Standard Specification for Utility Segmental Concrete Paving Slabs

ABSTRACT
This specification covers segmental concrete paving slabs manufactured for construction of pedestrian and roof applications for commercial and municipal projects where close dimensional tolerances for thickness, and/or length and width are not required. These slabs can be manufactured with a dry-cast, wet-cast, or hydraulically pressed process. Concrete units covered by this specification shall be made with lightweight or normal weight aggregates or both.
This specification establishes the requirements with respect to materials, physical properties (finished face area, modulus of rupture, resistance to freezing and thawing, dimensional tolerances), visual inspection, sampling and testing, and compliance.
SCOPE
1.1 This specification covers the requirements for segmental concrete paving slabs manufactured for construction of pedestrian and roof applications for commercial and municipal projects where close dimensional tolerances for thickness, and/or length and width are not required. These slabs can be manufactured with a dry-cast, wet-cast, or hydraulically pressed process.  
1.2 Concrete units covered by this specification shall be made with lightweight or normal weight aggregates or both.
Note 1: If particular features are desired, such as weight classification, higher modulus of rupture, 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.
