Cement concrete pavement with novel expansion joints and pre-broken joints
The invention discloses a cement concrete pavement with novel expansion joints and pre-broken joints. The expansion joints and the pre-broken joints adopt upper V-shaped openings, and the upper V-shaped openings can be either independently formed in the transverse or longitudinal expansion joints and the pre-broken joints or simultaneously formed in the transverse and longitudinal expansion joints and the pre-broken joints. According to the pavement disclosed by the invention, the problems that rectangular joints in the conventional cement concrete pavement are unlikely to observe whether water leaks or not, the influence caused by temperature difference change is large, the water sealing effect is poor, post-stage maintenance is difficult, the cost is high, the material selection range is small and the like can be solved.
