With being to make upper and lower bitumen layer or bitumen layer and structure to be bonded to an entirety completely, promote layer and layer it
Between formed entirety force structure, thus reduce caused by traffic loading interlayer structure dislocation and sidesway, subtract
The generation of few pavement disease, improves pavement durability.
But, in Practical Project is constructed, cause a major reason of interlaminar bonding poor effect to be,
Existing adhesion coating emulsified asphalt is after spread, though breakdown of emulsion film forming completely, the most usually by Construction traffic
Wheel roll after take away, cause the loss of bonding layer material, reduce bond effect, glue the emulsifying walked simultaneously
Surrounding enviroment are also polluted by Colophonium.It addition, the existing adhesion coating emulsified asphalt breakdown of emulsion time is long, dispensing
After, unit in charge of construction would generally wait a few hours, and the vehicle that could allow to pave is marched into the arena and carried out paving of compound,
Efficiency of construction is caused to reduce.
The Chinese patent of Publication No. CN104448848A refer to the preparation of a kind of adhesion coating emulsified asphalt, its
Fast solidifying, the effect of not viscous wheel can also be reached.Colophonium used is matrix pitch, however it is necessary that and adds in Colophonium
Enter Interface enhancer such as polyethylene or polyacrylic polymer, make enhancing modified Colophonium, preparation process need by
Colophonium is heated to 160 DEG C-170 DEG C, then carries out emulsifying and prepares emulsified asphalt.
Summary of the invention
Take turns for easy to stick existing for above-mentioned existing adhesion coating emulsified asphalt, cohesive force insufficient strength, and breakdown of emulsion
The technological deficiencies such as speed is slow and causes efficiency of construction is low are asked, an object of the present invention is to provide one not
The viscous or not wheel emulsified asphalt taking turns, coagulate soon, improve adhesion strength.
The two of the purpose of the present invention are to provide a kind of preparation method for preparing above-mentioned emulsified asphalt.
The three of the purpose of the present invention are to provide the application technology scheme of a kind of above-mentioned emulsified asphalt.
In order to achieve the above object, the present invention adopts the following technical scheme that:
The not viscous wheel emulsified asphalt of one, the following ingredients including accounting for its gross mass percentage ratio: 10%-50% base
Matter Colophonium, 10%-50% hard grades of bitumen, 0-5% polymer modifiers, 0.3%-3% asphalt emulsifier, 0-1%
