Accompanying drawing explanation
Fig. 1 is road structure figure.
Detailed description of the invention
Below in conjunction with the accompanying drawings technical scheme is further described, but is not limited thereto, every to this
Inventive technique scheme is modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should contain
In protection scope of the present invention.
Detailed description of the invention one: present embodiments provide for a kind of being applicable to the rubber asphalt concrete that monolayer is mated formation, tool
Body includes herein below:
One, main research:
The highly anti-fatigue that had by innovation and the new material of material, the speciality of high non-deformability, tied at road
Carry out in structure system courageously from innovation, it is adaptable to monolayer is mated formation and Pavement Performance meets safely wanting of intensity and temperature stability
Ask.
Two, crucial thinking:
Rubber asphalt is Colophonium, rubber powder of waste tire and the mixture of some additive composition, and wherein rubber powder content is not
Less than 15%, and in heated bitumen, produce the expansion of rubber powder granule.The advantage of rubber asphalt is:
(1) low-temperature resistance cracking.Owing to rubber asphalt cold snap-back performance is good, glutinous good toughness, road surface cold cracking can be resisted,
Especially in cold area in north, reflection crack during for reducing pavement cracking or keeping in repair old road, highly effective.
(2) high-temperature stability is good.Road surface during high temperature can be solved and produce the rheological phenomena such as rut, washboard.
(3) ageing resistace is good.Insensitive to the ultraviolet in sunlight.
(4) resisting fatigue, abrasion performance.
Evaluation to rubber asphalt performance: we use following index: 1) ball in-degree and resilience: mainly investigate rubber drip
Blue or green performance in screening seal coat.2) flow valuve: the viscosity of main reflection rubber asphalt and high-temperature stability.3) pressure is extensive
Multiple: the ability of main reflection rubber asphalt opposing stress deformation.When pressure recovery numerical value is relatively low, the formation of rubber asphalt state is described
Not thorough, concrete reason is probably the result of the combined factors effects such as temperature, dosage, machinery.
Three, proportioning raw materials:
With rubber asphalt as cementing material, its mass content is 5～40%, and mineral aggregate uses gap grading, Gradation Control point
For 4.75mm and 0.075mm, the two filling proportion is 60～90:10～40, and the allowable error of control point 4.75mm percent of pass is
± 2% (absolute value)；The allowable error of 0.075mm percent of pass is ± 1% (absolute value).Described rubber asphalt be matrix pitch,
Rubber powder of waste tire and the mixture of additive composition, wherein: rubber powder of waste tire mass content is 15～30%, add
Agent mass content is 2.5～10%, and remaining is matrix pitch.
Four, paving process: emphasis of mating formation is rolling the control of aspect, rolls temperature and depends on the viscosity of rubber asphalt is logical
Often viscosity is the biggest, rolls temperature the highest.The first pressing temperature of rubber asphalt is typically not less than 155 DEG C, again pressure temperature the most preferably less than 135
DEG C, final pressure temperature the most preferably less than 150 DEG C.First pressing uses pneumatic-tired rollers, and vibrated roller carries out multiple pressure, and double smooth-wheeled rollers are eventually
Till being depressed into without obvious wheelmark.
Five, the theoretical basis that monolayer is mated formation:
1) plain asphalt does not has pressure to recover and rebound value, and rubber asphalt bond material shows good at normal temperatures
Elastic performance will improve the elastic performance of rubber-asphalt mixture, contributes to bituminous paving resisting fatigue and absorbs reflection crack ability
Raising.The anti-fatigue performance of rubber-asphalt mixture, can pass through making test section on true road surface, pass through carload
Under actual effect be evaluated.2006, at Harbin City Dong Hulu, (welcome district, development zone, for Airport Expwy road for we
The arterial highway in region, north side) construction rubber-asphalt mixture monolayer mats formation experimental road, and this engineering design starting point is Qin Linglu, terminal
For Kun Lunlu, total length 487.2 meters, road is double width transverse section type, and every width car lane is wide 12 meters.This section is by airport, Harbin
Road near zone enters one of belt entrance at a high speed, and many heavy-duty vehicles pass through, and overloaded vehicle is more, and road load is overweight,
Before making, generally there are the phenomenons such as check crack, depression, frost boiling in road surface, and collapse state ratio is more serious, it is impossible to meets and is open to traffic normally
Requirement.Development zone, Harbin municipal administration relevant departments, through certification repeatedly and the consideration to current market situation, finally determine making rubber
Glue asphalt, road structure figure as it is shown in figure 1, high temperature performance test index as shown in Table 1 and Table 2.
Table 1 high temperature stability performance index
Table 2 low-temperature stabilization performance index
2015 (after 9 years), road conditions tune difference time situation is:
Pavement damage ratio (DR): 10.7；
Pavement distress (PCI): 60.2；
Road surface breakage opinion rating: in.
From data above it will be seen that Rubber-Asphalt Pavement in actual applications, road structural system is (logical by threeply degree
It is often 6+5+4cm), it is thinned to monolayer 6cm, in the case of the thinning half of thickness, the pavement investigation result after 9 years shows: road
Situation outclass common dense bitumen compound.Increase, the increase of cementitious matter consumption and rubber due to rubber asphalt viscosity
The increase of asphalt film thickness and the elastic performance of rubber asphalt, thus impart the fatigue resistance that rubber-asphalt mixture is high
Energy.Thus having established rubber-asphalt mixture can be with thinning road surface thickness, it is adaptable to the great potential that monolayer is mated formation.
2) rubber asphalt has higher dynamic shear rheological G*/sin θ value and rubber asphalt softens point value, during high temperature relatively
Plain asphalt is hard, and feature soft compared with plain asphalt during low temperature imparts rubber-asphalt mixture and has splendid non-deformability.
