1.1This 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 nonwoven in construction. This is a material purchasing specification, and design review of use is recommended.

1.2This is not a construction or design specification. This specification is based on hybrid geosynthetic paving mat survivability from installation stresses.

1.3For 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 E29.

1.4The 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.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7This 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.
