4. between the soil layer and macadam of bases, be provided with substrate filtering material layer, the thickness of described substrate filtering material layer is 0.05 ~ 0.15mm;
5. machine spreading: during drainage topping on pave, namely pave many spaces dewatering and noise reduction bituminous mixture time, paver adopts the conventional sliding equalizer bar of truss;
6. joint treatment: adopt the direct joint-cutting of electric pick, then blow dust with air compressor machine or forest fire extinguisher, then rinse seaming position with water, prevent the blocking of connectivity gap;
7. maintenance of surface: adopt vacuum draw or high pressure water flushing to inject row periodic maintenance.
Step 1. in, the absolute viscosity of described modified asphalt mixture is more than or equal to 20,000PaS under 60 DEG C of conditions.
Long-life recited above, penetrating induction type drainage pavement comprised penetrated asphalt pavement, permeable concrete road surface and porous brick.
Embodiment 2: the Specific construction step of penetrating induction type drainage pavement of a kind of long-life is as follows:
1. mix-design: the production mix proportion of Experiment Road carries out on job laboratory.First carried out Indexs measure to the raw material in hot storehouse, then carried out Marshall Test according to correlation step, finally determining that hot storehouse thickness is gathered materials with the ratio of modified asphalt mixture is: 58.5:35.85:5.65
2. process is mixed and stirred:
Before asphalt plants mixes and stirs, batching plant grating, bitumen aggregate ratio are carried out examination and adjusted, grating is made to be tending towards the intermediate value of grading limit, lorry mounted mixer is equipped with pneumatic conveyer, add fiber, asphalt heating temperature controls be no more than 180 DEG C, mineral heating up temperature 190 ~ 2lO DEG C, bituminous mixture dispatches from the factory normal 180 ~ 185 DEG C, and in bin stock process, temperature reduction is no more than 10 DEG C.
For mixing and stirring of composite modified fiber compound, what can refer to common SMA mixture mixes and stirs process.First by fiber and gathering materials and breeze dry mixing certain hour, then spray into pitch and mix and stir.
Mixing and stirring for modified fibre, because fiber wherein adds the cause of modifier, when temperature reaches more than 180 DEG C, fiber and modifier are become by dispersity and cohere block, join pole among gathering materials and be difficult to dispersion, therefore need in practice of construction, modified fibre and pitch are sprayed into batching plant simultaneously, and actual effect display effectively can avoid the generation of the problems referred to above; The blending technics of composite modified fiber is identical with the technique of general fibre, adds pitch again after first carrying out dry mixing certain hour.
The bituminous mixture mixing time should all be wrapped by pitch with compound uniform mixing, all mineral aggregate particles and determine through trial mix, the time that general batch mixer mixes and stirs one pot is 55 seconds, the conjugate fiber due to admixture, increase by 10 seconds compound dry mixing time, when condition license, suitably can increase the mixing time again.The bituminous mixture that batching plant mixes and stirs answers uniformity without grey material, becomes block or serious coarse fodder segregation phenomenon without conglomeration.The compound mixed and stirred when requiring as do not reached must not use, and should search problem and adjust solution in time.
3. prepare before paving: the foreign organic matter cleaning surface before paving, and remove road surface dust with air compressor machine or forest fit-extinguishing, road surface is made to keep clean without dust, carry out the spread of SBS modified bitumen bond capacity after also evaluation and test recognized by label through management Cheng Shi passed examination, locally and in the vertical edges of milling position manually brush with brush in concrete guardrail, people's (hand) hole etc.; The abundant preheating of screed before paving, " the C or higher that reaches 100.Mixture laying temperature is not less than 170 " C.Mercurial thermometer close inspection is used at scene, guarantee that the qualified material that mixes and stirs paves, otherwise the type fiber mixture is difficult to compacting.
4. machine spreading: it is 1.2 that the coefficient that paves controls.
5. roller compaction process: because bituminous mixture cohesive strength after adding of fiber in compound increases, need increase rolling layer 2 ~ 3 times when rolling, to reach best compactness.When rolling, driving wheel is front, steppedly to roll, finally oblique 45 of multiple pressure and final pressure ", road roller must not be reversed end for end or stop-for-waiting on non-roller-compaction and uncooled section; must carry out on cold burden when adding water, generally be advisable from paver 150 ~ 200 meters.The corner that road roller cannot be pressed onto, adopts hand compaction; The road surface complete to multiple pressure is detected with 6 meters of rulers, finds that out-of-flatness place is marked, and arranges road roller to eliminate to the sags and crests that may occur.
6. joint treatment: longitudinal seam adopts cold joint, carries out channel-section steel dismounting after having rolled.Horizontal construction joint adopts flat seam, carry out when laying compound cooling but not yet hardening, detect with ruler butt joint place, to injustice, place all cuts, so that seam Shunping County, remembers the paver elevation angle simultaneously, when making seam, the elevation angle is consistent, roll and adopt that road roller is oblique rolls, and then longitudinal rolling, emphasis process is done to out-of-flatness place road roller.
Embodiment 3: adopt construction method of the present invention second day road pavement degree of compaction after construction completes to adopt boring method to detect, each section of testing result is as shown in table 6.1:
From compaction detect result, paving material is larger on the impact of the consolidation effect of compound, first should ensure that its paving material is at about 170 DEG C in the fiber mixture paving process afterwards of this two type.
Be open to traffic after half a year in the Experiment Road completion that paves, we investigate the pavement usage situation of Experiment Road, and have carried out the mensuration (construction depth > 0.55mm) of pavement seepage coefficient and pendulum value, and result is as shown in table 6.2:
Embodiment 4: the penetrating induction type drainage pavement that construction method of the present invention is laid compared with traditional prevailing roadway when not increasing investment, effectively can reduce noise, reduce water smoke, be both conducive to environmental protection, more be conducive to traffic safety, meet the trend of current technological development.Concrete function is as follows:
(1) reduce the danger of " water drift " at a high speed, make, when road table has water, still can maintain the good contact on tire and road surface.
(2) improve the visuality at rainy day and night, what rainwater produced dabble and water smoke can reduce greatly, and rainy day and driving at night reverberation can be disperseed by road structure, and dazzle is little.
(3), under high speed traveling, cling property is significantly higher than prevailing roadway.
(4), due to the mechanism of porous sound absorption and connectivity gap earth pressure release, noise is decreased significantly.
(5) the raising of the aspect such as preventing atomization, fatigue resistance, non-skid property, durability makes service life of road surface extend about one times, reach more than 10 years application life, without there being common pavement disease to occur on the road surface using construction method of the present invention, for common earth, machine oil and household garbage, there is good contamination resistance, through good maintenance, road surface is durable as new, meets the requirement of porous pavement to matsurface.
