Functional relation, but permitted by asphalt characteristic, construction temperature, compacting equipment combination, debulking methods and compacting counting etc.
Multifactor impact, and a kind of mathematical relationship presented with statistical rule.Therefore it during Construction of Asphalt Pavement, is only capable of to pressure
Real thickness carries out rough control, it is difficult to strictly control compacted thickness in exact extension completely.
The passage effect of road roller：Road roller is mixed with pitch due to rolling wheel surface in moving forward or back roller compaction process
Closing material, there are larger horizontal friction forces, therefore can push asphalt and occur laterally in wavy along road roller travel direction
It is mobile, interim well lid or permanent well seat in the case that it is unlocked firmly can be by being conducted through the horizontal load come by asphalt
Lotus is subjected to displacement or deforms.The effect control is not in place to easily cause the poor problem of flatness around inspection shaft.
Around inspection shaft asphalt surface course because of the fixation of well lid absolute altitude in roller compaction process and asphalt thickness dynamic and
Uncertain variation and the problems such as cause the local protuberance of well week asphalt surface course, pit.Since such problem is in work progress
Road roller, asphalt and the triangular dynamic response of well seat are directly contributed and are directly shown after the completion of constructing flat
Whole degree problem, referred to as " initial flatness problem ".
Well week, loose, cracking occurred for asphalt surface course and sedimentation can reduce the smooth of asphalt surface course around well during operation
Degree, influences vehicle pass-through quality, vehicle is jumped when vehicle being caused to cross.Such problem be since well week asphalt surface course compactness is insufficient or
Differential settlement caused by the compactnesss deficiency such as base, roadbed within the scope of person's well week, and gradually develop in the operation phase, cause well all
Out-of-flatness and jump vehicle phenomenon, referred to as " later stage flatness problem ".
Generally use of constructing around inspection shaft asphalt surface course at present blocks inspection well head with transition cover board, then successively paves
Asphalt surface course, then will check that the pitch near well head is cut off, it is foundation installation check well well seat and well lid with asphalt surface course absolute altitude,
Last Manual asphalt, by the method for the vacancy polishing around well seat.
Existing method has the following defects：
1. the asphalt surface course around inspection shaft is cut off together after the completion of two layers of Mian Ceng makings.Installation is complete for well seat
Afterwards, the vacancy of surrounding is successively repaired using artificial distributing mode and is rolled.Since inspection shaft well coordinate height is higher than pitch cutting optimal, because
Armpit angular position road roller can not roll in place around well seat when this pitch cutting optimal is constructed, and cause pitch cutting optimal compactness at this
Deficiency is led to the problem of " later stage flatness ".
2. since excision position range is smaller, it is only capable of rolling using baby roller.It is light to roll equipment tonnage, and rolling wheel
Part is rolled across seam on molded asphalt uplayer, is rolled useful load and is further declined, and compactness deficiency is equally easily caused,
It leads to the problem of " later stage flatness ".
3. same because excision position range is smaller, in roller compaction process when seam rolls a rolling wheel part be pressed in it is rigid
On molded asphalt uplayer, another part is pressed on hot-mix asphalt mixture flexible, and rolling wheel can be past soft under gravity
Property asphalt on tilt, form local pit, lead to the problem of " initial flatness ".
4. artificial cloth is difficult to control total dosage, uniformity coefficient and the spreading evenness of bituminous mixture laying, it is easy shadow
The flatness to asphalt surface course around well seat is rung, is led to the problem of " initial flatness ".
5. molded asphalt surface course excision needs to remove using milling machine milling, mechanical one-shift is costly.
Well week the asphalt pushing phenomenon and well that are generated in road roller roller compaction process when 6. well seat fixes insecure
Seat interaction, easily leads to asphalt local accumulation, to generate protrusion or pit.
