1.1 This is a material specification covering hybrid geosynthetic paving mats typically used for, but not limited to, use in joint and localized (spot) pavement repairs; and paving mats intended for curb-to-curb coverage to provide a moisture barrier for the pavement structure and retard reflective cracking in bituminous overlays. They are typically non-woven in construction. This is a material purchasing specification and design review of use is recommended.

1.2 This is not a construction or design specification. This specification is based on hybrid geosynthetic paving mat survivability from installation stresses. The values stated in SI units are to be regarded as the standard.

1.3 For purposes of determining conformance to this specification, values for length or area shall be rounded to the nearest 0.1 m or 0.1 m², respectively. Values for mass shall be rounded to the nearest gram, and for force to the nearest Newton, and volume to the nearest 0.01 L, in accordance with the rounding method in Practice E 29.

1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the standard.

1.5 Specific safety recommendations are presented in Section .

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
