Adjustment of the screed: after screed width adjustment, to adjust their camber. Various types of paver arch mechanism is substantially the same tune, can be read directly on the scale after adjusting the camber of the absolute number (mm) cross slope value or percentage, after adjusting the camber to conduct a test shop check, if necessary adjust again

After ironing board width adjustment carried out camber adjustment. Its purpose is to read in the absolute level ruler camber (mm) or percent cross slope and camber adjustment to the design value can be consistent. After adjustment to conduct a test shop check, make adjustments again if necessary. For large paver, arch tone before and after the two institutions, the front arch camber should be adjusted slightly larger than the arch is appropriate. Experience has shown that the former arch is too large, the middle part of the mixture is more, so there is a close and scrapings cents intermediate marks and longitudinal tear stripe; on the contrary, the former arch is too small, even after less than arch, the middle portion of the mixture below normal , so there will be loose in the middle, and is scraped off both sides close bright marks and longitudinal tear streaks phenomenon. Therefore, before and after the arch camber to be adjusted appropriately, generally take a long-width-modulated artificial screed difference before and after the arch of the 3-4mm, width modulated hydraulic telescopic screed 2mm difference is appropriate.

For highway use full-width at half-amplitude time paving the road, when the crown is straight crown, since the road width wide, screed larger self, to the bottom edge of the screed strictly controlled and stalls Shop during regular check. Checking methods can be tracked paver, not rolling in front with measuring rope placed on both sides of the reference line; measured perpendicular to the road center line taut rope, mixed rope Cece amount already paving asphalt top the distance between the faces, each measuring point distance if the same, then the crown is straight and correct; on the contrary, road humps are likely to have erred, it is necessary to adjust.
