Staggered joint longitudinal staggered joint horizontal staggered joint position, horizontal width left picture right picture paving asphalt pavement, layer lap position should be 200mm refers to the left picture right picture paving two layers can be staggered joint; For example, the road width is 30m, the width on the left is 14.9m, and the width on the right is15.1m; The width of the left side of the paving layer is set to 15. 1m, and the width of the right side is set to14.9m. The transverse staggered joints are overlapped by 20cm hot joints. If the residual temperature of continuous paving asphalt does not subside, if the paving asphalt has been rolled and cooled, the joints will be cold. Overlap width: the position with poor meaning of transverse seam is 15. 1m compared with the same period of last year. If the pavement width is 7.4m+7.7m, the pavement width will change, that is, 30cm, that is, the lap width. Longitudinal staggered joints along the road can be laid in layers, that is, the basic horizontal staggered joints should be1m.
