Does the concrete pavement need to be cut in the construction of concrete pavement?
The longitudinal slits in the concrete pavement are designed to divide the joints of the road surface. The function is to cut off the internal stress of the concrete, increase the vertical deformation of the road and prevent the deformation from causing too much damage.
Expansion joints, shrink joints are generally set in the transverse joints, is to prevent the concrete with the temperature changes in the amount of expansion and contraction is large, the concrete longitudinal stress will be crushed or rammed concrete set, the expansion joints width than the general longitudinal
1, when a pavement width is less than the total width of the road and hard shoulder should be set vertical construction joints, due to the vertical adjacent two concrete pouring date is different, the difference between the two concrete strength, in the first construction should
In the longitudinal seam set the rod, the construction of the other should be the first longitudinal re-press the design of the axis of lofting, along the line with a sewing machine to cut off the excess concrete, in the concrete slab
