This test method is suitable for both field and laboratory use to determine one or more of the following: 1) The near-surface tensile strength of the substrate as an indicator of the adequacy of surface preparation before application of a repair or overlay material, 2) The bond strength of a repair or an overlay material to the substrate, and 3) The tensile strength of a repair or overlay material, or an adhesive used in repairs, after the material has been applied to a surface. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
