Description
Technical field
The present invention relates to concrete road care fields, more particularly to a kind of concrete road conserving material and its answer
With.
Background technique
With the development of economy and social progress, the super highways such as highway, the state highway in China are whole
It is laid with using bituminous concrete, asphalt concrete road is not only beautiful and clean, but also more flat, drives a vehicle more comfortable, but mesh
The common asphalt concrete road thermal adaptability of preceding major part is poor, thus often crannied appearance, if these cracks
It repairs not in time, crack will expand over time, and more serious destruction is caused to asphalt concrete road, influences road
Performance and service life.
It is general using viscous benefit and joint filling especially for the repairing in crack at present for the maintenance of asphalt concrete road
Two ways, and in both modes, viscous benefit use widest in area, are called to the viscous material mended in asphalt concrete road crack
Pressing belt, pressing belt are generally made of asphalt material, existing pressing belt using when need to heat mostly pressurization can just be adhered to
Very complicated on road surface, although also there are some pressing belts directly pasted without heating, this pressing belt is often adhered to
Property is poor, with the variation of vehicle rolled with environment after repairing, will be detached from road surface quickly, but also it is further to will cause crack
Ground, which extends, to be expanded, and the practicability is poor.
Therefore, a kind of concrete road conserving material and its application are needed, existing asphalt concrete road is able to solve and splits
Conserving material is stitched using cumbersome, cannot be persistently adhered at crack, or even also will cause crack and further extends the problem of expanding.

~150 DEG C are passed through air and are sufficiently stirred to obtain asphalt, improve stirring container temperature to 180~190 DEG C, SBS is changed
Property agent and initiator are slowly added into asphalt and are sufficiently stirred to obtain modified pitch material, cool the temperature to 120~140 DEG C
Afterwards, then successively mineral filler, fiberfill, softening agent, tackifier and age resister are added into modified pitch material, is sufficiently stirred
Obtain coating raw material；
(2) it prepares coating: coating raw material being transferred to high-shear impeller and temperature is increased to 205~220 DEG C is stirred,
Coating raw material after stirring enters high-shear colloid mill and is refined, and the coating material temperature after refinement passes through pressure after dropping to room temperature
Prolong machine and is rolled into wide 30~80mm, the coating of 4~7mm of thickness；
(3) it prepares adhesion coating raw material: bitumen being heated to melt and stir in stirring container, is sequentially added in whipping process
Tackifier, softening agent and adhesive, be gradually decreased to room temperature and continue stir 0.5h obtain adhesion coating raw material；
(4) it prepares road maintenance material: adhesion coating raw material being coated uniformly in the one side of coating, then separation layer is covered on adhesion coating
Surface obtains road maintenance material.
6. a kind of preparation method of concrete road conserving material according to claim 5, it is characterised in that: step (1)
In, the speed of agitator being sufficiently stirred is 60~90r/min, and mixing time is 0.5~1h.
7. a kind of preparation method of concrete road conserving material according to claim 5, it is characterised in that: step (1)
In, the rate that is passed through for being passed through air is 15~20L/min, and being passed through the time is 10~15min.
8. a kind of preparation method of concrete road conserving material according to claim 5, it is characterised in that: step (2)
In, the speed of agitator of high-shear impeller is 180~300r/min, and mixing time is 10~15min；High-shear colloid mill refinement
The fineness of coating raw material is 1~10 μm.
9. a kind of preparation method of concrete road conserving material according to claim 5, it is characterised in that: step (4)
In, the coated weight of adhesion coating raw material is 50~100g/m2。
10. a kind of application of the concrete road conserving material as described in Claims 1 to 4 is any, it is characterised in that: described to answer
Method is as follows:
(1) it clears up: the sundries in blowout crack, and road cleaning around crack is clean, keep dry around crack and crack；
(2) it pastes: tearing concrete road conserving material off separation layer, adhesion coating is steadily adhered at crack downwards, guarantees coagulation
Dirt road road conserving material is adhered to the distance on the every dypass face in crack not less than 10mm；
(3) it covers: pressing to the concrete road conserving material pasted, pressure pressure is greater than 100kg and presses 5s up to Shaoshi, applies
Pressure pressure is less than or equal to the 15s that then at least presses when 100kg.
