    Significance and Use

    This test method is intended to determine the effects of freezing and thawing on units conforming to the dimensional requirements of Specification C936/C936M while immersed in a test solution. Other types of segmental concrete paving units that do not conform to the dimensional requirements of Specification C936/C936M may be tested using this test method.

    The results from this test method are not intended to provide a quantitative measure of the length of service from concrete paving units conforming to the dimensional requirements of Specification C936/C936M.

    1. Scope

    1.1 This test method evaluates the resistance to freezing and thawing of solid interlocking concrete paving units conforming to the dimensional requirements of Specification C936/C936M. Units are tested in a test solution that is either tap water or 3 % saline solution, depending on the intended use of the units in actual service.

    1.2 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.

    1.3 This standard does not purport to address all of the safety concerns, in any, associated with its use. It is the responsibility of the use of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitation prior to use.
