resource.One side pitch is the heavier hard-degraded substance of smell, will be caused
Surrounding enviroment seriously pollute；On the other hand new building stones are largely exploited, will lead to forest cover reduction, soil erosion etc. is serious broken
Bad ecological environment, and the significant wastage of resource is caused, as many as 1,500,000,000 yuan of fee of material can be saved every year if through regeneration.Cause
This, the exploitation of research, the popularization and relative special-purpose equipment of asphalt concrete regenerating technology, to reducing the construction costs, protecting ecology
Environment and the resource-conserving to our countries, environmentally friendly amphitypy society and sustainable development highway construction have pole
Big meaning.
Applied of Asphalt Pavement Recycle Technique is comparative maturity in the application of developed country and popularizes.The U.S. is that earliest research uses
The country of asphalt pavement regeneration and reutilization technology, so far from 1976, road surface waste regeneration utilization rate is more than 70%.West Europe
Country also attaches great importance to this technology, the waste asphalt pavement material regeneration rate of European Asphalt road surface association (EAPA) each member state
Reach 100%.All organize the collection and storage work of old pavement material in the almost all of cities and towns of Finland.World Jing He Group in 1997
It knits and detailed investigation has been carried out to 14 national ground surface material regeneration situations, deliver《Road engineering regeneration war
Slightly》White paper points out that the regeneration rate of old bitumen pavement material is 75% ~ 100% in book.Again according to international clean energy resource and environmental protection
Raw administration's statistics, American-European bituminous pavement recycling have reached 80% or more, and Holland, Spain have had reached 100%.According to another report,
External bituminous pavement can be accomplished repeatedly to recycle.
For China's bituminous pavement recycling and reusing rate there are also larger gap compared with American-European countries, pitch regeneration in China's is big at present
Sizable application is also in the starting stage, in " Recycling Old Asphalt Mixture using " project research that the nineteen eighty-three Ministry of Construction assigns,
Light oil appropriate is added in old residual-oil pavement to soften it, mixing and stirring for mixture is carried out using the conventional equipment suitably reequiped, and
In Suzhou, Wuhan, Tianjin, four, Nanjing city making, more than 30,000 square metres of Experiment Road, regenerated road surface is proved through observation
It is comprehensive to be not less than conventional Hot-mix Bituminous Concrete Pavement using quality.And since the late 1980s, along with China
The Large scale construction of high-grade highway, new highway road surface almost no longer consider that, using waste and old ground surface material, pitch regeneration is withdrawn to
Backseat, correlative study popularization are substantially at dead state.Until in recent years, with growth, the budget of national road demand
The reduction of fund, and to the needs of safe and efficient and cost-effective roadnet, the demand that existing road repairs
It increases substantially.National Environmental Protection Agency and expert also appeal that " waste asphalt pavement material is containing the noxious materials such as sweet smell, naphthalene, degradation speed
Slowly, contaminated soil and water source；These obsolete material main components are pitch and basalt, are all non-renewable resources, not good
Good utilisation is sorry blue mountains and green waters ".As bituminous pavement reconstruction, the feature of environmental protection repaired, economy technology-asphalt road plane materiel
In the work schedule of the material regenerative use technology person that refers to highway work again, become the hot issue of highway scientific research.One
A little scientific research institutions and colleges and universities start to carry out the research and extension of hot in-place recycling.For example, 1998, Department of Communications of Handan City introduces
Witt, Germany root company WR2500 regenerating device is changed using one section highway of the situ regeneration technology to Hebei Province for the first time
Make maintenance.2003, introduce in wide Buddhist express highway pavement overhaul U.S. ASTEC company twin-roll pitch regeneration stirring apparatus into
The regeneration of row bituminous pavement, this is the highway projects of the first large-scale application plant-mix heat recycle technology in China, mesh
Preceding behaviour in service is good.But compared with developed countries, the asphalt surface hot reproduction technology in China not yet forms complete material
Appraisement system, mixing proportion design method, construction technology, again generating apparatus and quality control standard, therefore still need to for relevant issues exhibition
Open further further investigation.It is domestic at present to the research of hot in-plant reclaimed old material be concentrated mainly on to old material moisture content, gradation,
The research of bitumen content, the performance for recycling pitch etc., few pairs of former ground surface materials carry out layering recycling and layering research
And obtain the work of valuable conclusion.Chang An University Deng Xiao blueness in its paper by route hierarch milling sample, for
Each layer sample carries out bitumen recovery respectively and has carried out the test of index of correlation, obtains bituminous pavement with its different aging of depth
Degree has significant difference, and surface layer aging is more serious, and with the increase of depth, aging will be more slowly.Xu Ke " is returned in his paper
The Zhejiang Province lake Shen Jia Hangzhoupro highway is had chosen in influence of debit's formula to recycling material of waste asphalt variability " and Hangzhou-Zhejiang high speed is public
The recycling material of waste asphalt acquired when the heavy resurfacing of two highways with typical representative in road is studied, broken material
Milling material when 1-6mm acquisition is from the lake Shen Jia Hangzhoupro highway heavy resurfacing in 2012, milling not divided lane, regardless of structure sheaf；
Milling material 1-6mm is the milling material in Hong Yong Freeway upper layer (3 lane), is the RAP for being layered milling.It is dripped from two kinds of RAP
The testing result of green content obtains, and two groups of RAP Asphalt Contents are significantly different, wherein Hong Yong Freeway upper layer RAP milling
Bitumen content in material is higher more stable, and average content reaches 4.74%, the coefficient of variation 3.1869%, and the lake Shen Jia Hangzhoupro high speed is public
The RAP Asphalt Content average value on road is 3.96%, and the coefficient of variation has reached 5.5% or so, and bitumen content variability is larger, says
Bright layering milling can effectively improve the variability of RAP Asphalt Content；From the bitumen aggregate ratio curve of asphalt reclamation material it can also be seen that
The bitumen aggregate ratio of reclaimed materials without layered shaping will be significantly lower than the bitumen aggregate ratio of the reclaimed materials of layered shaping.As it can be seen that different structure
Bitumen content in the RAP of layer is widely different, so that the performance that will lead to RAP morphs, carries out to same highway
It is layered milling, also has certain help to the uniformity aspect for improving bitumen content.The testing result for performance of gathering materials in RAP is also such as
This, the RAP of Hong Yong Freeway gather materials each test group the discreteness for being sieved through rate it is smaller, and the Shen of not layered milling is good
The discreteness of the rate that is sieved through of gathering materials of the RAP of lake Hangzhoupro highway is obvious, thus illustrates to be layered what milling gathered materials to RAP
Gradation influence is also related, and layering milling can keep the gradation grade on former road surface substantially, does not make gradation that big variation occur.Therefore,
Way of recycling is very crucial to the effective use of reclaimed asphalt mixture.
The equipment of the old asphalt mixture of China's recycling at present is mainly milling machine.Milling machine is Asphalt Concrete Pavement Maintenance
One of capital equipment of construction is mainly used for the excavation renovation of the asphalt concrete pavements such as highway, town road, airport, goods yard,
It can be used for removing the defects of packet, oily wave, reticulate pattern, track are gathered around in road surface, may further be used to excavated pavement pit slot and groove, Yi Jishui
