If proprietary concrete patching materials are to be used in the repair, be sure to follow the
manufacturer's recommendations for bonding agents, mixing, placement, and curing. After the
spall area has been filled, the joint or crack must be sealed.
12.2. Test Area. Before beginning a full-scale patching operation, a test area of spall repair
must be conducted. This ensures familiarity with equipment and materials and any potential
problems with techniques, etc., before beginning the full-scale repair operation. Additional
information on spall repair is available in References 1.3.10. through 1.3.12. All applicable ASTM
test methods are listed in Table 1.1. and information on concretes from the American Concrete
Institute is listed in Table 1.2.
