Description
Technical field
The invention belongs to field of material technology, are related to a kind of mastic-broken stone mixture.
Background technique
The bitumastic being made of the miberal powder of asphalt binder and a small amount of fiber stabilizer, fine aggregate and more amount
It is filled in the gap of the coarse aggregate skeleton of gap grading, organizes integral asphalt, it is broken that we term it bitumastics
Stone mixture.Manufacture mastic-broken stone mixture must use fiber stabilizer, its role is to play reinforcement, dispersion, absorption,
Stable and tackifying effect, fiber have become its necessary ingredient.
Rubber asphalt is the mixture of pitch, rubber powder of waste tire and certain additives composition, and wherein rubber powder content is not
Lower than 15%, and in heated bitumen generate rubber powder granule expansion.The advantages of rubber asphalt, is:
(1) low-temperature resistance cracks.Since rubber asphalt cold snap-back performance is good, good toughness is sticked, road surface cold cracking can be resisted,
Especially in cold area in north, reflection crack when for reducing pavement cracking or repair old road is highly effective.
(2) high-temperature stability is good.It can solve road surface when high temperature and generate the rheological phenomenas such as track, washboard.
(3) anti-aging property is good.It is insensitive to the ultraviolet light in sunlight.
(4) antifatigue, abrasion performance.
Evaluation to rubber asphalt performance: we use following index: 1) ball in-degree and rebound: mainly investigation rubber drip
Performance of the blueness in screening seal coat.2) flow valuve: the viscosity and high-temperature stability of main reflection rubber asphalt.3) pressure is extensive
Multiple: main reflection rubber asphalt resists the ability of stress deformation.When pressure recovery numerical value is lower, illustrate the formation of rubber asphalt state
It is not thorough, concrete reason may be the result of the combined factors such as temperature, dosage, machinery effect.
Summary of the invention
The object of the present invention is to provide a kind of rubber asphalt Matrix mixing materials for exempting from lignin, pass through a large amount of laboratory tests
Show to produce mastic-broken stone mixture with rubber asphalt with knowhow, it completely can be in order to avoid mix cellulose.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of rubber asphalt Matrix mixing material for exempting from lignin, for by rubberized asphalt binder, fine aggregate and more
The filler (miberal powder) of amount forms and is filled in the integral mixture of dwell set of the coarse aggregate aggregate of gap grading, in which: thin
Gather materials, the mass ratio of filler (miberal powder), coarse aggregate be 10~20:15~30:60~80, the quality of rubberized asphalt binder is thick
Gather materials, the total weight of fine aggregate and filler (miberal powder) 5~15%.
In the present invention, the rubberized asphalt binder is the mixed of matrix pitch, rubber powder of waste tire and additive composition
Close object, in which: rubber powder of waste tire generates the expansion of rubber powder granule in heated bitumen, and mass content is 15~30%, adds
Adding agent mass content is 2.5~10%, remaining is matrix pitch.
In the present invention, the rubber asphalt Matrix mixing material is identical as the production equipment of other asphalts, adopts
It is produced with intermittent mixing machine.
The present invention selects rubber asphalt to replace polymer modified asphalt, and broken in same type gap grading bitumastic
In the case of stone mixture, the incorporation of lignocellulosic can be removed from, reduce production cost, while the various performances of product are all obtained into one
The improvement of step.
Specific embodiment
Further description of the technical solution of the present invention below, and however, it is not limited to this, all to the technology of the present invention
Scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical solution of the present invention, should all be covered in the present invention
Protection scope in.
Specific embodiment 1: present embodiments provide for a kind of rubber asphalt Matrix mixing material for exempting from lignin, tool
Body includes the following contents:
One, main research:
1, the suitable viscosity of rubber asphalt is determined.The essence that the viscosity index of rubber asphalt can most react rubber asphalt is special
Property, what it was measured is the resistance of rubber asphalt flowing, this resistance has indirectly reacted the quality of rubber asphalt.Rubber asphalt is viscous
Degree whether properly largely represent the superiority and inferiority of rubber asphalt performance, therefore, to produce exempt from lignin matizhi mix
Material rubber asphalt used is closed, the range of viscosities it is confirmed that suitable is first had to.
2, compare the rubber asphalt Matrix mixing material for exempting from lignin and stone mastic asphalt high-temperature behavior,
Gap in terms of cryogenic property and water stabilizing, and accordingly come measure exempt from lignin rubber asphalt Matrix mixing material it is excellent
It is bad.
Two, key technology:
1, suitable rubber asphalt viscosity.The volume of shoddy is higher in rubber asphalt, and viscosity can be bigger.A large number of experiments
When showing that rubber powder volume is under 15%, rubber asphalt viscosity build rate is low.When more than 15%, rubber asphalt viscosity build becomes faster.
But when volume is more than 30%, the increase of viscosity is made troubles to the processing and construction of rubber asphalt, therefore rubber powder content limits
Between 15~30%, meanwhile, viscosity index is limited to 20~40d.Pa.s.A large number of experiments show that volume and viscosity at this time
Range is the optimum condition range for exempting from lignin fibre rubber asphalt Matrix mixing material.
2, raw material proportioning: fine aggregate, filler (miberal powder), coarse aggregate mass ratio be 10~20:15~30:60~80, rubber
The quality of glue asphalt binder is the 5~15% of the total weight of coarse aggregate, fine aggregate and filler (miberal powder).The rubber asphalt knot
Close the mixture that material is matrix pitch, rubber powder of waste tire and additive composition, in which: rubber powder of waste tire mass content
It is 15~30%, additive mass content is 2.5~10%, remaining is matrix pitch.
3, the identical gap gradation of stone mastic asphalt is taken, the rubber-asphalt mixture performance system of lignin is exempted from
It counts as follows:
It can be seen that each performance that this rubber asphalt Matrix mixing material for exempting from lignin is showed is very excellent
It is different.The Xuanhua of Harbin in 2011 bridge pioneer crossing section is laid with this rubber asphalt Matrix mixing material for exempting from lignin, so far also not
Generate any road disease.
Specific embodiment 2: the present embodiment is different from the first embodiment in that: fine aggregate, filler (miberal powder),
The mass ratio of coarse aggregate is 12:16:65, and the quality of rubberized asphalt binder is the total of coarse aggregate, fine aggregate and filler (miberal powder)
The 8% of weight.
Specific embodiment 3: present embodiment is unlike specific embodiment one, two: fine aggregate, filler (mine
Powder), the mass ratio of coarse aggregate be 15:20:70, the quality of rubberized asphalt binder is coarse aggregate, fine aggregate and filler (miberal powder)
Total weight 10%.
Specific embodiment 4: present embodiment is unlike specific embodiment one, two, three: fine aggregate, filler
The mass ratio of (miberal powder), coarse aggregate is 18:25:75, and the quality of rubberized asphalt binder is coarse aggregate, fine aggregate and filler (mine
Powder) total weight 12%.
Specific embodiment 5: present embodiment is unlike specific embodiment one~tetra-: rubber powder of waste tire
Mass content is 18%, and additive mass content is 4%.
Specific embodiment 6: present embodiment is unlike specific embodiment one~five: rubber powder of waste tire
Mass content is 22%, and additive mass content is 6%.
Specific embodiment 7: present embodiment is unlike specific embodiment one~six: rubber powder of waste tire
Mass content is 28%, and additive mass content is 8%.
