| Abstract: | On the basis of the principles of fracture mechanics, damage mechanics and pavement distress, the whole process from the create, extension to damage about cement concrete pavement damage is analyzed. Meanwhile the basic reason for pavement crack of concrete pavement during each stage is indicated. It provides a new thought for preventing the slab crack. |
