ASTM C936-07
(Specification)Standard Specification for Solid Concrete Interlocking Paving Units
Standard Specification for Solid Concrete Interlocking Paving Units
SCOPE
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 SI units are to be regarded as the standard. The values given in parentheses are for information only.
