defined by one or more high-severity cracks with high FOD potential; or (2) joint is severely
frayed, with high FOD potential (Figures 16.6. and 16.7.). (Note: If less than 2 ft (0.6 m) of the
joint is lightly frayed, the spall should not be counted.)
16.3. How to Count. If the joint spall is located along the edge of one slab, it is counted as one
slab with joint spalling. If spalling is located on more than one edge of the same slab, the edge
