The disadvantage is that the construction is complicated and there are many horizontal joints. The long-term impact of the wheel on the horizontal joints will easily cause damage to both sides of the joint groove. With the increase of damage, the road surface will be damaged, and it is difficult to repair the damaged road surface. poor performance

Embodiment Construction
[0010] When the concrete pavement construction progresses to the surface layer construction stage, follow the procedures: install formwork, lay sand cushion, set joints, mix materials, pave, vibrate, smooth, maintain, and fill joints. 1. When stretching or shrinking joints, set the stretching or shrinking joints at an angle of 60 degrees or 120 degrees to the longitudinal direction of the road surface, see figure 1 , promptly can realize technical effect of the present invention. Diagonal seam 1 can also be crease seam, see figure 2 .

A construction method for oblique joint seam on concrete pavement is characterized by that the included angle between said joint seam and the longitudinal axis of pavement is 0-180 deg, but not 90 deg. Its advantages are less impact of wheel to joint seam and long service life and high load-bearing power of pavement.
Description
technical field [0001] The invention relates to a construction method for concrete pavement joints. Background technique [0002] Concrete pavement is a pavement built by using cement slurry synthesized by cement and water as binder, crushed stone as aggregate, and sand as filler. After mixing, paving, vibrating and maintaining. Pavement characteristics: strong compression resistance, bending resistance and wear resistance, good water stability and thermal stability, smoothness and roughness suitable for driving safety, strong and durable, low maintenance cost, belonging to high-grade rigid road surface. The disadvantage is that the construction is complicated and there are many horizontal joints. The long-term impact of the wheel on the horizontal joints will easily cause damage to both sides of the joint groove. With the increase of damage, the road surface will be damaged, and it is difficult to repair the damaged road surface. Poor performance. Contents of the inventi...
