1.1 This specification covers the composition, physical properties, dimensional tolerances, and sampling for tests of inserts placed in portland cement concrete airfield pavement while the concrete is in an unhardened state to form contraction joints. The insert may be partially or totally removed after the concrete has hardened to provide a suitable space for a sealant.

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.
