Traffic lane line described in the present invention swings amplitude for last time swinging the side-play amount of graticule position, back relatively.
Among the present invention related compact car track and heavy goods vehicles track be meant the freeway traffic Warning Mark the clear and definite track of specializing in corresponding vehicle vehicle ' of indication.
Being suitable for the maintenance road surface of treating based on the bituminous pavement preventive maintenance method that swings traffic lane line provided by the present invention is that one side is provided with the band that stops in emergency, another side is provided with middle band; And the centre is with and is stopped in emergency and is provided with the asphalt pavement of highway in compact car track and heavy goods vehicles track between the band at least; For clearlying show the concrete steps of this method, definition brings to the band that stops in emergency along the centre direction is a positive direction, and the direction that brings to middle band of stopping in emergency is opposite direction; Said treating is provided with n track through (n+1) bar traffic lane line on the maintenance road surface; And on positive direction, be followed successively by: first lane graticule, first lane, second lane graticule, second lane, third lane graticule to the n track, (n+1) traffic lane line, n is a positive integer, and n >=2; With reference to figure 1 and Fig. 2, method is undertaken by following step:
Step 1 detects rut degree of depth RD and traffic lane line retro-reflecting coefficient RC, as RD>=10mm or RC≤80mcdlx -1M -2The Shi Jinhang step 2, otherwise this treats that the maintenance road surface temporarily do not launch technical scheme of the present invention and carry out maintenance;
What need to analyze explanation is: when rut degree of depth RD＜10mm, to not obviously influence of normal driving; When rut degree of depth RD>=10mm, the ponding in the rainy day rut causes driving vehicle to produce the neatly effect easily, jeopardizes traffic safety, and in addition, when the vehicle lane change was gone, darker rut can increase driver's controlling difficulty, reduce occupant's comfortableness vehicle; According to " road traffic marking quality requirement and detection method " (GB/T16311-2009), as traffic lane line retro-reflecting coefficient RC≤80mcdlx -1M -2The time, graticule has reached application life, and night, visibility did not satisfy the safe driving requirement; Can not guide driving at night well; Need execute again and draw, it is most economical implementing that graticule swings this moment, therefore; From travel safety, comfortableness, handling and engineering economy angle, step 1 is rut degree of depth 10mm or traffic lane line retro-reflecting coefficient 80mcdlx -1M -2Confirm as the trigger value that traffic lane line swings.

Figure BDA00002049488900061
to swing direction and is positive direction; Thereby make wheel roll a crest of rut, and then accomplish traffic lane line and swing for the first time;
Step 3 detects the traffic lane line retro-reflecting coefficient RC ' that treats the maintenance road surface that accomplishes after traffic lane line swings for the first time; As RC '≤80mcdlx -1M -2The time, (n+1) bar traffic lane line after swinging is for the first time swung respectively, wherein, the amplitude of swinging of first lane graticule does
Figure BDA00002049488900062
Swing direction in the other direction, initial relatively graticule position is 0 after swinging; The amplitude of swinging of second lane graticule does
Figure BDA00002049488900063
Swing direction in the other direction, initial relatively graticule position does after swinging The amplitude of swinging of other traffic lane lines is W, swings direction in the other direction, and initial relatively graticule position does after swinging
Figure BDA00002049488900065
And then the completion graticule second time swings;
What need the analysis explanation is:
Be generally heavy goods vehicles with the vehicle that stops in emergency with going in the adjacent track; The destruction of its road pavement is the most serious; Preferentially satisfy it and swing condition, make to swing another crest that rear wheel rolls rut, therefore; The amplitude of the swinging second time of other traffic lane lines except that first lane graticule and second lane graticule is W, swings direction in the other direction;
In addition, have only the left side marginal strip of 0.5～0.75m usually between speedway first lane graticule and the middle branch band, for guaranteeing traffic safety, this marginal strip can not compress, and the first lane graticule does not just possess the condition that swings to opposite direction like this;
And each track of speedway is wide, is 3.75m; Wherein large car car body broad, wheelspan are bigger, and the compact car car body is narrower, wheelspan is less, and correlative study both at home and abroad shows in addition: in order to guarantee normal driving; Outside Large Vehicle Lane does not possess contractive condition; Do not influence its normal driving and compress inboard Light-duty vehicle Lane width in right amount, therefore, determinedly in this step swing the traffic safety that amplitude does not influence road.
Step 4 detects the traffic lane line retro-reflecting coefficient RC ＂ that treats the maintenance road surface that accomplishes after traffic lane line swings for the second time; As RC ＂≤80mcdlx -1M -2The time, second traffic lane line to the (n+1) the bar traffic lane line after swinging is for the second time swung respectively, wherein, the amplitude of swinging of second lane graticule does
Figure BDA00002049488900071
Swinging direction is positive direction; The amplitude of swinging of other traffic lane lines does Swinging direction is positive direction; Swinging the initial relatively graticule position of all traffic lane lines of back is 0, and all traffic lane lines are kept in the center, and then accomplish swinging for the third time of traffic lane line; So far, accomplishing one of traffic lane line swings the cycle.Test shows: after swinging through twice, former wheel path rut both sides ridge rolls down to sink gradually at wheel; And former wheel path rut sink the position in both sides horizontal push effect recover gradually, at this moment, the pavement track band has been tending towards recovering smooth, therefore, swings once more and makes all traffic lane lines keep in the center;
Step 5 is judged the application life of treating the maintenance road surface; When treating that the maintenance service life of road surface does not terminate, get into the next one and swing the cycle, repeating step one is to step 4; Otherwise, finish technical scheme of the present invention this treated that the maintenance road surface carries out maintenance.
The service life of road surface termination face badly broken that shows the way adopts the routine servicing method can not make the road surface recover good working order, can not guarantee the favorable service function, need overhaul.The judgement in general road application life is a foundation with the detection evaluation result of treating maintenance road surface functional performance PQI; When road surface functional performance PQI＜80, road surface breakage is serious, promptly thinks the service life of road surface termination this moment.
On the physics, the definition in " cycle " of " pendulum " is: the time of accomplishing once vibration entirely (3 swings are kept in the center).Imitative this, swing period definition to graticule and be: the number of times of accomplishing and once swing entirely (3 times swing, graticule is kept in the center).
