Description
Technical field
The invention belongs to building material technical field used in road engineering, and in particular to a kind of draining regeneration asphalt is mixed
Close material and its proportion design method.
Background technology
Drainage asphalt pavement is a kind of typical skeleton-pore structure, and substantial amounts of connectivity gap is internally formed hair in road
The drainage network road for reaching, rainwater is discharged along road horizontal wall inscription by net road by portion in the body of road, because it has excellent antiskid performance, table
The face not function such as ponding and absorbing sound and lowering noise, is subject to more and more extensive popularization and application in the build of bituminous paving upper layer, but
Because China's bituminous pavement design life-span is 10-15, therefore, drainage asphalt pavement will enter the medium-capital overhauling stage how
It is the urgent task for facing at present to process these discarded drainage asphalt mixtures.
Due to gathering materials using expensive high-viscosity modified asphalt and high-quality more than drainage asphalt mixture, in maintenance process
In directly its milling is abandoned or can not only trigger environmental pollution for road surface cutting optimal as reclaimed materials, while can also cause
A kind of huge economic loss.Therefore the regeneration issues of research drainage asphalt pavement are just particularly important.
Current regeneration techniques just for matrix pitch and common hot-mix asphalt mixture, for Modified Bitumen Pavement
Study of Regeneration Technique is less, and the regeneration techniques and drainage asphalt pavement regeneration techniques that are directed to high viscosity modified pitch are even more one
Piece blank.
At present, drainage asphalt pavement has been flourished at home as a kind of novel pavement, but in view of drip
The blue or green pavement life time limit, the regeneration techniques supporting with it is not yet effectively solved.
The content of the invention

Draining reclaimed asphalt mixture, it is characterised in that：Including reclaimed materials, gather materials, filler, fiber stabilizer and dilution drip
It is blue or green.
Further, the reclaimed materials be drainage index by after the pavement usage in more than ten years again by digging,
Milling and come；Described to gather materials including coarse aggregate and fine aggregate, the coarse aggregate is basalt, and the fine aggregate is limestone；
The nominal maximum aggregate size for gathering materials is 13.2mm；Described filler is limestone dust；The fiber stabilizer is fine lignin
The composite fibre of dimension or basalt mineral fiber or both, volume be the draining reclaimed asphalt mixture quality 0.1%~
0.6%；The cut-back asphalt is diluted polymer modified pitch, and volume is the draining reclaimed asphalt mixture quality
4.8%~7.6%.
Further, the diluted polymer modified pitch includes matrix pitch, modifying agent, wax, diluent and antistripping
Agent, wherein：The matrix pitch is 70# matrix pitches；The modifying agent is asphalt modifier with high viscosity, and addition is described dilute
Release the 8%~12% of polymer modified asphalt quality；
The diluent is diesel oil or kerosene, addition be the diluted polymer modified pitch quality 16.9%~
21.6%.；The antistripping agent is a kind of surfactant for increasing pitch and building stones adhesiveness, and addition is poly- for the dilution
The 2%~6% of polymer modified asphalt quality.
Still further preferably, the antistripping agent is the surfactant of aminated compounds or phosphorus hydroxyl organic matter.
In order to realize above-mentioned technology improving eyesight, another technical scheme that the present invention takes is：
A kind of proportion design method of draining reclaimed asphalt mixture for above-mentioned draining reclaimed asphalt mixture, it is special
Levy is to comprise the following steps：It is foundation to use interference theory, and control coarse aggregate is with fine aggregate key sieve size by hundred
Divide rate proportionate relationship.
Further, described reclaimed materials, gather materials with filler entirety grading limit it is as follows：
Further, by controlling coarse aggregate with fine aggregate key sieve size by percentage proportionate relationship, thickness
The division gathered materials be use interference theory be design theoretical foundation；When three mutual embedded squeezings of ball, contact surface is respectively sphere
Or during plane, there is four kinds of possible combinations, the space for being formed is respectively 0.15,0.20,0.24 and 0.29 times of circular diameter, is taken
Its average value, using 0.22 times of corresponding screen size of nominal maximum aggregate size size (D) as thickness in compound gather materials point
Boundary's point, is coarse aggregate more than gathering materials for separation, is fine aggregate less than gathering materials for separation.
The present invention first uses Grey Theory Analysis reclaimed materials influence factor, is ensureing drainage index pavement performance
Optimize the mixture proportion of reclaimed materials simultaneously.
