Description
Technical field
The invention belongs to asphalt field, it is related to a kind of cold repairing asphalt mixture and preparation method thereof.
Background technology
With the swift and violent growth of national economy, transport development is increasingly taken seriously, and highway in China total kilometrage is increasing year by year
Plus, this economic development and national security to China is significant.Ended for the end of the year 2016, highway in China total kilometrage oneself reach
More than 485 ten thousand kilometers, wherein highway accounts for more than the 2.6% of total mileage of highway, has broken through 130,000 kilometers, it is contemplated that the year two thousand twenty bottom I
State's high speed total kilometrage reaches 150,000 kilometers.Due to bituminous paving have safety and comfort, driving noise it is low, be easy to maintenance,
The low feature of fast passing, construction cost, the already main form of mating formation as highway in China and urban road.But it is due to drip
The temperature-sensitive characteristic of green material, in the long-acting process of environmental factor and traffic loading, road surface is gradually damaged and occurs such as splitting
Many diseases such as seam, loose, peeling and pit-hole.If pit occurs in road surface or breakage is punished not in time, single hole may be caused
Groove is transformed into multiple pit bands, and initial microcrack continues to be extended to deep crack, accelerates the breakage of whole pavement structure, not only shadow
Service life of road surface and road-ability are rung, and potential safety hazard can be caused, easily triggers traffic accident.Therefore road pavement pit
Timely repairing turn into the emphasis that highway routine servicing works, current repairing technique has two kinds of hot repair reinforcing method and metalock to repair
Mend technique.The former patching material uses hot-mix asphalt mixture, material source extensively, technology maturation, pit is more concentrated, quantities
Larger road surface obtains good repair efficiency.But for repairing amount is small, place scattered, the pavement patching of salvaging etc., it is special
Be not can undoubtedly be increased using hot repair reinforcing method temperature is relatively low and spring, the winter of sleety weather maintenance work difficulty and into
This, while repairing quality also cannot be guaranteed, this just to timely, effective, safe and environment-friendly pit repairing new material, new technology,
New technology has researched and proposed an urgent demand.Cold repair technology is to solve one of effective means of this engineering roadblock, the repairing material
Material mixing can be stored in advance, and it has the advantages that environmental protection, construction are quick, repairing quality is high, rapid open to traffic；And
Cold repair compound is a kind of round-the-clock patching material, is not limited by environmental condition and transportation condition, can in low temperature and
Road pavement pit in time, efficiently repair under sleet environment, has obtained being widely recognized as domestic and international pavement maintenance management department.
There is larger limitation using hot-mix asphalt mixture to pit repairing, and cold-patch compound and bituminous paving caking property it is good and
Excellent working performance, the repairing defect of hot-mix asphalt mixture is reduced or overcomes at many aspects.At present both at home and abroad to cold-patch
Material has done a lot of research and application, achieves more significant achievement, but still suffer from some problems：External asphalt cold repairing production
Product function admirable, but price is high, introduces key technology and is limited with product promotion；Cold repairing asphalt mixture is produced on domestic market
Product are uneven, and performance is not sufficiently stable, and generally existing early strength is low, shaping speed slow, poor durability, service life
The performance short slab such as short；To the not deep enough comprehensive system of research of asphalt cold repairing material, evaluation method to cold asphalt mixture performance and
Technical indicator is not enough unified, and lacks relevant industries standard or regulation, and a series of this reason significantly limit cold paving technique in road
Popularization and application in the maintenance project of road.
