More advantages are used widely on the roads at different levels in China at present.But bituminous pavement is in use, due to for a long time by
Solarization drenches with rain, the climatic effects such as freeze thawing, often will appear various parts along with driving vehicle constantly rolls, on road surface and opens
It splits, pit slot, breakage, the diseases such as crack.The appearance of pavement disease not only reduces the service performance of bituminous pavement, affects road
Normal pass, also increase the probability of traffic accident generation, therefore the various diseases occurred on bituminous pavement had to
It is repaired and is conserved in time.
Traditional asphalt pavement repairing mostly uses hot-mix asphalt mixture to be repaired, but the use of hot-mix asphalt mixture
It is much limited, is not suitable for the small scrappy engineering of project amount such as, is not suitable for the rain and snow weather of low temperature, it is big to apply man-hour requirement
The experienced operator of amount and special-purpose machinery, using flexible is poor, cannot store for a long time, construction cost height etc..In order to solve these
There is pitch cold-repairing material technology again in recent years in problem, but these pitch cold-repairing material technologies respectively have some disadvantages again.
For example, patent CN 201510198290.X proposes a kind of asphalt roads surface layer cold-repairing material, but its material for using
Expect only gravel aggregate, common petroleum pitch and corresponding some cold repairing additives, thus its high-temperature behavior, cryogenic property,
Anti-water damage property, anti-cracking performance etc. is all without significant advantage.
Patent CN 201310280739.8 proposes a kind of road surface cold-repairing material and preparation method thereof, the material used
Only common building stones, No. 70 asphalts and corresponding some cold repairing additives, high-temperature behavior, cryogenic property, water resistant
It damages performance and anti-cracking performance is also general.And two patent applications are all to be used as to gather materials using new building stones, one side cost
It is higher, on the other hand belong to waste of resource.
