Bituminous paving of the present invention oozes the maintenance construction method of solid wearing course substantially as shown in Fig. 2, comprising the following steps：
Step 1）Solid agent spread quantity is oozed to survey：
By being made an on-the-spot survey to former road surface, choose most representational section and carry out coring sampling, core sample is uniformly cut into surface
2cm, using trichloro ethylene be stripped recycling after heating indoors, the detection that pitch carries out needle penetration, ductility, general will be recycled
Testing result and new pitch index（The claimed range lower limit of same index in i.e. existing Asphalt Pavement Construction Technique specification）Carry out
Compare and calculate attenuation ratio, as the preliminary foundation for determining to ooze solid component spread quantity.Attenuation ratio is big, illustrates that aging is serious,
The spread quantity needed is with regard to big.When there is one to be more than 20% in the attenuation ratio of needle penetration or ductility, it should ensure that every square metre oozes admittedly
The spread quantity of agent is no less than 0.3Kg；When there is one to be more than 50% in the attenuation ratio of needle penetration or ductility, every square should ensure that
The spread quantity that rice oozes solid agent is no less than 0.5Kg.With reference to indoor degradation as a result, carrying out simulation coating examination at construction section scene
30 minutes absorptivities, the direct basis as site operation spread quantity are determined in test.
Step 2）Clean road surface：

Ensure on former road surface without ponding.
Step 3）Road surface pre-processes：
Former road surface must have the structural strength of abundance.Former road surface partial structurtes intensity deficiency, it is necessary to select as the case may be
Suitable method carries out reinforcement.When the track of former below road surface 10mm can directly carry out maintenance processing, the car more than more than 10mm
Rut position, carries out track and fills up in advance as the case may be.At the same time in order to avoid hidden danger, the prior fracture cementation of fissures and repairing road are answered
The diseases such as table pit slot, depression are repaired.
Step 4）Solid agent is oozed in sprinkling：
Solid agent finished product will be oozed to load in intelligent distribution vehicle or rubble synchronization distribution vehicle, intelligence is demarcated according to the spread quantity calculated in advance
Distribution vehicle, implements the spread operation on former road surface（Spread quantity scope 0.3-07kg/ ㎡）, treat 20-30 minutes, ooze solid agent and fully ooze down
It is allowed for access after reaction lower road working procedure.Oozing the solid agent absorbed time can be influenced by weather, sun-drenched in fine day
In the case of, speed, if the cloudy day, the time can extend, and extend conditioned time to 40-60 minutes.
Step 5）Pave wearing course：Asphalt wearing layer is prepared by four raw materials and proportioning is implemented
It is required that using automatic slurry seal paver, it is divided into the following steps：
1）Laying-down：According to lane width, paving box width is adjusted, it is integer to make construction range of driving number.Width is from road accordingly
Edge starts setting-out, and general first car marks strike angle line since the left side.
2）Charging：Satisfactory high molecular polymer is modified high-viscous emulsified asphalt, filler, basalt, water, silicate
Cement etc. is respectively charged into the corresponding hopper of paver.
3）Pave
A. charged paver is opened to construction starting point, is directed at strike angle line, spreader is placed on operating position, and adjust
Paving box thickness and camber, offset plate is turned-out after spreader, its excess-three side offset plate is to varus, adjustment slideway height, camber adjustment
Screw, is allowed to the paving thickness for meeting construction requirement, holding makes paving box periphery be adjacent to former road surface, and hangs up properly mop；
B. machine after confirming the height or aperture of each bin gate, cylinder clutch is mixed and stirred in engagement, agitating shaft is run well, and open
Open paving box spiral distributor；
C. each bin gate controlling switch is opened, enters high molecular polymer modification high-viscous emulsified asphalt, filler, basalt, water and mixes
And cylinder, and when the mixture prewetted is elapsed to lotion ejiction opening, lotion sprays；When wherein stirring, by controlling switch into one
Step fine setting water, makes asphalt denseness moderate, is advisable with that can pave but not trickle（It is when surface humidity is higher, it is necessary to few
Add water, or even be not added with water）；
D. adjust mixture dividing to the flow direction on device, mixture is equably flowed to paving box or so；
E. when mixture is evenly distributed in the range of the overall with of paving box, start chassis, and slowly move ahead, but should the temperature remains within the normal range
Bituminous mixture laying amount and output are basically identical, keep the volume of mixture in paving box as 1/2 left side of paving box volume
It is right.Pay special attention to prevent from overflowing in construction；
F. all switches should be closed immediately when any type material is finished on paver, the mixture allowed in a mixing bowl stirs
Uniformly, and it is sent into after paving box paved, that is, stops moving ahead；
G. material is added when paving again, is paved since previous car terminal retreated at 3-4m, front and rear sealing twice is had one section of weight
It is folded.Raised and excessively dilute mixture is struck off, the oil-water ratio that avoids just start shooting be not allowed caused by come off, make to connect stubble and smooth out neatly；
H. paving box is lifted at the end of constructing, then by paver together with paving box Kai Zhi roads outside, cleaning and paves at a mixing bowl
Case.
4）Joint treatment
A. transverse joint is handled：Generally transverse seam is made the form of butt-welded side seam, and automatic slurry seal paver is in starting point
When, slightly slowly advance, so can be to avoid making to pave blocked up because the mixture in paving box is excessive, the arch camber of generation shows
As.After a car has been spread, with the neat connector of spade, one block of iron sheet is spread in joint, concordant with connector end, paver vehicle plays stand
Paving case falls to stop in joint, and paving box is put on iron sheet, after paver advances, by iron sheet together with mixture thereon
Together take away.
B. longitudinal seam is handled：
Gradually construct by by outer lateral median strip in construction track（From low to high）, during construction, should first be connect in making half range
Water process of prewetting is carried out at seam, paving box edge infinite approach has spread track edge, and slurry mixture has necessarily oneself in itself
Trickling, is conducive to the linking of two track mixtures.In case of overlapped place that is blocked up or not connecting, should manually strike off before the forming.
Step 6) manual amendment：
After mixture laying, manually levelling, including starting point, terminal, longitudinal seam should be carried out immediately, blocked up, excessively thin or uneven place,
The scratch especially produced to super large particle diameter mineral aggregate, should remove and fill and lead up as early as possible.
Step 7) initial curing：
After oozing solid wearing course mixture making, forbid all vehicles and pedestrians before open to traffic.Mixture laying is latter
As be not required road roller roll.For hardened verge, parking lot when lacking either occasion without traffic bound or in order to
Meet some special requirements, 6-10t pneumatic-tired rollers can be used to being demulsified and preliminary molding mixture rolls.Can
Meeting after the requirement of open to traffic should open to traffic as early as possible.
Closing and open to traffic：
Before this method construction, pass blocked road is generally required, closes traffic.
After initial curing, oozing solid wearing course and still needing to time of one section of health after initial set is reached just can gradually harden to and can prop up
The degree that vehicle rolls is held, thus the time of open to traffic should be more longer than presetting period, vehicle should be forbidden within this period
It is current, in order to avoid leave the trace of wheel.The time of open to traffic will determine according to situations such as scene temperature, wind speed.
