In highway engineering, bituminous paving is a kind of most commonly seen pavement structure, in bituminous paving during one's term of military service, due to road
Bituminous paving will appear crack under the action of the various factors such as face locally settles, freezes disaster, overload rolls.These cracks are not if
Punishment in time, over time, base's even roadbed of middle face layer can be all softened, and generate purt slurry, check crack, depression, faulting of slab ends, so as to
Accelerate the destruction of road pavement.So it needs timely to repair damaged asphalt pavement crack.
According to industry companion, the method for repairing and mending of prior art fracture is broadly divided into the hot method cementation of fissures and the cold process cementation of fissures.
The so-called hot method cementation of fissures refers to, the gap-grouting material for solid or thick liquid under room temperature is used, by heating equipment to cementation of fissures material
Material is heated in advance, and usual gap-grouting material requires heat to 150 DEG C or more, after viscosity is substantially reduced, and can just pour into crack.It fills
After entering, with the reduction of temperature, since road surface is low-temperature condition, the viscosity of Embedding Material will increased dramatically again, so it is difficult to oozing
Thoroughly in the bituminous paving of crack both sides, one can not be formed with old bituminous paving, bad adhesion is easily split again

Slit width degree<It is repaired in 3 millimeters of slight crack；Secondly as emulsified asphalt directly is poured into crack, emulsified asphalt pours into
It measures small, emulsified asphalt can not be made to be completely filled with entire crack and its periphery gap, be not achieved and be closed completely crack and periphery gap
Purpose；Third, due to being the simple cementation of fissures, it is limited that emulsified asphalt oozes down flowing velocity in a short time, fills discontented phenomenon and dashes forward
Go out, and be difficult to observe by, but after military service, with the change of time and environment, the height for stitching internal emulsification pitch just can be apparent
It reduces, and over a period to come, with the extension of time, the height of material can continue to reduce in seam, therefore, existing cold process fills
Bituminous paving after seam punishment often can shortly occur crack again after maintenance at crack；The reason is that, gap-grouting material
Intensity far below asphalt pavement material, the phenomenon that therefore, usage time is short, needs repeatedly to repair, and life-cycle maintenance costs is high.
As it can be seen that existing cold process Slit-pouring Technology, it is impossible to play the performance advantage of emulsified bituminous materials, repair efficiency is poor.
More than technical problem is also a kind of commonplace technical phenomena present in existing technology, existing technology hand
It is related in volume to introduce scheme of introducing that is more, but not providing relatively good, the present invention be exactly from it is above-mentioned the problem of, carry
Go out a kind of better solution.
