Concrete Pavement Cracks
What causes a pavement to crack?
This corresponds to field experiences on projects with cement-treated subbases, and asphalt-treated or cement-treated permeable subbases that were known to have bonded to the pavement (9-11). Cracks from bonding to the subbase are likely to initiate from the bottom of the slab and travel toward the slab surface, sometimes reflecting from shrinkage cracks in the stabilized subbase.
