Description
Technical field
The present invention relates to pavement crack repair Material Field, and in particular to a kind of pitch repaired for asphalt pavement crack
Liquid and preparation method thereof.
Background technology
With developing rapidly for China paving and deck paving technology, bituminous concrete with its function admirable, construction it is simple,
Be easily recycled, low cost and other advantages and be widely used and promote, but the mat formation crack of bitumen layer of the thing followed is asked
Topic is always the focus and difficult point of road circle concern.China's economy is developed rapidly, and the volume of traffic and load-carrying are continuously increased, and pave-load layer exists
About it is to produce than more serious crack disease, particularly damp and hot height in 1~2 year year of open to traffic under the repeated action of heavy duty
Warm area, Rotating fields of mating formation produce serious cracking destruction quickly；Semi-rigid type base that China's expressway surface is used mostly and not
The defect of the disconnected Steel Bridge Deck mechanical property promoted also exacerbates pave-load layer structural damage.Paving structure Crack failure not only influences
The comfortableness of driving and road surface it is attractive in appearance, more had a strong impact on its structural mechanical property and durability；If the microcrack of early stage
If without repairing in time, road table water has an opportunity to enter inside pavement structure, or even in roadbed, produces roadbed uneven
Deformation, to roadbed output destroy, influence roadbed service behaviour；Under the influence of traffic load and periodicity environment, crack
Further development then produces the diseases such as the peeling of aggregate or fritter bituminous concrete, loose, pit, ultimately result in big transverse joint,
The appearance of longitudinal joint, check crack.
Handled mostly using filling technology fracture at present, crack treatment material is roughly divided into three classes, a class is heat
