CHAPTER 13
SPALL REPAIR MATERIALS
13.1. Specifications. The particular repair materials chosen for the repair operation must
conform to the appropriate specifications as discussed below. For Navy pavements, use of
asphalt patching materials for temporary spall repair is allowed. The Army and Air Force do not
allow the use of asphalt patching materials for spall repair. The concrete, curing compound (if
used), sealant (see the section "Crack Sealants"), backer rod (see the section "Backer Materials"),
and joint filler must meet ASTM specifications. For U.S. Army Corps of Engineers construction,
the curing compound must conform to CRD-C300 (Reference 1.3.14.). Joint fillers can be
asphalt- impregnated fiber-board, styrofoam sheeting, sponge rubber, or cork but must conform
to ASTM D 1751 or D 1752. Recommended maximum aggregate size is 3/8 inch (10
millimeters). Type I concrete is the required patching material unless other materials are
approved by the base engineer. Cementitious materials in the PCC shall be portland cement that
conforms to ASTM C 150, Type I, unless other materials are approved by the base engineer.
Type II cements are generally not necessary for repair projects. Type III cements can be
employed when the repaired area must be opened to traffic within 1 to 3 days after placement of
the PCC. The PCC should have a range of 0 to 1/2 inch (0 to 13 millimeters) of slump, and a
throughly tamped in-place specimen must meet a minimum compressive strength of 5,000
pounds per square inch (35 megapascals) at 28 days of age. On U.S. Navy facilities, the
materials chosen must meet all of the specifications outlined in NFGS-02983 (Reference 1.3.10.),
and NFGS-02982 (Reference 1.3.3.). For U.S. Army and Air Force facilities, refer to
CEGS-02980 (Reference 1.3.11.) and CEGS-02760 (Reference 1.3.5.). For U.S. Air Force
pavements repair, see Reference 1.3.6. also. For filling popouts, operators should use a
