This specification is intended for interlocking concrete pavers used in the construction of paved surfaces and manufactured from cementitious materials, aggregates, chemical admixtures, and other constituents such as integral water repellents. The specification also offers guidelines for physical requirements, sampling and testing, visual inspection, and rejection of specimens.

1.1 This specification covers the requirements for interlocking concrete pavers manufactured for the construction of paved surfaces.

1.2 When particular features are desired, such as weight classification, higher compressive strength, surface textures, finish, color, or other special features, such properties should be specified by the purchaser. Local sellers, however, should be consulted as to availability of units having the desired features.

1.3 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.
