Description
Technical field
The present invention relates to building engineering field, a kind of noise road surface and its construction method are referred in particular to.
Background technology
In order to research and develop the more tire with muting function, the macrovoid that fit exploitation is tested about muting function is made an uproar
Sound test pavement, with reference to the decibel value spectrum curve in 0~500HZ of international standard, the decibel value needs of stage casing 260HZ are energized into
Close to 60 range, whole decibel spectrum curve meets 80% or more similarity (± 3dB), passes through testing inspection, conventional proportions
Bituminous paving cannot reach requirement.And it has the following defects：Though 1. hot asphalt blended stock in transportational process using one
Fixed heat preservation covering methods, but still have a degree of temperature loss, the temperature of mixture at special transport vehicle surface 20cm；And
Macrovoid noise test road asphalt construction technology takes longer, and temperature declines very fast, construction technology when mixture construction
Time is compacter, and temperature holding is affected by factors such as temperature, construction times, and quality control difficulty is big；2. because pitch mixes
Material grading is matched for single-stage, and structural strength and stability are relatively low, and the case where pellet peeling occurs in when test；3. after the roller-compaction of road surface
Distribution of pores is uneven, and porosity (i.e. construction depth examination criteria) cannot be met the requirements, so road surface tire noise excites
Decibel value cannot meet spectrum requirement.It is therefore necessary to be laid with a kind of noise road surface meeting automobile tire standard noise test.

Step 11：Mixture is mixed by proportioning as described in claim 1；
Step 12：Mixture is stirred evenly, mixing time 4min；
Step 13：Haul；
Step 14：It paves：Hot iron is not added with to put down and roll leveling；
Step 15：Plastic film coated protection.
Further improvement of the present invention is that the time of the construction method is less than or equal to 3 hours.
Further improvement of the present invention is that step 12 uses forced stirrer, the forced stirrer to mix cylinder use
Drum-type, and the madial wall welding mixing page for mixing cylinder.
Further improvement of the present invention is that step 14 is paved using crawler-type paver.
Further improvement of the present invention is, is not heated using screed in step 14 and carries out the ironing that paves, and in institute
It states and improves setting roller on paver to carry out rolling leveling.
Further improvement of the present invention is, after step 14, is rolled using road roller, and the road roller includes
Steel road roller and nine takes turns pneumatic-tired rollers after preceding glue, and steel road roller road pavement back and forth rolls twice after the preceding glue, and first pass is quiet
Pressure, second time plus hammer ram vibrations；The nine wheels pneumatic-tired rollers back and forth roll 5 times.
Compared with prior art, the beneficial effects of the invention are as follows：
High adhered modification pitch is replaced to carry out production and construction, new material using new material RA retinasphals (cold mixing material)
RA retinasphals have stronger caking property than high adhered modification pitch, while being adjusted to pitch blended stock grading, control material
Dosage, and the time of stirring and uniformity, it is more reasonable by designing to meet pitch blended stock structural strength and stability
Mixture Ratio and permutation and combination go out and most preferably roll mode, reach road surface porosity and meet design requirement, make tire noise
Test frequency spectrum, which meets, need to reach testing requirement.
Description of the drawings：
Fig. 1 is the structure chart on the noise road surface of the present invention；
Fig. 2 is the excitation schematic diagram on the noise road surface of the present invention.
Specific implementation mode：
With reference to specific embodiment, the present invention is described in detail.
The present invention provides a kind of noise road surface, the pitch batch matched using single-stage, including two kinds, one is middle grain formulas
The proportioning of asphalt (AC20), asphalt is RA retinasphal ratios：3.0%~4.5；The building stones of grain size 18-22
Ratio：80.0%~85.0%；The building stones ratio of grain size 8-12：10.0%~15.0%；Cement proportion：4.0%~5.0%；
Another is particulate formula asphalt (AC16), and proportioning is：RA retinasphal ratios：3.0%~4.5%；Grain size 14-
17 building stones ratio：80.0%~85.0%；The building stones ratio of grain size 3-5：10.0%~15.0%；Cement proportion：4.0%~
5.0%.The density of the asphalt eventually formed is 2.5~3.0g/cm3.Both road surfaces AC20 and AC16 are spaced and parallel
Arrangement, totally 4 width road surface, every width width of roadway are 1 meter.And AC20 construction depths require to be 10 ± 2mm；AC16 construction depths are wanted
It asks as 5 ± 2mm.
The present invention also provides a kind of construction method on noise road surface, by RA retinasphals, building stones and cement according to than
Example is mixed, and using forced stirrer, is mixed cylinder and is used drum-type, and cylinder madial wall welding mixing page is mixed, and purpose allows pitch to mix
Material mixes and stirs more uniformly.Mixing time control is 4min, and while guarantee mixture does not bond and mixes cylinder, building stones are dripped with RA resins
Blueness can be sufficiently mixed uniformly, and retinasphal is made adequately to wrap up building stones.Then material transport equipment uses loading machine, convenience in transport to unload
Material, avoids causing secondary pollution.
Then it paves, using crawler-type paver；
Levelling mode：Computer Automatic Levelling bar is located on the 5m aluminium alloy rulers that absolute altitude is controlled；
Evenness of road surface measure：Screed presses, and does not heat, and prevents RA retinasphals from bonding, and increases roller after paver, profit
Leveling is rolled with roller gravity；
Stirring cage state：When the stopping time turn, mixture at stirring cage 1/2, prevent cold mixing RA retinasphals isolate.
Preferably, carrying out hand finish before rolling, it is primary that small range trimming is observed again after rolling for the first time.
After the completion of paving, rolled back and forth 2 times (rubber tire is preceding) using steel road roller after preceding glue, first pass static pressure, second
Add hammer ram to shake all over road roller, is then rolled back and forth 5 times using nine wheel pneumatic-tired rollers, finally use the small road roller of steel after preceding glue
1 time (rubber tire is preceding) is rolled, plans that reasonable length is one and rolls section according to field condition.After the completion of rolling, carries out covering and support
Shield.
Because the factors such as transport, construction time, temperature are affected to mixture temperature, RA trees under room temperature are controlled
Construction was completed before the fat asphalt presetting period (3 hours), avoided shadow of the hot-mix asphalt mixture temperature to construction quality
It rings.
The present invention carries out production instead of high adhered modification pitch by using new material RA retinasphals (cold mixing material) and applies
Work, new material RA retinasphals have stronger caking property than high adhered modification pitch, while being adjusted to pitch blended stock grading
It is whole, material utilization amount, and the time of stirring and uniformity are controlled, to meet pitch blended stock structural strength and stability, is led to
It crosses design more reasonably Mixture Ratio and permutation and combination to go out and most preferably roll mode, reaches road surface porosity and meet to design and want
It asks, testing requirement need to be reached by so that tire noise test frequency spectrum is met.
The foregoing is merely the preferred embodiment of the present invention, not thereby limit the scope of patent protection of the present invention, all
It is directly or indirectly to be used in other relevant technologies with equivalent structure transformation made by description of the invention and accompanying drawing content
Field includes similarly within the scope of the present invention.
