| Abstract: | Though the trial research on cavity from beneath cement concrete pavement slabs, the distributive regularity of cavity form is obtained in the paper. Accordingly the stress variations of road slabs under different vehicle loads are analyzed and their service life spans are calculated. The result suggests that the cavity beneath cement concrete pavement slabs and the overloading vehicles are the important factors of incipient fractures of cement concrete pavement slabs. |
