1.1 This specification covers the requirements for segmental concrete paving slabs used for construction of pedestal-set applications for commercial and municipal projects. These slabs can be manufactured with a dry-cast, wet-cast, or hydraulically pressed process or some combination of these manufacturing processes such as in the hermetically-pressed process.

Note 1: Pedestal-set applications should not be subject to vehicular traffic. If the application will be subjected to vehicular traffic, the pavement system will require alternate materials properties, or structural support, or both.

1.2 Concrete units covered by this specification shall be made with lightweight, or normal weight aggregates, or both.

Note 2: If particular features are desired, such as weight classification, higher concentrated center load capacity, 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 inch-pound units or SI 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.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
