Table 3.1. Notes on Figures 3.1. to 3.6.
Note 1
Figures 3.1. to 3.6. are not drawn to scale. The minimum sides (both length (L) and
width (W)) of a spall repair shall not be less than 6 in. (150 mm) for Army and Air Force
pavements and 12 in. (300 mm) for Navy pavements, regardless of the spall size. The
locations of the intended sawcuts should be clearly marked.
Note 2
Spalls occur in many sizes and shapes. Repair details shown are intended for removal
and replacement of all deteriorated concrete and to maintain the size of the spall repair
to the minimum practical to ensure a lasting repair while avoiding unecessary removal
of sound concrete.
Note 3
For Navy pavement, joint spalls with actual cavity widths less than 2 in. (50 mm) shall
be repaired by cleaning and filling with joint sealant in lieu of PCC.
Note 4
Where spall repairs are required on each side of a joint or crack, a nonflexible type filler
or insert shall be secured in alignment with the joint or crack after breaking out the
spalled concrete. Under no circumstances should a spall repair bridge a joint or crack.
Note 5
For corner spalls in Army and Air Force pavements, the repair shall be rectangularly
shaped and the sawcut boundaries shall be no less than 6 in. (150 mm) from the joint
corner. For triangular corner spalls in Navy pavements, the repair shall be made
pentagonal to avoid feather-edged corners and to minimize the size of the repair area.
The two sides of the repair area next to the joints should be a minimum of 12 in.
(300 mm) in both length and width. Sawcuts shall be made at least 2 in. (50 mm) from
each side of the spall and extending a minimum of 4 in. (100 mm) perpendicular to the
20
